NM632600 - 600Amp Circuit Breaker

NM632600 - 600Amp Circuit Breaker

When you're replacing a circuit breaker in existing equipment, getting the details right matters. The NM632600 is a 600-amp, 3-pole molded-case circuit breaker with a bolt-on mounting configuration and thermal-magnetic protection. It's intended for compatible electrical systems that call for this specific NM-type breaker setup.

The NM632600 carries interrupting ratings of 22k A.I.C. at 600VAC, 30k A.I.C. at 480VAC, and 42k A.I.C. at 240VAC. It measures 15.5 inches high, 8.19 inches wide, and 4.13 inches deep, and includes load-side lug terminals. Those details are worth checking closely when matching a breaker to existing equipment. The part number matters, of course, but dimensions, mounting style, amperage, poles, voltage, interrupting rating, and terminal configuration all matter in finding the right fit. With its molded-case construction and straightforward thermal-magnetic design, the NM632600 is built to last when properly installed and used within its specified ratings.

Key Features and Benefits

• 600A rating for equipment designed to use a 600 amp circuit breaker.
• Three-pole configuration for compatible three-phase applications.
• Thermal-magnetic protection provides overcurrent protection appropriate to the breaker's intended application.
• Bolt-on mounting matches equipment designed around this installation style.
• Interrupting ratings of 22k at 600VAC, 30k at 480VAC, and 42k at 240VAC.
• Load-side lug terminals are included, an important detail when checking an existing breaker configuration.
• 40°C rating.
• The molded case construction is built to last in the proper application.
• Well suited to form, fit, and functional replacement situations where the existing equipment requires the NM632600 configuration.

Material Compliance and Certifications

• Specific certification listings and material-compliance information were not provided with the available specifications for the NM632600 circuit breaker. For that reason, we are not making any certification or compliance claims here.
• If a particular listing, certification, or material requirement is necessary for the installation, check the markings on the breaker and the applicable technical documentation before putting it into service.

Where It Works Best

• The NM632600 makes the most sense in compatible legacy electrical equipment that already calls for this type of breaker. It may be used in industrial electrical systems, distribution equipment, switchgear, and similar installations that require a 600 amp, 3-pole, bolt-on thermal-magnetic molded-case circuit breaker with these ratings.
• For replacement work, don't rely on appearance alone. Two breakers can look similar while having different electrical or mounting characteristics. Check the existing equipment requirements against the part number, 600A rating, three-pole configuration, voltage, A.I.C. rating, dimensions, bolt-on mounting, and load-side lug arrangement. When those details line up, you have a much clearer picture of whether the NM632600 is the right form, fit, and functional replacement for the application.
