NX361200G - 1200 Amp Circuit Breaker

NX361200G - 1200 Amp Circuit Breaker

The NX361200G is a Type NX molded-case circuit breaker made for your compatible electrical equipment using the NX plug-in design. For anyone maintaining an older electrical system, matching the breaker to the existing equipment is important. Size, connection, voltage, and interrupting rating all matter. The NX361200G measures 12.12 inches high, 14.62 inches wide, and 6.43 inches deep, with interrupting ratings of 65k AIC at 600VAC, 100k AIC at 480VAC, and 125k AIC at 240VAC. It is a current-limiting, thermal-magnetic breaker with Micrologic functionality. There’s a good amount of adjustment built into its protection functions, too. The long-time ampere rating and delay are adjustable, as are the short-time ampere rating and delay. It also includes adjustable instantaneous pickup and ground-fault pickup and delay. For a legacy installation that calls for an NX361200G, this breaker provides the original plug-in connection style along with the specified protection functions and electrical ratings. It’s a practical choice when the job is to maintain the existing system rather than change its configuration. These breakers were built to last and remain useful for keeping compatible electrical equipment in service.

Material Compliance and Certifications

• The available specifications for the NX361200 G did not include specific certification and material-compliance information, so we are not claiming additional approvals or certifications here. Check the breaker markings and the documentation for the equipment it will be installed in to verify any required listings, approvals, or compliance information.

Where It Works Best

• The NX361200G Type NX circuit breaker is intended for compatible legacy electrical equipment that uses this plug-in breaker configuration. Think replacement and maintenance applications where keeping the existing setup intact is important.
• The part number is a good starting point, but it shouldn’t be the only check. Before installation, compare the breaker’s dimensions, Type NX configuration, plug-in connection, voltage, AIC rating, and protection requirements with the existing equipment. When those details match the application, the NX361200G provides the form, fit, and functions needed to maintain the system in its intended configuration.
