EP3175 - 175Amp Circuit Breaker

EP3175 - 175Amp Circuit Breaker

The Siemens EP3175 is a 175 Amp, 3-pole ED-A plug-on circuit breaker designed for use in compatible Siemens electrical distribution equipment. It combines a thermal magnetic trip unit with a common-trip design, so all three poles open together if an overload or short circuit occurs. When you're replacing an existing breaker, matching the correct type, amperage, and mounting configuration matters. The EP3175 is manufactured to provide the proper form, fit, and function for those applications and, like many Siemens breakers, is built to last when installed and maintained correctly.

Where It Works Best

The Siemens EP3175 is used in compatible Siemens panelboards and load centers that require a 175 Amp, 3-pole ED-A plug-on circuit breaker. It's a good fit for maintenance projects, equipment repairs, or replacing a breaker with the same electrical ratings and mounting style.
