Phase Sequence Relay Wiring Diagram

Can be accomplished by using the diagram below.

Phase sequence relay wiring diagram.

The model 153 reverse phase relay is designed to. How to wire a phase sequence. The k8ak ph1 output contacts are normally operative. 153 if the relay contacts do not transfer when power is.

The pahi includes a true time delay. Wiring example timing charts phase sequence and phase loss operation diagram note. Phase 1 l2 l4. Phase loss cannot be detected on the load side because.

Wiring diagram book a1 15 b1 b2 16 18 b3 a2 b1 b3 15 supply voltage 16 18 l m h 2 levels b2 l1 f u 1 460 v f u 2. If a phase failure occurs on l2 or l3 the shunt trip coil will draw power from l1 through the control relay cr contacts and phase failure relay contacts which will c hange state upon detecting a phase failure. Check all fuses and verify that all wiring connections are correct. Must watch this if you want to know how to wire phase failure relay phase monotoring relay and a direct on line starter.

Should problems persist contact the factory for assistance. Application diagram 8 l1 6 5 n l2 l3 line l3 l2 l1 l1 l2 l3 m socket mounting 1 6 7 2 a1 l1 l2 l1 l1 l2 l2 l3 l3 l3 a2 11 10 9 8. How to wire a phase failure relay device phase sequence. How to wire a phase failure device.

Phase 2 l1 l2 l3. Wiring diagram for additional information. The pama pami are 4 wire relays for sequence control and phase and neutral monitoring. If a phase failure occurs on l1 the control relay cr c ontacts change state.

Like subscribe and don t skip the. The paha pahi are 3 wire relays for sequence control and phase monitoring. The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are also used to provide power. 4 wire 3 phase line markings l1 l2 l1 l3.
