Eaton CHH2150H4X - 150 A, 240 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CHH2150H4X sets a new standard for dependable branch circuit protection in residential, commercial, and light-industrial panel environments. With a robust 150A rating and 240V operation, this 2-pole bolt-on molded-case circuit breaker is built to endure demanding service conditions while keeping wiring secure and organized.

• Bolt-on mounting: provides a rigid, vibration-resistant bus connection that stays locked in even in busy electrical spaces.
• Thermal-magnetic trip: delivers stable, repeatable protection by responding to both overloads and short circuits with precision.
• 2-pole design: simultaneously interrupts both hot conductors for safer fault isolation and improved system safety.
• OEM compatibility: engineered to work with matching Eaton loadcenters and panelboards, ensuring a precise fit and reliable performance.
• Versatile application: ideal for residential service panels, commercial distribution panels, and light-industrial installations requiring dependable protection.
