Westinghouse Electric EHD3030L Circuit Breaker

The Westinghouse Electric EHD3030L Circuit Breaker is a three-pole, bolt-on device rated 30 A at 480 VAC, featuring an auxiliary switch and part of the Type EHD family for branch-circuit protection in industrial and commercial distribution systems. It provides a 14 kA interrupt rating and uses a thermal-magnetic trip for 50/60 Hz operation, making it suitable for panelboards, switchgear, motor control centers, HVAC equipment, conveyors, and automation control cabinets that require reliable three-phase overload and short-circuit protection with auxiliary control capability. Mounting is bolt-on with installation suitable for panelboard and switchgear mounts, reflecting its industrial-grade construction. Common replacements include Eaton EHD3030L, Cutler-Hammer EHD3030, and Square D FAL34030.
