MX36800 - 800 Amp Circuit Breaker

MX36800 - 800 Amp Circuit Breaker

When replacing a circuit breaker in an existing electrical system, getting the right fit matters. The MX36800 is an 800-amp800-amp, 3-pole molded-case circuit breaker designed for compatible commercial and industrial electrical equipment. It features a plug-in connection, Micrologic® trip technology, and thermal-magnetic protection to help manage overloads and short circuits. Its current-limiting design also helps reduce fault current under applicable conditions.

One useful feature of the MX36800 is its adjustable trip settings. You can adjust the long-time ampere rating and delay to match the system's protection requirements. At the same time, the adjustable instantaneous pickup lets you set the response threshold for short-circuit conditions. The breaker has an interrupting rating of 25 kA at 600 VAC, 65 kA at 480 VAC, and 65 kA at 240 VAC. These ratings matter when matching a replacement breaker to the existing electrical equipment.

The MX36800 measures 14.75 inches high, 8.96 inches wide, and 5.74 inches deep. Its plug-in configuration is designed for electrical assemblies that accept this breaker type. Built to last, the MX36800 is a practical choice for maintaining existing power distribution equipment without changing the original system design. Just be sure to check the mounting arrangement, electrical ratings, and trip characteristics before using it as a replacement.
