JA3175W - 175Amp Circuit Breaker

JA3175W - 175Amp Circuit Breaker

If you're tracking down a JA3175W for existing equipment, there are several details you'll want to match—not just the 175-amp rating. This 3-pole Type JA circuit breaker uses a thermal-magnetic, non-interchangeable trip unit and carries a 40°C rating. For compatible legacy equipment that calls for this combination of amperage, poles, Type JA configuration, trip arrangement, and interrupting ratings, the JA3175W provides the specifications needed for a straightforward form, fit, and functional replacement evaluation. These products are built to last, while correct application still depends on matching the breaker to the equipment requirements.

Key Features and Benefits

• 175A current rating: Gives you a clear starting point when matching the breaker to existing equipment specifications.
• Three-pole configuration: Designed for equipment requiring a 3-pole breaker arrangement.
• Type JA: An essential identifier when checking compatibility with an existing breaker or equipment documentation.
• Thermal-magnetic operation: Uses the specified thermal-magnetic circuit breaker design.
• Non-interchangeable trip unit: The trip configuration is fixed as a non-interchangeable design, an important detail for replacement matching.
• No terminals included: Helps distinguish the JA3175W configuration when the existing installation requires a breaker supplied without terminals.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification information was provided in the available specifications for the JA3175W. These certifications should not be inferred from the Type JA designation, electrical ratings, or other supplied specifications.

Where It Works Best

The JA3175W 175A 3-pole circuit breaker makes sense as a replacement for compatible existing and legacy equipment that specifically calls for a Type JA breaker with a 175A rating, thermal-magnetic operation, a non-interchangeable trip unit, and the stated voltage-dependent AIC ratings.
