The Westinghouse EBH3100 Shunt Trip Circuit Breaker is a 100 A, 480 VAC, 3‑pole device engineered for remote emergency shutdown and overload protection in industrial and commercial power distributions. It combines thermal‑magnetic circuit protection with an integrated shunt‑trip function, allowing remote trip and disconnect in motor control centers, automation panels, conveyors, HVAC systems, and other safety‑critical equipment. Designed for three‑phase services, it provides dependable protection against overloads and short circuits while enabling remote disconnect operation in industrial machinery and facility power distribution infrastructure, and it supports manual reset and switching. Common replacements include Eaton HFD3100 Shunt Trip, Siemens HED43B100ST, and Square D EDB340100SA.
