Product description
Shipping
The Eaton HMCP100R3CB3 100A 3-Pole Circuit Breaker is a rugged, reliable solution for protecting three-phase electrical systems. With a 100 amp rating across three poles, this device locks in stable overcurrent protection for motors, transformers, and distribution panels, helping prevent damage from overloads and short circuits. Built by Eaton, it’s designed to integrate seamlessly with compatible panelboards and electrical installations.
Key specifications
- Part Number: HMCP100R3CB3
- Current rating: 100 A
- Poles: 3
- Brand: Eaton
Why a 3-pole design matters
Three-pole protection ensures simultaneous disconnection of all live conductors in a 3-phase circuit. This coordinated shutdown reduces arc energy and provides consistent fault clearance across every phase, which is crucial for safeguarding balanced three-phase loads such as motors and HVAC equipment.
Ideal applications
- Commercial and light industrial panelboards requiring dependable three-phase protection
- Three-phase motors, pumps, and conveyors in manufacturing or processing facilities
- HVAC equipment, transformers, and distribution circuits that demand robust overcurrent protection
Installation and compatibility
Designed for use within compatible Eaton panelboards and distribution panels, the HMCP100R3CB3 offers straightforward integration for established electrical systems. When replacing or upgrading, verify that your panel accepts HMCP-series breakers and that the trip characteristics align with your system requirements. For optimal safety and compliance, follow local electrical codes and consult a licensed electrician during installation.
Practical guidance and tips
- Match the 100 A rating to the feeder or branch circuit it protects to ensure proper overload protection without nuisance trips.
- Inspect connections for tightness during installation to maintain reliable operation and minimize contact resistance.
- Schedule periodic reviews of protective devices in your electrical system to address aging components and maintain system reliability.
