Description
Designed for heavy-duty power distribution, the Siemens CM3B500 is a 500A, 3-pole current-limiting circuit breaker. It provides reliable thermal-magnetic trip functions for industrial facilities. This bolt-on MCCB installs into Siemens switchboards, power panelboards, and motor control centers. As a legacy component, it offers a precise fit for older systems and is officially replaced by the CMD63B500. Amp-trap limiters restrict fault currents, achieving a 100kAIC rating at 480VAC.
