Product Description

Why we choose SF6 gas circuit breaker???
The SF6 gas circuit breaker is best choice for switching of low inductive load or capacitive load!

General

HR4 type high voltage indoor SF6 gas circuit breaker with two installation way by drawable/Fixed. which is widely application for three-phase AC power system of rated voltage from 3.3kV up to 36kV at frequency 50/60Hz, especially using for power plant, transformer substation, petrol chemical industry, metallurgy, manufacturing industry, airport, residential area, etc..

Its high performance switchgear which will reduce over-voltage and harmonic impulse at max for by a normal or fault breaking or making. 

Its easy for interchange for VD4,SF1,HD4 type switchgear like type KYN28 or AMS, ABB type ZS1 series, etc.

This circuit breaker is follow per standards like:

IEC62271-100 AC high voltage circuit breaker,

GB1984-2003 AC high voltage circuit breaker

JB3855 3.6-40.5Kv indoor AC High voltage circuit breaker

DL/T403 Specification of 12-40.5kV indoor High voltage vacuum circuit breaker.
