VCP-T Digitrip 1150V

The VCP_T Digitrip line of trip units consists of the model 1150V that conforms to UL standards, and model 1150Vi that conforms to IEC standards. Appendix B in the 1150V trip unit instructional leaflet includes a troubleshooting guide.

Protection settings options:

  • LSIG - Long delay, Short Delay, Instantaneous, Ground Fault Trip
  • Instantaneous trip can be disabled

External control power is not required to operate the basic overcurrent protection functions; the trip unit operates through current sensors mounted in the breaker. When the breaker trips, an LED on the trip unit will indicate the cause of trip.


  • Arc Flash Reduction Maintenance Mode (ARMS) - can reduce arc flash incident energy that is generated on a fault condition
  • INCOM communications
  • PT module for voltage and power metering
    • Located on the top terminals by default
    • Option to mount on the bottom terminals

The power module (DPS):

  • Three voltage ratings: 120 Vac, 230 Vac, and 24–48 Vdc
  • 10 VA
  • Display will be functional even when the breaker has no load
  • Without auxiliary power, no communications or voltage data

The current metering tolerance is 1% of the rating plug value for phase and neutral, and 2% of the rating plug value for ground, applicable for 5-100% of the rating plug value.

The voltage metering tolerance is 3%.

The green status LED at the bottom right of the trip unit blinks approximately once per second to indicate normal operations. 

Time/current curves are available here.
