JA3175 - 175Amp Circuit Breaker

JA3175 - 175Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details matter. JA3175 is a 175-amp, 3-pole Type JA circuit breaker with a thermal-magnetic, non-interchangeable trip unit and a 40°C rating. For legacy or existing equipment that calls for this particular Type JA configuration, the JA3175 is a practical form, fit, and functional replacement to consider. These products are built to last, but the right match still comes down to confirming the electrical ratings, trip configuration, terminals, and physical dimensions required by the equipment.

Key Features and Benefits

• 175-amp rating for equipment requiring this specific current rating.
• 3-pole configuration makes pole-count verification straightforward when matching an existing breaker.
• Type JA design provides an important identifier for replacement and compatibility checks.
• Thermal-magnetic operation with a non-interchangeable trip unit.
• Load-side terminals are included, so there is no guesswork about the supplied terminal configuration.
• 40°C rated, providing another specification to check against the existing breaker.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was included in the supplied specifications for the JA3175. Those certifications should not be assumed based on the breaker type or electrical ratings alone.

Where It Works Best

The JA3175 is appropriate for compatible existing and legacy equipment calling for a 175A, 3-pole Type JA breaker with thermal-magnetic operation and a non-interchangeable trip unit. It is especially important to note that this version includes load-side terminals when comparing it with the breaker currently in service.
