Air circuit breakers

Air Circuit Breakers

The unique “Double Break” main contact system ensures extremely fast interruption of short circuit currents and substantially reduces main contact wear. The internally symmetrical “Double Break” structure allow reverse power connection. This is the only ACB with this facility in India

Very fast interruption by Double Break system

No extra arc space required vertical stacking permitted

The TemPower2 ACB dissipates all arc energy within its unique

“Double Break”

arc chamber. This internal energy dissipation  allows the clearance distance between  the ACB  and  nearby earthed metal to be zero  minimizing switchboard height and costs.
