HFXD63B175L - 175Amp Circuit Breaker

HFXD63B175L - 175Amp Circuit Breaker

Trying to confirm whether the HFXD63B175L circuit breaker is the right fit for an existing electrical system? Start with the full specification, not just the 175-amp rating. If your system is built around the HFXD6 frame and calls for the same amperage, pole count, trip arrangement, terminal configuration, and interrupting ratings, the HFXD63B175L can provide the intended form, fit, and function for the application. Properly matched, installed, and used within its stated ratings, it is built to last in the job it was designed to do.

Key Features and Benefits

• 175A, 3-Pole Configuration: Designed for compatible electrical systems requiring a 175-amp, three-pole molded case circuit breaker.
• Non-Interchangeable Trip Unit: Uses the specified fixed trip configuration for this model.
• Line and Load-Side Terminals Included: Both terminal sets are included, an important distinction when confirming the exact replacement configuration.
• Suitable for Reverse Feed: Can be used in compatible applications where reverse-fed operation is permitted.
• HACR Rated: Suitable for applications that specifically require an HACR-rated breaker.
• 50/60Hz Operation: Designed for systems operating at either listed frequency.
