SF1 Phase Failure/Sequence Relay Economy 4mm Blue Insulated Ring lugPhase Failure Phase Sequence Monitor The Electro 11 pin plug in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient. The SF1 Monitors negative phase sequence (NPS) voltage to detect phase failure, phase reversal, and phase imbalance. The NPS voltage of the unit is fixed at 7%. When any of these faults occur the unit will de energize. The relay will only re energize if the supply
