Three-phase mains monitor AC 3(N) 400/230 V, 1 changeover contact , asymmetry adjustable 5-20%
Contact -
Change-over (voltage-free)
Measurements -
87 x 17,5 x 60 mm
Voltage measuring relay for monitoring 3- and 4-wire networks. Monitors phase sequence, phase failure and asymmetry (can also be switched off). Supply voltage is equal to measuring voltage. Detects reverse voltage from motors (reverse voltage safe). Mounting on mounting rail
