More Information

Overview Manuals Contactor Control Protection Logic Service Compatibility Application
  • 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
  • OEM assemblies requiring a loose IntelliVAC contactor-control component
Description
1503VC-BMC4 is an Allen-Bradley IntelliVAC contactor control module supplied as a Series C and D spare for Bulletin 1502 medium-voltage vacuum contactors.

The module accepts AC or DC control power, supervises contactor pickup and holding sequences, provides two status-relay outputs, and includes anti-kiss, anti-pump, delayed-restart and undervoltage protection logic.

Before replacement, confirm the existing contactor series, control-voltage source, interface-connector pinout, DIP-switch settings, external capacitor requirements, enclosure wiring and the current Rockwell spare-part recommendation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which contactors use Allen-Bradley 1503VC-BMC4?
It is a Series C and D IntelliVAC spare associated with Bulletin 1502 medium-voltage vacuum contactors.
What must be matched before replacing Allen-Bradley 1503VC-BMC4?
Match the contactor series, control-power range, connector wiring, DIP-switch settings and external capacitor arrangement.
How should the external capacitor arrangement be handled when replacing Allen-Bradley 1503VC-BMC4?
Match the installed contactor and control-voltage configuration to the Rockwell wiring information; do not transfer or omit external capacitance until its required value and connection are verified.
What protection functions are built into Allen-Bradley 1503VC-BMC4?
It includes anti-kiss, anti-pump, delayed-restart and time-delayed undervoltage functions.
Can Allen-Bradley 1503VC-BMC4 provide status feedback?
Yes. Two normally open status-relay outputs are provided for external indication or control-system input.
What does Rockwell's 1503VC-BMC5 guidance mean for an Allen-Bradley 1503VC-BMC4 replacement project?
The current spare-parts table directs users to order 1503VC-BMC5, but the installed Series C or D contactor, wiring, connectors, switch settings and capacitor arrangement still require an engineering compatibility review.
What commissioning checks are required after installing Allen-Bradley 1503VC-BMC4?
Verify connector seating, control voltage, DIP settings, contactor pickup, holding current, status outputs and undervoltage response under controlled conditions.
