Eaton KD3150 - 150 A, 600 V, 3-Pole Circuit Breaker | AmpState

The Eaton KD3150 is a robust 3-pole molded case circuit breaker engineered for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a 150 A rating and a 600 V capacity, this unit is built to handle the demanding needs of modern electrical systems while keeping panel space efficient.

• Compact molded case design maximizes available space in panels, helping you fit essential protection without compromising layout.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance by combining overload sensing with instantaneous short-circuit response, even as ambient conditions change.
• 3-pole configuration ideal for balanced protection in 3-phase systems, ensuring reliable operation across all phases.
• OEM panel compatibility designed to work with matching Eaton and OEM loadcenters and panelboards for straightforward, plug-and-play replacement in existing installations.
• Versatile application suitable for residential, commercial, and light industrial environments, providing flexible protection for feeders and branch circuits.

What makes this KD3150 stand out?

Rather than a one-size-fits-all breaker, the KD3150 is purpose-built to deliver precise protection where you need it most. The molded case design reduces panel crowding, while the thermal-magnetic trip unit ensures that protection scales with load and temperature, preventing nuisance trips and ensuring fast response when a fault occurs. At 150 A and 600 V, it’s positioned to safeguard sizeable branch circuits and feeders without oversizing your protection strategy.

Ideal use cases

• Main or feeder protection in commercial and light industrial panelboards.
• Replacement in OEM or compatible loadcenters where a reliable 3-pole, 150 A breaker is required.
• Protection for 3-phase equipment and circuits in span constructions, HVAC distribution, and large lighting systems.
