Rhomberg SP430 Phase Sequence/Failure/Asymmetry Relay
BRAND : Rhomberg
P430 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
