EB3015 - 15Amp Circuit Breaker

EB3015 - 15 Amp Circuit Breaker

The EB3015 circuit breaker is a 3-pole, 15-amp thermal-magnetic breaker designed for use in compatible EB frame panelboards commonly installed in electrical systems manufactured before 1989. It provides dependable protection against overloads and short circuits in three-phase circuits operating up to 240VAC, with an interrupting capacity of 10kA.

Because many facilities still rely on legacy distribution equipment, finding the correct replacement breaker is important for maintaining the original design of the panel. The EB3015 is built with a non-interchangeable thermal-magnetic trip unit, delivering consistent protection characteristics for circuits that require a 15-amp rating. Its 40°C operating rating supports use in typical electrical room conditions, and the included load terminals help simplify installation for qualified electricians working on maintenance or repair projects.

This breaker follows the original EB frame form and dimensions, allowing it to fit properly into compatible panels without altering the existing setup. For facilities maintaining older infrastructure, the EB3015 helps keep systems operating as intended while preserving panel compatibility. Like many molded case breakers built for industrial electrical equipment, these units were designed for long service life when installed and maintained properly.
