Eaton Quicklag QC Single-Pole Thermal-Magnetic Circuit Breaker, 120/240V

Eaton Quicklag QC Single-Pole Thermal-Magnetic Circuit Breaker, 120/240V

The Eaton Quicklag QC Single-Pole Thermal-Magnetic Circuit Breaker delivers dependable overcurrent protection for industrial electrical systems and panelboards. Rated 120/240V with a 10 kAIC interrupt rating, this Type QC industrial circuit breaker uses a thermal-magnetic trip mechanism to protect single-pole circuits from sustained overloads and high fault currents. Its non-interchangeable design and cable-in/cable-out connection make it a practical choice for facilities and contractors that need code-compliant, reliable circuit protection on industrial-grade panelboards. Eaton engineers the Quicklag QC series for consistent trip performance across the demanding conditions common to industrial and commercial electrical distribution equipment.
