Product Introduction

It adopts combined design, the floor-standing structure of circuit breaker handcart, equipped with insulated vacuum circuit breaker, which has the characteristics of good interchangeability and convenient replacement;

The handcart frame is equipped with a screw nut propulsion mechanism and an overrunning clutch, which can move easily and prevent damage due to misoperation; all operations are carried out in the closed state;

Service environment:

a) Air temperature: -25℃~+40℃

b) Humidity: Monthly average humidity 95%; Daily average humidity 90%.

c) Altitude2500m

d) Ambient air not apparently polluted by corrosive and flammable gas, vapor, etc.

e) No frequent violent shake
