ED63B125L - 125Amp Circuit Breaker

ED63B125L - 125 Amp Circuit Breaker

The ED63B125L is a 125-amp, 3-pole circuit breaker built for use in systems that take an ED6 frame. It’s typically used as a direct replacement in existing panels where the original specs need to be matched—both in size and electrical rating. With interrupting capacities of 18kA at 600VAC, 25kA at 480VAC, and 65kA at 240VAC, it fits a range of standard commercial and industrial applications. This breaker is HACR rated, so it’s commonly used with HVAC equipment, and it can be installed in reverse feed setups if the system calls for it. It comes with both line and load terminals already in place, which helps keep installation simple. Like others in this category, it’s designed for consistent use over time when installed and maintained properly.
