Westinghouse QHCW2020 - 20A, 2-Pole, Circuit Breaker

Meet the Westinghouse QHCW2020 — a 20A, 2-Pole Circuit Breaker engineered for dependable overcurrent protection in demanding electrical environments. The 2-Pole design provides robust protection across both conductors, helping keep your distribution panels and motor control centers running safely and reliably.

Designed for flexible installation in panelboards, switchboards, and control panels, this breaker interrupts both lines when an overcurrent event occurs. That means downstream wiring and connected equipment stay safeguarded, reducing the risk of heat buildup, insulation damage, and unexpected outages.

What sets the QHCW2020 apart

• Two-pole configuration: Protects multi-line circuits and ensures simultaneous disconnection of both conductors for safer shutdowns.
• 20A rating: Suitable for a wide range of general branch circuits, motor control circuits, and lighting feeders in industrial, commercial, and OEM settings.
• Versatile applicability: Ideal for use in distribution panels and motor control centers where dependable overcurrent protection and safe operation are critical.
