Bolt On Miniature Circuit Breakers

Square D QOB Series miniature circuit breakers (MCB) safeguard sensitive electrical devices against overloading or short-circuiting. They are ideal for broad-area lighting applications which require lamps with high inrush currents. These bolt-on circuit breakers feature a trip handle mechanism for visual indication of breaker's status and quick-make, quick break action to open all the poles simultaneously when tripped. The breakers are equipped with screw clamp or lug terminals for secure connection and bolt-on mounting for installation in both vertical & horizontal orientations. They are offered in AFCI, GFCI, HIC, PowerLink, shunt trip, high intensity discharge & standard breaker options and are available in current ratings ranging from 10 to 150A on Raptor Supplies.
