Features SP430 monitors 3 Phases only, SP431 monitors 3 Phases and Neutral 11-pin plug-in. Fail-to-safe design. Monitoring on three phase supply. Sensitive to: NPS Voltage, Reverse phase sequence, loss of phase, phase imbalance, phase asymmetry. Insensitive to regenerated EMF. High stability under harmonic distortion Insensitive to balanced supply variations - prevents nuisance tripping Fast response to reversed phase sequence Adjustable NPS sensitivity. Relay ON LED 10A SPDT or 5A DPDT relay output. SP430 Supersedes SP433. Requires optional S3-B 11-pin base. Show more
