Power Circuit Breakers

for safety and protection

Air Circuit Breakers  
  The TemPower 2 ACB is extremely reliable in service.

All models have a short-time withstand rating equal to the service breaking capacity. This guarantees discrimination, or selectivity, without further calculation because it allows short-circuit protection to be time-delayed, even at the maximum prospective short-circuit current.
