HED43B030L - 30Amp Circuit Breaker

HED43B030L - 30Amp Circuit Breaker

The Siemens HED43B030L is a 30 Amp, 3-pole molded case circuit breaker engineered to provide dependable overload and short-circuit protection in 480VAC three-phase electrical distribution systems. Part of the trusted Siemens SENTRON ED frame family, this breaker features a thermal-magnetic trip unit that helps protect electrical circuits by responding to both sustained overload conditions and instantaneous short circuits. Before installation, always verify that the breaker's frame size, amperage, voltage rating, interrupting capacity, and terminal configuration match your equipment.
