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.
