Description

Designed specifically for legacy installations, the Eaton EH1030 functions as a 30-amp, single-pole molded case circuit breaker. It offers reliable LI (long-time and instantaneous) protection with a 14kAIC rating at 277VAC. This bolt-on unit is engineered to fit perfectly into discontinued Westinghouse and Eaton NEHB panelboards. By serving as an exact substitute for EHB1030 and EHD1030 breakers, it allows facility managers to maintain existing infrastructure without costly panel upgrades.
