Air Circuit Breakers are designed as the main breaker to protect electrical equipment against overload currents, short circuit currents, and ground faults. They are suitable for use in smart building distribution systems in power plants, factories, mines, and especially in buildings expected to draw high loads.
Sigma Air Circuit Breakers are produced in accordance with TS EN 60947-2 standards and CE norms, available in both fixed and withdrawable types as needed. With a wide range of accessories, functions such as remote opening, closing, and low voltage tripping can be performed using a combination of low voltage coil, closing coil, and motor mechanism.
4 different functions of Air Circuit Breakers
- Opening and closing the circuit
-Protection against overloads
-Protection against short circuit currents
-Ground fault protection
