Westinghouse HMCP003A0D Circuit Breaker, 3A, 3-Pole

The Westinghouse HMCP003A0D Circuit Breaker is a compact, three-pole protection solution tailored for demanding industrial electrical service, maintenance, and replacement projects. Rooted in the trusted Case-series lineage, this unit is designed to safeguard three-phase circuits with a precise 3 A rating, helping you isolate and protect equipment quickly and reliably.

• Three-pole protection for 3-phase systems ensures simultaneous disconnection of all conductors, delivering safer shutdowns for motors, conveyors, and other multi‑phase loads.
• 3 A amperage provides targeted protection for small or sensitive control circuits without triggering nuisance trips.
• Case-series compatibility aligns with Westinghouse Case-series panels and components, simplifying replacements and ensuring cohesive electrical installations.
• Part-number-driven fit Use HMCP003A0D to confirm compatibility with your specific application; verify fit based on your panel, environment, and electrical requirements.
• Ideal for replacements and maintenance a reliable choice for upgrading aging breakers or stocking on-hand for planned service work in industrial settings.
• Support when you need it unsure about fit? Send a message, and we’ll help verify compatibility with your equipment and project needs.

Practical use scenarios

• Replacing worn or obsolete breakers in factory control panels, MCCs, and distribution boards that service 3‑phase equipment.
• Implementing a consistent protection strategy across new installations that mirror the Case-series configuration.
• Performing scheduled maintenance where safe power isolation of three-phase circuits is essential.
