QO2020

The Schneider Electric QO2020 circuit breaker is engineered as a tandem-style miniature circuit breaker. It provides a maximum current capacity of 20 amperes, efficiently managing electrical flow for protection. Rated for operation at both 120 or 240 volts AC, it is versatile for various electrical applications. The design includes two independent single-pole circuits, allowing for simplified integration in tight spaces. With a robust short-circuit withstand capability of up to 10,000 amperes, this breaker guarantees reliable protection against overload conditions.

The QO2020 is mounted using a plug-in installation method, securing it conveniently within the electrical panel. It occupies only a single breaker slot, optimizing space while ensuring effective functionality. Additionally, the breaker supports a range of wire sizes from AWG 14 to AWG 8, thereby accommodating copper and aluminum wires through its box lug terminal connection type.

When setting up, it is important to adhere to the recommended torque setting of 24.8 lbf.in (2.8 N.m) for optimal performance. The physical dimensions of the QO2020 are 3.2 inches in height, 0.7 inches in width, and 2.9 inches in depth, with a net weight of 0.3 lbs (0.136 kg).

It is rated to operate safely in ambient temperatures up to 104°F (40°C), making it suitable for a variety of conditions. The circuit breaker also provides essential fault protection against overloads and short circuits, contributing to the overall safety and reliability of the electrical system.
