J3175 - 175Amp Circuit Breaker

J3175 - 175Amp Circuit Breaker

When you're replacing a breaker in existing equipment, "close enough" isn't much help. The J3175 offers a specific set of ratings to match: 175 amps, three-pole, J-frame construction, and 14k AIC at 480VAC. It uses a thermal-magnetic, non-interchangeable trip unit and comes with load-side terminals. The breaker is also rated at 40°C. If those characteristics line up with the breaker and equipment specifications you're working from, the J3175 provides the form, fit, and function needed for a proper replacement.

Key Features and Benefits

• 175A, 3-pole configuration gives you two of the most important specifications for quickly checking a potential replacement.
• J-frame design helps narrow the match when replacing a breaker in compatible existing or legacy equipment.
• Uses a thermal-magnetic trip mechanism, rather than leaving the trip technology open to interpretation.
• The trip unit is non-interchangeable, an important detail when confirming the exact breaker configuration.
• Load-side terminals are included with the breaker.
• Carries a 40°C rating; check against the installation requirements.

Material Compliance and Certifications

No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification information was included in the supplied specifications for the J3175. Those certifications should not be assumed based on the breaker type or frame designation.

Where It Works Best

The J3175 is a practical fit for compatible existing and legacy electrical equipment that specifically calls for a 175A, 3-pole Type J/J-frame breaker with a thermal-magnetic, non-interchangeable trip unit. It is especially important to check the frame and physical dimensions when replacing an older breaker; matching the amperage alone doesn't establish compatibility.
