Selection Guide

M200-PS13 phase 3 or 4 wire

Typical Applications

The M200-PS1 provides phase and phase sequence / failure protection. Used to ensure the sequence is correct when connecting 3 phase loads. With an incorrect phase sequence the relay will start to de-energise, preventing the starting of incorrectly connected machinery. The relay will also trip if there is a phase loss and can therefore be used as a phase failure relay.

If regenerated voltage voltage is present in the open phase the M200-PB1 or M200-PB2 should be used. The red LED “On” indicates phase sequence incorrect and relay is de-energised.. The green LED “On” indicates phase sequence correct and relay is energised.
