Description
A drop-in replacement for older systems, the Eaton EC2030 is a 2-pole, 30-amp molded case circuit breaker. It utilizes thermal-magnetic technology for reliable protection. This bolt-on unit mounts into Cutler-Hammer Type EC panelboards. For modern upgrades, the EHD2030 is the designated substitute for this legacy Westinghouse E-Frame profile. With a 10 kAIC rating at 240VAC, it handles standard commercial loads. The breaker features load side lugs for 14-1/0 AWG conductors.Specifications
