Air Circuit Breakers - ACBs

Circuit breakers automatically disconnect power when a short circuit fault is detected downstream or when the circuit becomes overloaded, exceeding the electrical cable current capacity. Air Circuit Breakers (ACB) protect circuits between 630 amps to 6300 amps and are typically used as the main breaker in a large switchboard or to power large equipment directly. Ideal for large buildings, manufacturing sites & infrastructure projects where a high demand for low voltage power is required.
