ED43B110L - 110Amp Circuit Breaker

ED43B110L - 110Amp Circuit Breaker

The Siemens ED43B110L is a 110 Amp three-pole molded case circuit breaker designed for use in compatible Siemens SENTRON ED-frame electrical distribution systems. It's most commonly installed as a replacement breaker when an existing ED-frame unit needs to be matched for the same amperage, frame size, and interrupting rating, helping maintain the original panel configuration without modifications.

You'll typically find this breaker protecting 480VAC three-phase distribution circuits in commercial buildings, manufacturing facilities, warehouses, and other industrial environments. Because all three phases disconnect together, it's well suited for feeders, distribution equipment, motor circuits, and other applications where coordinated three-pole protection is required.
