1 3 /2 3.0 7 3 /8 Voltage Sensitive Relays WILMAR Protective Relays WUV/WOV Series Function: 27/59 ANSI/IEEE C37.90-1978 UL file No. E58048 CSA file No. LR61158 TERMINAL STRIPS 6 - 32 SCREWS Voltage sensitive relays are available for both AC and DC applications for over/undervoltage protection. Combination over/undervoltage relays provide bandpass capabilities. AC relays are either single or three-phase type. Three phase models are de- signed to sense the average of the three phases or the highest single phase. Voltage trip points are screwdriver adjustable, and operation is time-de- layed so that momentary voltage transients will not cause nuisance tripping.
