Product Description

Type LW24 outdoor H.V A.C dead tank SF6 with voltage range from 40.5 to 145

Introduction:
This a new kind of circuit breaker with self-blast interrupter and spring operating mechanism. The lastest achieve-arc gas-blast pressure
adapter for breaking current extinguishing principle is employed, most of the energy for the breaking of short-circuit current is required by the
arc itself. Therefore, the demand for operating power is reduced significanlty. The three phase interrupters are placed inside three metal
enclosures respectively.

The circuit breaker can be machanically three phase gang-operated, from both a remote electrical control and a local manual control. Type
CT20-II spring operating mechanism, provided with the product, is a mechanism with low operating power, minimun maintenance work need
and high realiabiity.
