Overview
SF1525A — PH Failure & Sequence REL 525VAC, a phase failure / sequence relay by Electro. Listed under Plug-in timing & Monitoring devices on the Electro catalogue at RMS-EM.Africa.
About SF1525A
Phase 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 NPSvoltage 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 voltage corrects itself. The unit will not react to a balanced voltage variation. Features: Relay.
