EP3175 - 175Amp Circuit Breaker

EP3175 - 175 Amp Circuit Breaker

When you're maintaining or restoring an existing electrical distribution system, the EP3175 circuit breaker provides a dependable, form-fit-function replacement that matches original specifications. Built with a 3-pole configuration and rated at 175 amps, this thermal magnetic-trip breaker is engineered to deliver consistent protection against overloads and short circuits in commercial and industrial panelboards. Its plug-on design allows for straightforward installation in compatible systems. At the same time, the common-trip mechanism ensures all poles disconnect simultaneously—an essential feature for maintaining safety and code compliance in multi-phase applications. Designed to fit six 1-inch panel spaces, the EP3175 securely fits within ED-A frame setups and is built to last in demanding environments where reliability matters.
