Cutler-Hammer EHD2020BU Molded Case Circuit Breaker

Cutler-Hammer EHD2020BU molded case circuit breaker, 2-pole, 20A, 480V, is a compact overcurrent protection device designed for installation in electrical panels and switchgear where 480-volt circuits are used. The model name EHD2020BU identifies this specific unit within the Cutler-Hammer molded case breaker family, and its 20-amp rating provides protection for circuits of that current level, while its 2-pole construction protects two conductors under a single device. With a 480-volt rating, this breaker is suitable for distributing power in systems that operate at or below this voltage, helping to automatically interrupt fault currents to prevent damage to wiring and equipment. The molded case design encloses the switching mechanism and arc-quenching components in a durable, self-contained module, simplifying installation and maintenance within panelboards and switchgear assemblies that require molded case protection.
