HED43B100L - 100Amp Circuit Breaker

HED43B100L - 100Amp Circuit Breaker

When your electrical system calls for a 100 Amp, 3-pole ED-frame circuit breaker, the Siemens HED43B100L is built to match those requirements. This molded case circuit breaker uses a thermal-magnetic trip unit that reacts to both long-term overloads and sudden short circuits, helping protect your downstream equipment and electrical distribution systems. Rated for 480 VAC with a 42kAIC interrupting capacity, it is commonly used in commercial and industrial power distribution where the original equipment specifies this breaker.
