Product Description
Brief Description
LW35S-252 Circuit Breaker adopts self-energizing interrupter and CYT hydraulic operating mechanism, which have the advantages of simple structure, stable and reliable performance, etc., to realize three-pole-gang operation. It fills the domestic gap of professional market and meets urgent requirements of power system.
Main Features
1 The interrupter adopts advanced self-energizing arc-extinguished principle, can make use of the energy generated from arc itself to break fault current, so as to realize a small operating energy with high mechanical reliability.
2 The circuit breaker is equipped with CYT hydraulic operating mechanism, dynamic sealing system adopts advanced Glyd ring, Step seal, etc., which reduces the leakage and starting friction.
3 The mechanism uses imported control valve, with the advantages of fast operating speed, short opening time, reliable anti-slow-opening function in case of pressure loss.
