KD-D-500: Module with SF6 load break switch and draw-out vacuum circuit breaker with integrated protection relay


Commutation of electrical circuits under normal and emergency conditions; protection of descending feeders. The main advantage of the KD-D-500 module is the 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 plug-in contacts
 earthing switch with rated making capacity of up to 63 kA interlocked with load breaker switch RV 44
 current transformers
 cable support
 door interlock
 panel for capacitive voltage detectors
 low voltage compartment


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
 socle 200 mm, 300 mm or 400 mm (other dimensions on request)
 floor pans
 press button for switch-disconnector
 remote control for switch-disconnector
 current transformers
Please consult us for other options and dimensions.


Options for the vacuum circuit breaker:
 voltage detectors
 automatic closing
 shunt trip
 delay/direct under voltage release
 auxiliary block contacts
 error contact
 power unit for protection relay RP-600
 commutation device counter
 press button for vacuum circuit breaker
 remote control for vacuum circuit breaker
 automatic closing
