Square D Load-Center Circuit Breakers

Match these circuit breakers to Square D breaker boxes or panel boards of the same manufacturer series. Because they are thermal-magnetic, these breakers trip two different ways. They either trip when heat is generated by sustained low-level overload current or quickly when the magnetic coil senses a high-current short circuit.
