EHC3015 - 15Amp Circuit Breaker

EHC3015 - 15 Amp Circuit Breaker

When you’re working on an existing system, the last thing you want is a breaker that doesn’t line up or behave the way the original did. The EHC3015 is built for exactly that situation. It’s a 15 amp, 3 pole thermal-magnetic circuit breaker designed to drop into compatible EHC frame setups without creating new problems. This breaker handles both overloads and short circuits using a thermal-magnetic trip mechanism, which is what most systems in this category were designed around. The trip unit is non-interchangeable, so the protection settings stay fixed—no adjustments, no surprises. It also comes with load terminals already included, which helps speed things up when you’re installing or replacing a unit in the field. With interrupting ratings of 14kA at 480VAC and 18kA at 240VAC, the EHC3015 is suited for typical commercial and industrial applications running three-phase power. It’s rated for use in 40°C environments and built to hold up over time, making it a practical choice when you need something that simply fits and works the way it should.
