HED43B030 - 30Amp Circuit Breaker

HED43B030 - 30Amp Circuit Breaker

The Siemens HED43B030 is a 30 Amp, 3-pole molded case circuit breaker designed to provide dependable overload and short-circuit protection in 480VAC three-phase electrical distribution systems. As part of the Siemens SENTRON ED frame product family, this breaker features a thermal-magnetic trip unit that responds to prolonged overloads and instantaneous short-circuit conditions to help protect electrical equipment and branch circuits. Before installation, verify that the breaker's frame size, amperage, voltage rating, interrupting capacity, and terminal configuration match your equipment.
