Square D Load-Center Circuit Breakers
Series, 1
Tandem 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, so they protect downstream equipment and wiring from overloads and short circuits. 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.
Circuit breakers with ground fault sensitivity will trip if they detect a current leak above 6mA. This minimizes the risk of electric shock to workers and equipment.
Breakthrough current is the maximum current that the circuit breaker can safely stop in the event of a short circuit.
