Square D QOU Series circuit breakers are designed for overcurrent protection and switching On AC & DC electrical systems. They feature a case made of glass-reinforced insulating material to offer high dielectric strength and come with slotted box-type lugs which are UL listed and CSA certified to accept solid / stranded, aluminium or copper conductors. The shunt trip mechanism trips the circuit breaker from a remote location, using a trip coil energised from a separate electrical source like a remote. QOU Series circuit breakers are available in a maximum current rating of 100A on Raptor Supplies.
