Our VCB series of medium voltage Vacuum Circuit-Breakers is used in installations with rated voltages up to 24 kV and with rated currents up to 1250 A; they are constructed using the separate pole technique, each provided with a vacuum interrupter. The operating mechanism is a stored energy type.
The three poles and the operating mechanism are mounted on a single metal frame which, in withdrawable version (both lateral and frontal), is equipped with wheels. It is possible to remotely drive the circuit-breaker by means of proper electrical accessories.
VCB circuit-breaker are characterized by:
- Compactness, quality which makes possible to install them in smaller units than in the past
- Strength, thanks to the accurate design and choice of the employed materials
- Reliability and Reduced need for maintenance
The VCB series of medium voltage vacuum circuit-breakers are sealed pressurized systems and guaranteed for the whole operative life of the product (see IEC 62271-100 Standards).
