IEC SF6 Mechanical Circuit Breaker HD4/R

HD4/R are used in secondary MV distribution and in MV/LV transformer substations. They are available in fixed version with right-hand side operating mechanism. Circuit-breakers with rated voltage up to 24 kV can be fitted with current sensors and PR521 overcurrent release and can be used in unmanned substations without auxiliary power supply.

Ratings
Rated voltage (kV)	12 - 36

Rated current (A)	630 - 1250

Rated breaking current (kA)	12,5 - 25

Fields of application

The circuit-breakers in the HD4/R series are used in all applications for medium voltage secondary distribution and in MV/LV transformer substations in factories, workshops in the industrial sector in general, and in the service sector.

Thanks to application (on request) of the PR521 self-supplied microprocessor-based overcurrent release, HD4/R circuit-breakers are suitable for use in unmanned MV/LV transformer substations without auxiliary power supply.
