Westinghouse Cutler-Hammer EHD3070 Circuit Breaker

The WESTINGHOUSE Cutler-Hammer EHD3070 is a 70 A, three‑pole circuit breaker designed for 480 VAC three‑phase distribution in industrial and commercial electrical systems, providing branch circuit protection and power control in motor control centers, switchboards, and industrial panelboards. Manufactured as part of the Type EHD series, it features bolt‑on mounting, a thermal‑magnetic trip, and a 14 kA interrupt rating, with UL listing and operation at 50/60 Hz to deliver reliable overload and short‑circuit protection in heavy‑duty equipment. This unit’s installation type is panelboard and switchboard mount, and it is built with industrial grade construction to withstand demanding environments, making it suitable for industrial machinery, HVAC systems, conveyors, and motor control assemblies that require robust three‑phase protection. Common replacements and cross‑reference options include Eaton EHD3070, Cutler-Hammer EHD3070, and Square D FAL34070, reflecting its compatibility with both legacy and modern electrical distributions.
