Air Circuit Breakers ACB

5 Reasons to use TemPower 2 ACBs

1. Patented High Performance 5000A and 6300A ACBs The air circuit breaker interrupts the current at two points on the line side while dissipating heat from contacts or terminals by efficient air convection through pressure valve.
2 Double opening and closing coils Double Opening and Closing Coils provides extended control system redundancy to an ACB. Double coils allow designers to implement back-up tripping and closing systems. It provides the end-user with ultimate reliability on critical UPS circuits connected to critical loads.
3. Fast interruption by unique “Double Break” system* The unique “DoubleBreak” main contact system ensures extremely fast interruption of short circuit currents and substantially reduces main contact wear. The internally symmetrical “DoubleBreak” structure means the moving contact is isolated from the supply voltage even when the ACB is reverse connected. TemPower 2 ACBs up to 4000A use DoubleBreak technology.
4. Easy Maintenance The unique design of TemPower 2 incorporates its isolating clusters and main contacts on the ACB body. The main contacts and isolating clusters may be maintained without having to isolate the switchboard.
5. Replacement of the main contacts* The fixed and moving contacts can easily be replaced in the field, thus prolonging the life on the circuit breaker. Changing each pole takes around 15 minutes. *Not available on AR6
