Voltage and phase measuring and monitoring relay
450 V, 2 VA | E18 F60 series
FIBER
Multi-voltage
Microcontroller electronic device, with supply voltage from 200 to 450Vac 50 and 60Hz
Designed to monitor the correct sequence (R-S-T) in a three phase mains
It also controls the presence of all phases and the value of supplying voltage and operates, de-energizing the output relay, when one of three phases drops or when voltage goes down the fixed threshold value
The housing is made by glass reinforced polycarbonate, suitable to be mounted on DIN rail 35 mm (EN50022)
A signalling LED indicates the correct sequence of the three phases and the output relay ON
