Eaton CHH3150H2X - 150 A, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Eaton CHH3150H2X, a robust 150 A, 3-pole bolt-on molded case circuit breaker engineered for dependable branch circuit protection in panelboards and load centers. Designed to withstand the realities of daily electrical distribution, this unit delivers a secure, vibration-resistant bus connection thanks to its bolt-on mounting, keeping critical connections tight even in compact or high-traffic panels.

The heart of its protection is a thermal-magnetic trip unit, delivering stable, repeatable performance. It responds precisely to overloads and short circuits, reducing nuisance trips during normal inrush while still safeguarding circuits against damaging faults. With a 3-pole configuration, it is well-suited for 3-phase systems that power commercial equipment, light industrial machinery, and multi-wire residential installations that require balanced phase protection.
