Eaton KD3100W - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered by Eaton, the KD3100W is a 3-pole, bolt-on molded case circuit breaker rated at 100A and 600V. It delivers dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters, supported by a thermal-magnetic trip unit that provides stable, repeatable protection across diverse electrical loads. Built for rugged, vibration-prone environments, its secure bolt-on mounting ensures a rigid bus connection, reducing movement and arc-prone faults in demanding installations.

Key advantages that matter in real-world panels

• Secure bolt-on mounting – a rigid connection to the bus bar minimizes vibration-related wear and maintains consistent electrical contact over time.
• Thermal-magnetic trip unit – combines thermal and magnetic protection for precise fault detection, delivering fast, predictable responses to overloads and short circuits.
• OEM compatibility – designed to pair with matching Eaton OEM load centers and panelboards for straightforward retrofits and replacements without compatibility guesswork.
• Three-pole, 100A, 600V design – ideal for three-phase systems common in commercial and light industrial settings, while still suitable for residential panel configurations requiring robust three-phase protection.
• Versatile applications – suitable for residential, commercial, and light industrial protection needs where reliable, long-term performance matters.

Who benefits from the KD3100W

• Electrical contractors upgrading or replacing breakers in panelboards and loadcenters that require a 3-pole, 100A, 600V bolt-on solution.
• Builders and facility managers seeking a dependable, long-lasting protection device for new installations or retrofits in three-phase electrical systems.
• Homeowners or facility operators performing service upgrades who need a compatible, OEM-grade breaker that aligns with existing Eaton panel infrastructure.
