QN Breakers

The circuit breaker family QN offers the latest in thermal-magnetic circuit breaker design. In this design the handle returns to the center (trip) position similar to our other thermal trip circuit breakers. With a thermal sensing design and blow-off contacts, this circuit breaker offers a higher level of protection because the circuit breaker trip time adjusts to the temperature of the attached wire, while keeping the magnetic characteristic that assures a quick trip under high current conditions.
