ACB
Supplied by
- Schneider MasterPact MTZ air circuit breakers protecting systems up to 6300 A, with high short-circuit withstand and full selectivity. Micrologic electronic control units add power and energy metering, earth-fault and residual protection, and communication to the building management system through the breaker itself.
- Sit at the incomer and bus-tie positions of main LV switchboards in towers, hospitals, airports and industrial plant. What distinguishes an ACB at this level is short-time withstand: it can hold a fault current for a defined delay instead of tripping instantly, which is what lets everything downstream clear its own faults first and keeps the rest of the building live during a fault on one floor.
