The Square D by Schneider Electric QO 30 The Square D by Schneider Electric QO 30 Amp Two-Pole Circuit Breaker is intended for overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. All QO circuit breakers are equipped with the exclusive Visi-Trip indicator. A circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short. This guide will walk you through the different types of circuit breakers to help you determine which is best for your home's electrical needs. The operating mechanisms of all types of circuit-breakers require servicing, some more frequently than others depending mainly on the amount of energy they have to provide. For the vacuum-circuit breaker the service interval lies between 10,000 and 20,000 operations.
