NJL631175 - 175Amp Circuit Breaker

NJL631175 - 175 Amp Circuit Breaker

The NJL631175 is a 175-amp, 3-pole thermal-magnetic molded-case circuit breaker with a bolt-on design. It’s a straightforward choice when you need to replace an NJL breaker and match the equipment's specifications.

This breaker is rated 22k AIC at 600VAC, 30k AIC at 480VAC, and 42k AIC at 240VAC. It has a 40°C rating and comes with load-side lug terminals. The breaker measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep, which are important measurements to check when matching an existing installation.

You may also see this breaker referenced as NJL632175. If that number appears on an existing breaker, equipment documentation, or maintenance records, it can help when cross-referencing the correct part.

Built to last, the NJL631175 is well suited for maintaining older electrical equipment where matching the original breaker’s amperage, pole configuration, mounting style, dimensions, and interrupting ratings matters.

Where It Works Best

• The NJL631175 circuit breaker is intended for equipment that calls for an NJL-type 175A, 3-pole, bolt-on molded case breaker with matching electrical ratings and dimensions. It can be especially useful when maintaining legacy equipment and replacing the existing breaker without changing the required form, fit, or function.
• Before installation, compare the breaker with the existing unit and equipment requirements. Check the part number, amperage, number of poles, voltage, AIC ratings, mounting style, dimensions, and terminal configuration to ensure everything matches.
