EP3225 - 25Amp Circuit Breaker

EP3225 - 25 Amp Circuit Breaker

When you're working with an existing electrical system, the last thing you want is guesswork. The EP3225 circuit breaker is built to match the original setup—delivering the exact form, fit, and function needed for compatible ED-A frame panelboards. With a 225-amp rating and a 3-pole configuration, it's designed to handle demanding three-phase applications while maintaining safe, consistent operation. The thermal magnetic trip mechanism reacts to both overloads and short circuits, helping protect your equipment without unnecessary complications. Its plug-on design makes installation straightforward, and the common-trip feature ensures all poles disconnect together when it matters most. If your goal is to keep your system running as intended, this breaker does exactly that—no more, no less.
