Line voltage presence detector
24 - 125 V, 6 A | VU-3 - RTP
ARTECHE Group
Three-phase voltage presence surveillance relays, with front signalling and outlet contacts.
VU-3
Connected to warning signal insulators, it detects the presence of three-phase or single phase voltage, indicating both in the front panel and its outlet contacts (4 switchings) which are the phases without voltage. It has three red lamps on its front panel that light up if their is voltage in HV, on pressing the corresponding button.
