Square D Load-Center Circuit Breakers
QOB Series, 1 Pole
QOB Series, 2 Pole
QOB Series, 3 Pole
Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series. They meet UL 489 requirements for branch circuit protection. All are thermal/magnetic—breakers trip when heat is generated by sustained, low-level overload current, but will trip quickly when the magnetic field in the coil senses a high-current short circuit.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
