JL3B175 - 175Amp Circuit Breaker

JL3B175 - 175Amp Circuit Breaker

With the JL3B175, there are several details worth putting side by side with the breaker you're replacing. It carries a 175A rating, has three poles, and uses a JL3 frame. The JL3B175 is built to last, with the straightforward ratings and measurements needed to evaluate form, fit, and function in compatible existing or legacy electrical equipment.

Key Features and Benefits

• 175A, three-pole configuration gives you two immediate identifiers to check against the existing breaker.
• JL3 frame provides another important reference when confirming compatibility.
• Supplied identification includes Type ET, 400 Ampere "JL" Frame.
• 40°C, rated per the available product specifications.
• Molded case circuit breaker construction for applications calling for this particular JL3 configuration.

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 JL3B175. These approvals should not be assumed. Where a particular certification or standard is required, check the breaker labeling and applicable product documentation before installation.

Where It Works Best

The JL3B175 is a practical choice for compatible existing and legacy electrical equipment that specifically calls for a 175A, three-pole molded case circuit breaker with a JL3 frame and matching electrical characteristics. Its published dimensions also give you concrete numbers to work with when checking the available mounting space.

For replacement work, check the whole specification rather than stopping at the 175A rating. The frame type, pole count, physical dimensions, system voltage, and required AIC rating should all align with the requirements of the equipment at the breaker's installation site.
