Overview
The Westinghouse HMCP050K2C is a Series C motor circuit protector (MCP) engineered for reliable protection in three-phase industrial motor applications. This 50-amp, 3-pole breaker combines instantaneous-only magnetic protection with a compact molded-case design. Rated for 600VAC and 250VDC operation, the HMCP050K2C delivers a 65 kA interrupt rating at 480V, making it suitable for motor starter combinations in demanding industrial environments.
Key Features
- Instantaneous magnetic trip function — I-type protection without thermal delay for motor short-circuit detection
- Adjustable trip settings — Magnetic instantaneous range of 150–500 amps for application flexibility
- Dual-voltage rated — 600VAC / 250VDC operation for AC and DC industrial circuits
- Feed-thru connection — Allows pass-through wiring for integrated panel designs
- Compact molded-case — Designed for panel or DIN rail mounting in tight spaces
- Bottom and top lugs included — Simplifies installation in motor control centers
Technical Specifications
The HMCP050K2C meets UL 489 and CSA C22.2 standards, ensuring compliance with North American industrial safety requirements. Its instantaneous-only protection design eliminates thermal-magnetic complexity, reducing nuisance trips and improving response time in motor overload scenarios.
