Westinghouse ED2100 Bolt-On Circuit Breaker

The Westinghouse ED2100 Bolt-On Circuit Breaker is a 2-pole, 100 Amp, 240V AC Type ED circuit breaker designed for bolt-on mounting in industrial electrical distribution and high-capacity branch protection systems. It delivers reliable overload and short-circuit protection for equipment and circuits in motor control panels, commercial power distribution gear, industrial machinery, and HVAC installations where high interrupt capacity matters. This 1-phase device features a 65kA interrupt rating, manual reset and switching capability, and heavy-duty construction for industrial environments. Commonly used for branch circuit and equipment protection, it is compatible with distribution panels and control equipment and is suited for both new installations and retrofits in manufacturing facilities. Common replacements include Eaton ED2100, Siemens HED42B100, and Square D EDB24100, reflecting its role in standard high-amperage bolt-on breaker schemes.
