CA3175 - 175Amp Circuit Breaker Description

CA3175 - 175 Amp Circuit Breaker

The CA3175 circuit breaker is a 3-pole, 175-amp molded case circuit breaker designed for dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on a CA frame and calibrated for operation at 40°C, this breaker provides thermal-magnetic protection for branch circuits and feeder applications operating up to 240VAC. With a 10kA A.I.C. rating, it is suited for installations where available fault current does not exceed this interrupting capacity. The unit features a non-interchangeable trip unit and includes both line-side and load-side lugs, making it a direct, form-fit-function replacement for compatible legacy systems. Designed to meet the practical demands of facility maintenance and electrical service professionals, the CA3175 is built to last and maintain safe, consistent circuit protection where it is installed.

Key Features and Benefits

  • 175 Amp Continuous Rating: Supports medium-duty commercial and industrial loads.
  • 3-Pole Configuration: Provides protection across three-phase electrical systems.
  • 10kA Interrupting Capacity at 240VAC: Rated to safely interrupt fault currents up to 10,000 amps.
  • CA Frame Type: Ensures proper compatibility with panels and equipment designed for CA-frame breakers.
  • Non-Interchangeable Trip Unit: Factory-calibrated trip mechanism for consistent performance.
  • Includes Line and Load-Side Lugs: Simplifies installation without requiring separate lug kits.
  • 40°C Rated: Designed for standard ambient operating conditions common in electrical rooms and industrial facilities.
  • Form, Fit, and Function Replacement: Suitable for maintaining and servicing compatible existing electrical systems.
