- Controls pickup and hold sequencing for Bulletin 1502 vacuum contactors
- Accepts the documented AC or DC control-power ranges
- Provides anti-kiss, anti-pump, delayed-restart and undervoltage logic
1503VC-BMC4 is an Allen-Bradley IntelliVAC contactor control module designed for compatible Bulletin 1502 medium-voltage vacuum contactors.
It supervises the contactor command and coil sequence, supports electrically held and mechanical-latch arrangements, and supplies two normally open status-relay outputs.
Before installation, verify the contactor Series, control voltage, connector wiring, switch settings, external capacitor arrangement and the applicable Rockwell replacement guidance.
Availability, condition, price, and shipping time for 1503VC-BMC4 are confirmed during quotation.

- Coordinates pickup and hold current for Bulletin 1502 vacuum contactors
- Supports electrically held and mechanical-latch contactor arrangements
- Uses programmable control behavior selected through onboard switches
- Anti-kiss logic prevents incomplete contactor closure
- Anti-pump logic prevents repeated pickup from a maintained command
- Undervoltage timing supports coordinated dropout and restart behavior
- Series C and D installations require the corresponding wiring information
- Connector and capacitor arrangements must match the installed contactor
- Current Rockwell spare guidance identifies 1503VC-BMC5 as the order replacement
- Medium-voltage motor starters using Bulletin 1502 vacuum contactors
- Medium-voltage feeder control using Bulletin 1502 vacuum contactors
