mk-05 phase failure and sequence relay

MK 05 phase failure and sequence relay

MK-05, MKC-05, MK-06, and MKC-06 phase failure devices serve the following protection features.
1. Phase failure

2. Phase sequence

3.PTC Protection (only available in MK-05P,MKC-05P,MKC-06P,MK-06P Versions)

4.Voltage unbalance(Both unbalance and delay adjustable)

5. Insufficient supply
