TRV8 phase monitoring relays

Name: TRV8 phase monitoring relays
Brand: TOSUNLUX

TRV8-05 · versions M265 and M460

127–460 V · IEC 60255-1

TOSUNLUX (Tosun) TRV8 three-phase monitoring relay on an 18 mm module: monitoring of phase sequence and phase loss, overvoltage and undervoltage, and unbalance. It protects motors and equipment against reversed rotation and single-phasing. True RMS measurement.
