Description

The Allen-Bradley 1503VC-BMC4 is an IntelliVAC contactor control module engineered for medium-voltage vacuum contactor applications. As a core component of the Bulletin 1503VC IntelliVAC family, this module provides a scalable, reliable solution for managing Bulletin 1502 vacuum contactors rated at 400 A and 800 A, supporting systems up to 7,200 volts. It features universal input voltage compatibility, allowing for deployment across diverse global power infrastructures without the need for voltage-specific hardware variants.

Features

  • Universal supply voltage: 110–240V AC (50/60 Hz) or 110–250V DC.
  • Consistent pick-up time performance across the entire rated voltage range.
  • Selectable drop-out times (50–240 ms) for precise coordination with upstream power fuses.
  • Integrated anti-kiss and anti-pumping protection to prevent rapid reclosure and contact bounce.
  • DIP switch configurable control parameters for field adjustments without specialized software.
  • Status indication via onboard LEDs and relay outputs for integration into higher-level control systems.
  • Power loss ride-through (TDUV) capability.

Applications

  • Mining and Minerals: Reliable control for crushers, conveyors, and ventilation fans in harsh, high-dust environments.
  • Oil and Gas: Management of high-capacity pumps and compressors in extraction and refining operations.
  • Water/Wastewater: Precise control for large-scale pumping stations requiring high uptime.
  • HVAC and Infrastructure: Control for chillers and large air handlers in data centers and commercial facilities.
  • Renewable Energy: Power conditioning and distribution for grid-scale energy projects.
