HED43B080 - 80Amp Circuit Breaker

HED43B080 - 80Amp Circuit Breaker

When dependable circuit protection is required in a three-phase electrical system, the Siemens HED43B080 is built for the job. This 80 Amp molded case circuit breaker features an ED frame, a thermal-magnetic trip unit, and a 42kA interrupting rating at 480 VAC, making it a practical choice for many commercial and industrial power distribution applications. The thermal element responds to sustained overloads, while the magnetic trip reacts quickly during short-circuit events to help protect your connected equipment.
