The QO series Miniature Circuit Breaker and Switch is available for surface, flush or DIN-rail mounted applications in one, two and three-pole constructions. QOU miniature circuit breakers are used for over-current protection and switching on both AC and DC electrical systems. QOU circuit breaker and switches measure 0.75-inch (19mm) wide per pole. Two- and three-pole circuit breaker is both equipped with an internal crossbar for common tripping of all poles. QOU switches are available in one-pole, 60A and two and three-pole, 60, 100 and 125A construction. Cases for QOU miniature circuit breaker and switch is constructed of a glass-reinforced insulating material that provides high dielectric strength. Current carrying components are isolated from the handle. The handle position indicates whether the circuit breaker is off, on or tripped.
