IEC SF6 Mechanical Circuit Breaker HD4

HD4 circuit-breakers are available in fixed or withdrawable versions. The withdrawable version is available for CBF fixed parts and CBE and PowerCube enclosures, UniSafe and UniGear type ZS1 switchgear. HD4 circuit-breakers are used in power distribution to control and protect lines, transformer and distribution substations, motors, transformers, capacitor banks, etc. They are also highly suitable for retrofitting, where the insulating materials of circuits may be sensitive to dielectric stresses.

Fields of Application

HD4 circuit-breakers are used in power distribution to control and protect lines, transformer and distribution substations, motors, transformers, capacitor banks, etc.

Thanks to the SF6 autopuffer breaking technique, the HD4 circuit-breakers do not generate operating overvoltages, and are therefore also highly suitable for retrofitting, upgrading and enlarging older installations where the motor, cable, etc. insulating materials may be particularly sensitive to dielectric stresses.
