Eaton QCR1050 - 50 A, 120 V, 1-Pole Circuit Breaker | AmpState

Meet the Eaton QCR1050 — a 50 A, 120 V, 1-pole molded-case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Its compact, space-savvy design pairs with a precise thermal-magnetic trip unit to provide stable, repeatable protection where every ampere counts.

• Space-efficient molded-case design: Maximizes panel capacity without compromising protection, letting you power more circuits in the same footprint.
• Thermal-magnetic trip unit: Provides reliable performance across temperature variations and fault currents, reducing nuisance trips while ensuring fast response to short circuits.
• 50 A, 120 V, 1-pole: Ideal for common residential branch circuits and selected commercial or light industrial loads that require dependable protection.
• OEM-compatible: Engineered to fit and function with matching Eaton OEM load centers and panelboards, helping maintain proper mounting, signaling, and code conformity.
• Versatile application: Suitable for a range of environments—from home electrical panels to light commercial installations—where robust, predictable protection is essential.

Why this matters in real-world use: A single-pole, 50 A breaker protects wiring, outlets, lighting runs, and small-appliance circuits from overloads and fault conditions. The thermal-magnetic design ensures consistent trip behavior across seasonal and load variations, so you get reliable protection when you need it most. By sticking to the QCR1050 within Eaton’s QCR lineup, you preserve compatibility, trip curves, and installation familiarity across your panel system.
