KD-D: Module with SF6 load break switch and quick release vacuum circuit breaker with integrated protection relay

Application:

Commutation of electrical circuits under normal and emergency conditions; protection of descending feeders. The main advantage of the KD-D module is possibility to quickly replace the switch. It can be very useful for power supply of production processes with a limited stop time.    

Standard equipment:

 three-phase load break switch RV44, class 徘 according to IEC 60265.1, SF6 insulation
 vacuum circuit breaker VA-2 with integrated protection relay and current transformers
 earthing switch with rated making capacity of up to 63 kA interlocked with load breaker switch
 cable support
 door interlock
 panel for capacitive voltage detectors
 low voltage compartment

Options:

Options for the cubicle:

 auxiliary block contacts on load break switch
 auxiliary block contacts on earthing switch
 key interlock on load break switch
 key interlock on earthing switch
 key interlock on both switches
 no door interlock
 motor operation: 24-48-110 V AC/DC, 220 V AC
 capacitive voltage detectors
 socle 200 mm, 300 mm or 400 mm (other dimensions on request)
 floor pans
