Accessories

Auxiliary contacts allow remote indication of the circuit breaker contact states. They can be used for signalling, electrical locking, and relaying. They are available in two versions: standard and low level. They include a terminal block. The auxiliary circuits leave the circuit breaker through a hole provided for this purpose. They perform the functions described in the following table, depending on where they are located in the circuit breaker.

Auxiliary contact slots

GV5PB	GV6PB

GV5PB/ GV6PB motor protection circuit breakers can be equipped with a thermal fault module. This module has:

• A contact to indicate an overload fault in the circuit breaker

• A contact to open the contactor. In the event of overload or phase unbalance, this output is activated 400 ms before circuit breaker tripping to open the contactor and avoid circuit breaker tripping.

Electric trips allow the circuit breaker to be tripped via an electrical control signal.
Undervoltage release (UVR)—GV7AU:

• 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.

• 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.

Shunt trip (SHT)—GV7AS:

• Trips the circuit breaker when the control voltage rises above 0.7 times the rated voltage.

• Impulse type 20 ms or maintained control signals

Operation—GV7AU or GV7AS:

• When the circuit breaker has been tripped by a GV7AU undervoltage release or a GV7AS shunt trip, it must be reset locally.

• Tripping has priority over manual closing. If a tripping command is present, manual action does not result in closing, even temporarily, of the contacts.

• Durability: 50% of the mechanical durability of the circuit breaker.

AL150HD Lug Kit

S37447 Terminal Shield

Lug Kits

The connectors for GV5PB snap directly onto the device terminals. GV5PB also has an insert kit which is used for bus bar connection. GV6PB connectors are screwed directly to the device terminals.

Terminal Shields

Terminal shields are used for front connection with cables or insulated bars. They comprise two parts assembled with captive screws, forming an IP40 cover. The top part is equipped with sliding grids for precise adaptation to cables or insulated bars. The rear part completely blocks off the connection zone. Terminal shields may be mounted upstream and downstream of the circuit breaker.

GV6A30P Direct Rotary Handle

The circuit breaker can be operated with an optional direct mount rotary handle. The rotary handles comes in two colors, Gray/Black and Yellow/Red, and includes a device for locking the circuit breaker in the O (Off) position by means of up to three padlocks with a shackle diameter of 5–8 mm (padlocks not included). An MCC conversion accessory allows the direct rotary handle to be mounted on the enclosure door. In this case, the door cannot be opened if the circuit breaker is in the “ON” position. Circuit breaker closing is inhibited if the enclosure door is open and prevents the device from being closed if the door is open.

S32599 Extended Rotary Handle

GV7AP02 Extended Rotary Handle

Extended rotary handles allow you to operate from the front of the switch board a circuit breaker that is installed in the back of an enclosure. Provides IP55 protection. The extended rotary handle comprises:

• A unit which is screwed onto the front accessory cover of the circuit breaker

• A handle mechanism and front plate assembly to be fitted on the enclosure door

• An extension shaft which must be adjusted

Minimum and maximum distances between the mounting surface and the door:

• 7.28–23.62 in. (185–600 mm) for GV5PB

• 8.23–23.62 in. (209–600 mm) for GV6PB

The extended rotary handle includes a device for locking the circuit breaker in the O (Off) position by means of up to three padlocks with a shackle diameter of 5–8 mm (padlocks not included) and disables opening the enclosure door.
