DR 61 Phase-Sequence Relay
The phase-sequence relay DR61 is used to prevent the starting of three-phase machines whose phase sequence has been wrongly connected to the mains.
If the phase sequence is correctly connected to the mains, the start signal is relayed. If the phase sequence is wrongly connected to the mains, the start signal is not relayed.
