NM632150 - 150Amp Circuit Breaker

NM632150 - 150Amp Circuit Breaker

The NM632150 is a 150-amp, 3-pole molded case circuit breaker for use in compatible electrical equipment. It has a bolt-on mounting design, thermal-magnetic trip, and a 40°C rating. Load-side lug terminals are included. This breaker has interrupting ratings of 22 kAIC at 600VAC, 30 kAIC at 480VAC, and 42 kAIC at 240VAC. It measures 15.5 inches high, 8.19 inches wide, and 4.13 inches deep. If you're maintaining older electrical equipment, the details matter. A breaker can have the correct amperage and still not be right for the application because of differences in mounting, dimensions, poles, voltage, or interrupting rating. The NM632150 is intended for applications where this particular NM configuration matches the existing equipment. It's built to last and offers a straightforward replacement option when the electrical and physical specifications match.

Material Compliance and Certifications

• Material compliance and certification details were not provided with the available specifications for the NM632150. If a particular listing, certification, or material requirement applies to your installation, confirm it from the breaker label or supporting product documentation. This includes requirements such as UL or RoHS where applicable.

Where It Works Best

• The NM632150 circuit breaker is best suited for replacement and maintenance work on compatible existing electrical equipment. It's a good fit when the system calls for a 150A, 3-pole, bolt-on NM molded case circuit breaker with the ratings and dimensions shown above.
• When matching a breaker to older equipment, don't rely on amperage alone. Check the number of poles, mounting arrangement, voltage, AIC rating, dimensions, terminal setup, and other equipment requirements. If those specifications match the existing application, the NM632150 can provide the form, fit, and function needed to keep the equipment in service.
