Air Circuit Breakers are designed as main breaker to protect electrical equipment against overload currents, short circuit currents and ground faults. It is suitable for use in smart building distribution systems in power plants, factories, mines and especially in buildings that are expected to draw high loads.
Sigma Air Circuit Breakers are produced as fixed type or withdrawable type according to the need in accordance with TS EN 60947-2 standard and CE norms. If desired, functions such as remote opening, closing and opening at low voltage can be performed with the combination of low voltage coil, low voltage coil, closing coil and motor mechanism, thanks to the wide range of accessories available.
4 different functions of Air Circuit Breakers
• Opening and closing the circuit
Protection against overloads
Protection against short circuit currents
Ground fault protection
• 3 and 4 pole product range
• 80kA, 100 and 120kA short circuit breaking capacity
• Rated current from 630A to 6300A
• 1000 VAC rated insulation voltage
• Possibility of maintenance and repair without cutting off system power with drawer types
• Possibility to monitor phase voltages and phase currents on the LCD screen
• Showing phase information where the error occurred
