Express Delivery Eaton / Cutler-Hammer EC3090 – 90A 3 Pole Molded Case Circuit Breaker

Part of the legacy Westinghouse E-Frame family, this 90A Eaton Cutler-Hammer MCCB provides reliable power distribution for commercial and industrial facilities. It is specifically designed to mount into older CS5, MP40, MP100, MP200 panelboards, and EE switchboards. As an obsolete EC series unit, it can be substituted with the modern EHD3090. Rated for 10 kAIC at 240VAC, the breaker features fixed thermal-magnetic trip units and includes load-side lugs for immediate wire termination.
