3 Phase Monitoring Relay Wiring Diagram. Do not connect output wires to terminals 7 12 until later step 12. Monitor overvoltages and undervoltages for three phase 3 wire or 4 wire power supplies.
The device operates according to the closed circuit principle g incorrect phase sequence or phase failure. Note due to the wrong connection done the above diagram is an update in the above diagram i have shown the complete method of wiring or connection of phase failure relay diagram with circuit breaker cont actor overload relay push button switches and electric motor however let s talk about this step by step. While each individual application may have its own requirements this diagram showing a three phase monitor relay and motor starter is fairly typical of most installations.
