HP3B100 - 1000Amp Circuit Breaker

HP3B100 - 1000Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, the details matter. The HP3B100 is an HP3 molded-case circuit breaker with a 1000-amp rating and a 3-pole configuration, intended for applications where its electrical ratings and physical dimensions match the existing system. It's a straightforward choice for compatible legacy electrical equipment that calls for these specifications. Built to last and designed for its intended application, the HP3B100 gives maintenance professionals a clearly defined set of ratings to match against the breaker being replaced.

Key Features and Benefits

Material Compliance and Certifications

Specific material-compliance information and certification listings were not included in the available product specifications. For that reason, no UL, CSA, RoHS, or other certification is claimed here.

If a particular listing or material-compliance requirement applies to your installation, verify it using the breaker nameplate, applicable documentation, and the requirements of the equipment where the breaker will be installed.

Where It Works Best

The HP3B100 is best suited for existing electrical distribution equipment that requires an HP3 1000A 3-pole molded-case circuit breaker with matching physical and electrical characteristics. This makes it particularly relevant for maintenance and replacement work involving compatible legacy systems.

For an accurate replacement, don't rely on amperage alone. Check the existing breaker's part number, breaker type, number of poles, system voltage, AIC requirement, dimensions, and temperature rating. Those details help determine whether the HP3B100 provides the correct form, fit, and function for the application.
