Circuit Breakers
Dual-Break Rotating Contacts
All PowerPacT H-, J-, and L-frame circuit breakers are equipped with dual-break rotating contacts that reduce the amount of peak current during a short-circuit fault. This reduces the let-through currents and enhances equipment protection. |
|
Reduced Let-Through Currents |
|
The moving contact has the shape of an elongated “S” and rotates around a floating axis. The shape of the fixed and moving contacts are such that the repelling forces appear as soon as the circuit reaches approximately 15 times In. Due to the rotating movement, repulsion is rapid and the device greatly limits short-circuit currents, whatever the interrupting level of the unit (D, G, J or L). The fault current is extinguished before it can fully develop. Lower let-through currents provide less peak energy, reducing the required busbar bracing, lowering enclosure pressure, and delivering improved series or combination ratings. See Current-Limiting. |
High Ampere Interrupting Ratings (AIR)
Circuit breakers are available with interrupting ratings up to:
-
200 kA at 240 Vac delta
-
200 kA at 480 Vac delta
-
100 kA at 600 Vac delta.
See Interrupting Rating for additional performance levels.
Internal Operating Mechanism
PowerPacT H-, J-, and L-frame circuit breakers have an over-center toggle mechanism providing quick-make, quick-break operation. The operating mechanism is also trip-free, which allows tripping even when the circuit breaker handle is held in the “ON” position. Internal cross-bars provide common opening and closing of all poles with a single operating handle.
All PowerPacT circuit breakers have an integral push-to-trip button in the cover to manually trip the circuit breaker. This should be used as part of a regular preventive maintenance program.
Handle Position Indication
The circuit breaker handle can assume any of three positions, ON, tripped or OFF as shown. The center tripped position provides positive visual indication that the circuit breaker has tripped.
The circuit breaker can be reset by first pushing the handle to the extreme “OFF” position. Power can then be restored to the load by pushing the handle to the “ON” position.
Visi-Trip Breaker Locator
Provides a visual light alert when a breaker may require attention.
The Visi-Trip LED handle aids in quickly locating a circuit breaker that requires attention. Inspect the handle position for circuit breaker trip indication. The VisiTrip handle will flash an LED light as described in the table below.
Wait five seconds between handle operation and push-to-trip button operation to ensure that the Visi-Trip handle is in standby. Tripping the circuit breaker too soon after toggling may result in the Visi-Trip handle not operating as intended. If a nuisance LED flashing occurs, it can be reset by toggling the circuit breaker. If toggling the circuit breaker is not desired, LED flashing will reset after six hours. When performing annual maintenance in accordance with MCCB Field Testing and Maintenance Guide (0600IB1201), operate the push to trip button (if equipped) to verify the Visi-Trip functionality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take note of the battery health.

Circuit Breaker Ratings
The interrupting rating is the highest current at rated voltage the circuit breaker is designed to safely interrupt under standard test conditions. Circuit breakers must be selected with interrupting ratings equal to or greater than the available short-circuit current at the point where the circuit breaker is applied to the system (unless it is a branch device in a series rated combination). Interrupting ratings are shown on Interrupting Rating and on the faceplate label on the front of the circuit breaker.
Reverse Feeding of Circuit Breakers
The standard unit-mount H-, J-, and L-frame circuit breakers have sealed trip units and may be reverse fed. For catalog numbers, refer to the following tables:
Circuit breakers with field-interchangeable trip units (designated by the suffix T or R and labeled “LINE” and “LOAD”) cannot be reverse fed. Neither can circuit breaker frames without terminations or trip units.
Current-Limiting
The current-limiting attributes of PowerPacT H-, J-, and L-frame circuit breakers provide greater protection for downstream devices by limiting the let-through current in the event of a fault. The current-limiting capabilities of HJ/HL/HR, JJ/JL/JR, and LJ/LL/LR frame circuit breakers are documented with Underwriters Laboratories and Canadian Standards Association. These current-limiting circuit breakers ship with a label that identifies them as UL/CSA Current-Limiting Circuit Breakers. (The HD/HG, JD/JG, and LD/LG circuit breakers do not carry the UL Current-Limiting label).
The trip curves with let-through data are available in the trip curve section in this catalog, see Trip Curves.
Please note that as let-through curves for UL Listed / CSA Certified Current-Limiting Circuit Breakers, these curves are maximum let-through values.
100% Rated
Some models of the H-, J-, and L-frame circuit breakers are UL Listed / CSA Certified to be applied at up to 100% of their current rating. Because of the additional heat generated, the use of specially-designed enclosures on H- and J-frame circuit breakers and 194°F (90°C) rated wire is required when applying circuit breakers at 100% of continuous current rating. (H-, J-, and L-frame circuit breakers can use aluminum or copper lugs.) Markings on the circuit breaker indicate the minimum enclosure size and ventilation required. The 194°F (90°C) wire must be sized according to the ampacities of the 167°F (75°C) wire column in the NEC. Circuit breakers with 100% rating can also be used in applications requiring only standard (80%) continuous loading.
100% ratings are valid for:
-
Three-pole H/J-frame unit mount and busbar connection
-
Three- pole/four-pole L-frame 250 A and 400 A unit mount
-
Three-pole L-frame 250 A and 400 A I-Line
-
Rear connection and switches
Corner-Grounded Delta Ratings (1Ø-3Ø)
Circuit breakers suitable for corner-grounded circuits are marked 1Ø-3Ø. For additional information, refer to data bulletin 2700DB0202, Corner-Grounded Delta (Grounded B Phase) Systems.
Special Applications
Protection of Industrial Control Panels
PowerPacT H-, J-, and L-frame circuit breakers are also used in industrial control panels. They serve as incoming devices or can be combined with contactors to protect motor feeders:
-
compliance with worldwide standards including IEC 60947-2 and UL 508 / CSA C22.2 N°14
-
overload and short-circuit protection
-
installation in universal and functional type
PowerPacT H-, J-, and L-frame circuit breakers equipped for motor protection functions as described in the following pages can be used in industrial control panels. The accessories for the PowerPacT H-, J-, and L-frame circuit breakers are suitable for the special needs of these applications
400 Hz Applications
Impact on Protective Devices
The current in 400 Hz systems has higher losses caused by eddy currents and an increase in the skin effect (reduction in the useful cross-sectional area of conductors). The higher losses cause additional temperature rise in circuit breakers subjected to the higher frequency current. To remain within the rated temperature-rise limits of devices, current derating is required. For circuit breakers equipped with MicroLogic electronic trip units, only the current rating (Ir) must be derated. See “Current Derating Maximum Ir Setting” below. On circuit breakers equipped with thermal-magnetic trip units, the current rating (In) must be derated and the magnetic trip setting Im must be increased. See “Current Rating (In) and Magnetic Trip Setting (Im) Rerating” below.
Breaking Capacity in 400 Hz, 480 V Systems
The power levels of 400 Hz applications rarely exceed a few hundred kW with relatively low short-circuit currents, generally not exceeding four times the rated current

MicroLogic Electronic Trip Units
MicroLogic 3.2/3, 5.2/3 A or E and 6.2/3 with A or E measurement functions are suitable for 400 Hz. The use of electronics offers the advantage of greater operating stability when the frequency varies. However the units are still subject to temperature rise caused by the frequency.
The practical consequences are:
-
limit settings: see the Ir derating table below
-
the long-time, short-time and instantaneous pick-ups are not modified (see MicroLogic 3 Trip Units or MicroLogic 5/6 A or E Trip Units)
-
the accuracy of the displayed measurements is 2% (Class II)

Shunt Trip (MX) or Undervoltage Trip (MN) Voltage Release
at 400 Hz and 440 V
For circuit breakers on 400 Hz systems, only 125 Vdc undervoltage trip (MN) or shunt trip (MX) releases may be used. The release must be supplied by the 400 Hz system through a rectifier bridge (to be selected from the table below) and an additional resistor with characteristics depending on the system voltage.
