NJJ232225 - 225Amp Circuit Breaker

NJJ232225 - 225Amp Circuit Breaker

If you're replacing a breaker in existing equipment, getting the details right matters. The NJJ232225 is a 225-amp, 2-pole molded-case circuit breaker with a thermal-magnetic trip and bolt-on mounting. It has a 22 kA AIC rating at 240VAC and a 40 °C rating. Load-side lug terminals are included. This breaker measures 10.13 inches high, 8.25 inches wide, and 3.88 inches deep, so you can compare these specifications with the breaker already in your equipment. The NJJ232225 is especially useful for maintaining compatible legacy electrical systems where the original mounting style, electrical ratings, dimensions, and terminal setup must match. Don't make the selection more complicated than it needs to be: compare the NJJ232225 specifications with your existing breaker and equipment requirements. When those details line up, you have a breaker designed to provide the required form, fit, and function. It's built to last when properly installed and used within its specified ratings.

Material Compliance and Certifications

• The available specifications for the NJJ232225 do not include specific material compliance information or certification details. Check the markings on the individual breaker and applicable product documentation when a particular certification or compliance standard is required.
• Local codes and equipment requirements can vary, so confirm suitability for a specific installation before installing the breaker.

Where It Works Best

• The NJJ232225 makes the most sense for compatible legacy electrical equipment that calls for an NJJ-type, 225A, 2-pole, bolt-on molded-case circuit breaker with a 22k AIC rating at 240VAC. You can use it for replacement and maintenance applications when its physical and electrical specifications match the existing system.
• And that match is important. Two breakers can have the same amperage and still not be interchangeable. Before installation, compare the part number, breaker type, amperage, poles, voltage, AIC rating, bolt-on mounting, terminal configuration, and physical dimensions with the existing breaker and equipment requirements.
• For the right application, the NJJ232225 is a straightforward way to keep compatible older electrical equipment in service while maintaining the required breaker configuration. A qualified electrical professional should verify final compatibility and installation.
