The Schneider Electric QO220EPD is a miniature circuit breaker specifically crafted to meet essential protection requirements in electrical circuits. With a nominal current rating of 20 A, this device is versatile, operating within a rated voltage range of 120 to 240 V AC, and can also be serviced at 120 V AC. The breaker consists of two poles and is ideal for applications requiring reliable power management.
Critical to its design is the ground-fault protection that initiates a residual-current trip at 30 mA, providing vital safety measures against electrical hazards. The unit has a robust breaking capacity of 10 kA at 120/240 V AC, making it suitable for general applications.
Installation is simplified due to its plug-on mounting format that eases setup in various electrical panels. Terminal connections are made through pressure-plate interfaces, which enhance reliability and ensure secure electrical continuity. Regarding physical dimensions, the QO220EPD occupies two breaker spaces in the panel. Its overall measurements are 4.12 inches (105 mm) in height, 1.5 inches (38 mm) in width, and 2.91 inches (74 mm) in depth. The wire gauge compatibility for this circuit breaker includes copper wires ranging from AWG 14 to 8 and aluminum wires from AWG 12 to 8. Proper torque settings are also specified at 35.4 lbf·in (4 N·m) to maintain stability in connections.
