137 products
Siemens molded case circuit breakers are used with Sentron panelboards and SB switchboards. Their current-carrying parts, mechanisms, and trip devices are contained in a molded case. In the event of a fault, they interrupt the current to prevent electrical damage in high-power applications, like industrial control panels, commercial OEM, and electrical distribution equipment.
ED-Frame Siemens Molded Case Circuit Breakers
ED-frame Siemens molded case circuit breakers are rated up to 125A and 480VAC and interrupt excessive current flows to protect devices from electrical damage. They're used in enclosures, switchboards, panelboards, and load centers. Their current-carrying parts, mechanisms, and trip devices are contained in a molded case.
