Our locally designed, manufactured and distributed KD relay is a comprehensive low voltage Electronic Motor Protection relay designed for conveyor, compressor, crusher, fan and pump motor protection.
Easy to setup via a man-to-machine interface or via computer with free setup software, the user selectable settings are a pleasure to work with.
Dry run or minimum load guards against cavitation in pumps which occurs when there is no media to pump.
Thermal overload, earth insulation lockout, earth leakage and short-circuit protection, along with frequency and power factor measurement, are just some features which, combined with the 2000 event records and 60 last fault records, make this a world class protection relay.
The Result:
The relay protects against phase dry-run or minimum load, guarding against cavitation in pumps which occurs when there is no media to pump and so on
All potential electrical current faults such as overload, running jam (in case of slurry or mixed media pumping)
Protection against motor winding insulation deterioration and water ingress, such as in submersible pumps
Our relays have comprehensive faults and records events records (like voltage spikes) for complete historic operation data and root cause analysis of failures.
