Installation and Connection
-
The auxiliary switch (OF) and alarm switch (SD) indication contacts snap into cavities behind the front accessory cover of the circuit breaker and their presence is visible through the semi-transparent cover.*
-
One switch model serves for all indication functions depending on where it is installed in the circuit breaker.
-
Each NO and NC spring terminal may be connected by one 0.5–1.5 mm² (20–16 AWG) stranded copper wire and by two wires for the common point. See Indication Contacts for indication contacts wiring diagrams.
PowerPacT B Accessories Video –
Auxiliary Contacts Catalog Numbers
Standards
-
Indication contacts comply with UL 489, CSA C22.2 No. 5 and IEC 60947-5-1 Standards.
-
Indication contacts have also been tested according IEC 60 947-5-4 standard.
-
Indication contacts are Listed for field installation per UL file E103955 and Certified under CSA file 177007.
Shunt Trip (MX) and Undervoltage Release (MN)
A voltage release can be used to trip the circuit breaker using a control signal.
Shunt trips serve primarily for remote, emergency-off commands. Undervoltage releases disconnect under low-voltage conditions.
Installation and Connection
-
Voltage releases snap into a cavity under the front accessory cover of the circuit breaker.
The presence and characteristics of the voltage release is visible from the front face through a window. -
Each spring terminal may be connected by one 0.5–1.5 mm² (20–16 AWG) stranded copper wire.
For information on electrical characteristics and wiring recommendations of MN/MX, see Shunt Trip (MX) and Undervoltage Release (MN) Wiring Rules
Operation
-
The circuit breaker must be reset locally after being tripped by shunt trip (MX) or undervoltage release (MN).
-
Tripping by the shunt trip or undervoltage release has priority over manual closing; in the presence of a standing trip order such an action does not result in any closing, even temporarily, of the main contacts.
-
Endurance: 50% of the rated mechanical endurance of the circuit breaker.
Standards
-
MN/MX voltage releases comply with with UL 489, CSA C22.2 No. 5 and IEC 60947-2 Standards.
-
MN/MX voltage releases are Listed for field installation per UL file E103955 and Certified under CSA file 177007.
Shunt Trip (MX)
Shunt Trip (MX)
-
Trips the circuit breaker when the control voltage rises above 70% of its rated voltage (Un).
-
Control signals can be impulse type of ≥ 20 ms or maintained control signals.
-
A 110-130 Vac shunt trip is suitable for ground-fault protection when combined with a Class I ground-fault sensing element.
-
Continuous duty rated coil *.
Shunt Trip (MX)
Undervoltage Release (MN)
-
Trips the circuit breaker when the control voltage drops below 35% of its rated voltage.
-
Between 35% and 70% of the rated voltage, opening is possible but not guaranteed.
-
Above 70% of the rated voltage, opening does not take place.
-
Continuous duty rated coil.
-
Circuit breaker closing is possible only if the voltage exceeds 85% of the rated voltage. If an undervoltage condition exists, operation of the closing mechanism of the circuit breaker will not permit the main contacts to touch, even momentarily. This is commonly called “Kiss Free”.
Undervoltage Release (MN)
Time Delay Unit for Undervoltage Release
-
A time delay unit for the MN eliminates the risk of nuisance tripping due to a transient voltage dip lasting less than 200 ms for fixed delay units and up to 3 seconds for adjustable units. For shorter micro-outages, a system of capacitors provides temporary supply to the MN at V > 0.7 Vn to ensure not tripping.
-
The correspondence between MN and time-delay units is shown below.

Device Padlocking
The circuit breaker may be locked in the OFF position by using one to three padlocks (not supplied) or in the ON position after customer modification of the rotary handle before installation, padlock shackle 3/16–5/16 in. (Ø4–8 mm). Locking in the ON position does not prevent the circuit breaker from tripping if an overload or short circuit condition occurs. In this case, the handle remains in the ON position after the circuit breaker trips. Unlocking is required for the handle to go to the tripped position then the OFF position to reset the circuit breaker.
Variations: Door Locking
Door locking built-in functionality can be activated by the customer to prevent opening the door when the circuit breaker is ON or in trip position. For exceptional situations, door locking can be temporarily bypassed with a tool by qualified personel to open the door when the circuit breaker is closed.

The door-mounted extended rotary handle kit is made up of:
-
a rotary mechanism that is mounted to the front accessory cover of the circuit breaker.
-
a handle assembly (handle mechanism and nut) that is mounted on the door. The handle mechanism is always secured in the same position, whether the circuit breaker is installed vertically or horizontally.
-
a cut-to-length extension shaft.
The handle assembly is fixed with a nut (Ø 22 mm) to make assembly easier. The Laser Tool (GVAPL01) can be used to accurately align the hole to be cut in the door with the circuit breaker.
Operation With Door Closed
The door mounted handle makes it possible to operate a circuit breaker installed in an enclosure from the front with the door closed. The door mounted operating handle maintains:
-
suitability for isolation
-
indication of the three positions OFF (O), ON (I) and tripped (Trip)
-
visibility of the trip unit when the door is open
-
degree of protection of the handle on the door: IP54 or IP65 as per IEC 529.
Mechanical Door Locking
A standard feature of the extended rotary handle is a locking function, built into the shaft, that prohibits door opening when the circuit breaker is in the ON or tripped positions.
Door locking can
be temporarily bypassed with a tool by qualified personnel to open
the door without opening the circuit breaker. This operation is not
possible if the handle is locked by a padlock.
Device and Door Padlocking
Padlocking locks the circuit breaker handle and disables door opening:
-
The handle may be locked in the OFF position using 1 to 3 padlocks diameter 3/16–5/16 in. (Ø 4–8 mm). Padlocks are not supplied.
-
A voluntary customer modification of the black handle allows locking in the ON and OFF positions. Locking in the ON position does not prevent the circuit breaker from tripping if an overload or short circuit condition occurs. In this case, the handle remains in the ON position after the circuit breaker trips. Unlocking is required for the handle to go to the tripped position then the OFF position to reset the circuit breaker.
Operation With Door Opened
The indication of the three positions OFF (O), ON (I) and tripped (Trip) is visible on the extended rotary handle mechanism. The circuit breaker itself may be locked in the OFF position when the door is opened by one padlock / lockout hasp, diameter 3/16–5/16 in. (Ø 4–8 mm). An optional open door shaft operator can be used to operate the circuit breaker when the door is opened. This UL508A accessory complies with NFPA79.
Shaft Length
The shaft length is calculated using the distance between the back of the circuit breaker and the door:
-
minimum shaft length is 7.87 in. (200 mm)
-
maximum shaft length is 23.62 in. (600 mm)
-
shaft length must be adjusted to the particular installation.
Models
-
Standard with black handle (IP54).
-

Standards
The door-mounted rotary operating handle is UL Listed under file E103955 and CSA Certified under file 177007.
Side Rotary Handles
Installation
The side-mounted rotary handle is compatible with 3- and 4-pole unit-mount circuit breakers.
The side-mounted rotary handle kit is made up of:
-
a rotary mechanism that has to be mounted to the front accessory cover of the circuit breaker using three screws.
-
an assembly (handle and nut) that mounts on the side (left or right) of the enclosure.
-
a cut-to-length extension shaft.
The handle assembly is fixed with a nut (Ø 22 mm) to make assembly easier.
Operation
The side-mounted rotary handle makes it possible to operate a circuit breaker installed in an enclosure from the side. The side mounted rotary handle maintains:
-
suitability for isolation.
-
indication of the three positions OFF (O), ON (I) and tripped (Trip) is visible on the handle (outside the panel) and on the rotary mechanism (inside the panel).
-
visibility of and access to the trip unit when the door is open.
-
degree of protection of the handle on the side: IP54 or IP65 as per IEC 529.
Device Padlocking
The handle may be locked in the OFF position using 1 to 3 padlocks diameter 3/16–5/16 in. (Ø 4–8 mm). Padlocks are not supplied.
The black handle can be modified during installation to allow locking in the ON and OFF positions. Locking in the ON position does not prevent the circuit breaker from tripping if an overload or short circuit condition occurs. In this case, the handle remains in the ON position after the circuit breaker trips. Unlocking is required for the handle to go to the tripped position then the OFF position to reset the circuit breaker.
Shaft Length
The shaft length is calculated using the distance between the nearest side of the circuit breaker and the side of the enclosure:
-
Minimum shaft length is 1.77 in. (45 mm).
-
Maximum shaft length is 18.90 in. (480 mm).
-
Shaft length must be adjusted to the particular installation.
Models
-
Standard with black handle (IP54).
-
VDE type with red handle and yellow bezel for machine tool control (IP54).
-
Standard with an IP65 universal handle (red handle and yellow bezel).
IP54 models are suitable for mounting on the flat surface of enclosures rated Type 12. IP65 models are suitable for use in Type 12, 3R and/or 4X enclosure applications.
Standards
The side-mounted rotary operating handle is UL Listed under file E103955 and CSA Certified under file 177007.
Locks and Sealing Accessories
Locks
Padlocking systems can accept up to three padlocks with diameters of 3/16–5/16 in. (5–8 mm); padlocks not supplied. Locking in the OFF position provides isolation as per IEC 60947-2. Rotary handle has integral padlocking capability. |
Interlocking of Circuit Breakers with Toggle Control
Interlocking involves padlocking the toggle handles on two devices which may be either circuit breakers or automatic switches.
Authorized positions:
-
one device closed (ON), the other open (OFF)
-
both devices open (OFF).
The system is locked using up to three padlocks (shackle diameter 3/16–5/16 in. [5 to 8 mm]).
The devices must be unit mount construction, circuit breakers can be mounted via backpan mount or DIN rail. Interlocking is not available for I-Line constructions.
Manual Mechanical Interlocking System
Some installations use two power supply sources to counter any temporary loss in the main supply. A mechanical interlocking system is required to safely switch between the two sources. The replacement source can be a generator set or another network.
The mechanical interlocking system is made up of:
-
two B-frame devices
-
mechanical interlock, which prevents handle movement of one device from the OFF position while the other device is in the ON position.
Available as field-installable kit LV426909.
