E3015 - 15A Circuit Breaker

E3015 - 15A Circuit Breaker

When you're dealing with a three-phase electrical system, the replacement breaker has to match the original setup closely—otherwise the panel just won’t behave the way it should. The E3015 15 Amp 3-Pole Circuit Breaker is built for exactly that kind of situation. It’s a Type E thermal-magnetic breaker designed for systems that require a 15 Amp rating, 3-pole configuration, and 240VAC service, commonly found in legacy industrial and commercial electrical distribution equipment.

The E3015 is rated for a 10kA interrupting capacity at 240VAC, making it suitable for a range of general-purpose applications within its listed electrical limits. It also includes a non-interchangeable trip unit, which helps maintain the original factory configuration of the equipment it is installed in. With a 40°C temperature rating and included load terminals, it fits cleanly into compatible panels without requiring modifications to the existing layout.

In real-world use, this breaker is typically selected during maintenance or replacement work where the goal is simple—keep the system running as it was originally designed. Matching the correct amperage, pole count, and voltage rating helps avoid unnecessary changes to the panel and keeps downtime to a minimum.
