Eaton HMCPE003A0X - 3 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton HMCPE003A0X is a 3-amp, 480-volt, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters.

Key to its reliability is a secure bolt-on mounting that delivers a rigid, vibration-resistant bus connection—crucial in commercial and light industrial environments where equipment and panels experience movement or vibration.

• Thermal-magnetic trip unit: delivers accurate, repeatable protection across temperature changes, helping to coordinate with other protection devices and minimize nuisance trips.
• 3-pole design for three-phase distribution, with a 480V rating to handle higher voltage circuits in demanding settings.
• OEM-compatible—designed to drop into matching Eaton OEM loadcenters and panelboards for fast, reliable replacement or upgrade.
• Versatile applications: ideal for residential, commercial, and light industrial installations requiring robust branch-circuit protection without sacrificing space or ease of installation.

The Eaton HMCPE003A0X (Part Number HMCPE003A0X) is a thermal-magnetic molded case circuit breaker built to protect small-diameter or low-load circuits from overcurrent while guarding against short circuits that could affect an entire panel. With its 3A rating and 480V capability, it serves as a reliable safeguard for critical distribution in panelboards and load centers.

Practical use cases include protecting lighting runs, control circuits, or small equipment feeders in panelboards and load centers where a robust 3-pole, 480V breaker is required. In environments with vibration—such as mechanical rooms, manufacturing floors, or spaces with heavy equipment—the bolt-on configuration helps maintain a solid, low-resistance connection over time.

Compared to other branch-circuit breakers, this model emphasizes long-term stability and straightforward service. The bolt-on mounting simplifies field replacement and reduces the risk of loose connections, translating to fewer unexpected trips and more uptime for essential systems.

Installation tips: pair this breaker with the correct OEM panelboard or loadcenter and follow the prescribed torque for bolt-on mounting to maintain the integrity of the bus connection and the thermal-magnetic trip performance.
