BQD220 - 20Amp Circuit Breaker

BQD220 - 20Amp Circuit Breaker

The Siemens BQD220 is a 20-amp, 2-pole circuit breaker used in 480VAC panelboard applications. It's designed to open the circuit when an overload or short circuit occurs, helping protect your wiring and connected equipment from damage. You'll commonly see this breaker used in commercial buildings, industrial facilities, schools, and other environments where dependable branch circuit protection is required.

Like other breakers in the Siemens BQD series, the BQD220 uses a thermal magnetic trip mechanism. The thermal portion responds to overload conditions that develop gradually, while the magnetic trip reacts quickly during short-circuit events.

The breaker features a molded case construction and panelboard mounting configuration, making it suitable for a wide range of distribution and control applications. With a 14 kAIC interrupting rating, the BQD220 is built for many common commercial and industrial installations where reliable overcurrent protection is needed.
