EHC3050 - 50Amp Circuit Breaker

EHC3050 - 50 Amp Circuit Breaker

If you’re working with an existing EHC setup, the EHC3050 is designed to drop in without complications. It’s a 3-pole, 50-amp thermal-magnetic circuit breaker designed for standard commercial and industrial systems that require consistent, known protection characteristics. This breaker handles both overloads and short circuits using a thermal-magnetic trip mechanism, which is what most systems of this type were originally designed around. The trip unit is fixed (non-interchangeable), so once it’s installed, it operates exactly as expected—no field adjustments needed. It’s rated for use in 40°C environments and comes with load terminals, making installation straightforward. With interrupting ratings of 14kA at 480VAC and 18kA at 240VAC, the EHC3050 fits applications where those fault levels are already part of the system design. It’s built to last and intended for maintaining equipment that’s already in place—not changing how it operates, just keeping it protected.
