Brand New Siemens HED43B110 – 110A 3 Pole Molded Case Circuit Breaker

Built for heavy-duty commercial environments, this 110A bolt-on breaker provides essential thermal-magnetic protection. It is engineered for integration within Siemens Sentron panelboards and SB switchboards. The device secures firmly to the busbar and includes load-side lugs. When transitioning to newer infrastructure, this model is superseded by the 3VA5111-6EC31-0AA0. Delivering a 42kA interrupting rating at 480VAC, the HACR-rated unit handles significant fault currents safely.
