Schneider Electric QOB220VH U Circuit Breaker

Schneider Electric's Square D QOB220VH is a 20-amp, two-pole bolt-on miniature circuit breaker rated for 120/240 VAC, delivering a 22,000-amp interrupting capacity (22 kAIC) at 240 VAC. Part of the QOB family, this thermal-magnetic protection device is designed for bolt-on installation in compatible QOB panelboards and load centers, providing reliable disconnection for both hot legs on 240-volt circuits. It supports conductors typically sized in the 14–8 AWG range, enabling straightforward wiring with standard residential or light commercial feeders. The 2-pole configuration ensures simultaneous trip of both poles, helping meet safety requirements for multi-wire branch circuits and 240V loads, while the bolt-on mounting simplifies field replacement in suitable enclosures. This model is commonly used wherever a dedicated 240V, 20A protective device is needed in Schneider Electric’s QOB systems, offering a compact, high interrupting rating suitable for demanding breakers in tight electrical layouts.
