PowerPact B Control Auxiliaries
PowerPact B-Frame Remote Electrical Trip
The following voltage release auxiliaries are operated remotely by an electrical trip command:
MX shunt trip
MN undervoltage release
MN undervoltage release with time-delay unit. The time-delay unit helps to overcome nuisance tripping due to transient voltage dips. The time delay is adjustable up to three seconds.
Voltage release auxiliaries are installed in the case under the front face of the circuit breaker. The presence and characteristics of a voltage release auxiliary are displayed through a window on the front face.
The characteristics of voltage release auxiliaries comply with UL 489, CSA 22.2 No 5, and IEC/EN60947- 2 recommendations.
