MBK100A - 100 Amp Circuit Breaker Description
MBK100A - 100 Amp Circuit Breaker
If you need a replacement 100 Amp main circuit breaker, the MBK100A is built for applications that call for a 2-pole breaker with a 22kA interrupting rating at 240VAC. It uses a thermal-magnetic trip design that helps protect electrical systems from overloads and short-circuit conditions. That combination makes it a common choice for service equipment and distribution panels where reliable circuit protection is required. The breaker is rated for operation at 40°C and 50/60Hz. It accepts either copper or aluminum conductors from #1 AWG through 300 kcmil and is intended for use with 75°C wire. An HACR Type rating also makes it suitable for qualifying heating, air conditioning, and refrigeration equipment. Before installation, always verify compatibility with your panel and follow all applicable electrical codes.
