Indoor Vacuum Circuit Breaker 35 kV Series VBC-35 for Reliable Electrical Protection

Vacuum circuit breakers of VBTS-35 series are designed for switching of AC electric circuits with rated voltage 35 kV and frequency 50(60) Hz in normal and emergency modes of operation in systems with isolated or partially grounded neutral. VBTS-35 - switches of internal installation, specially designed for use at metallurgical plants. They are characterised by increased switching life for this voltage class. Design features VBTS-35 switches are switching devices, three poles of which are mounted on a common frame and controlled by an electromagnetic actuator installed inside the frame. The vacuum chamber is enclosed in a housing made of epoxy compound.
