- Under voltage monitoring
- Monitors own three phase, 3-wire supply
- Detects incorrect phase sequence and phase loss
- Fixed Trip levels and Time delay
- SPDT Relay output
- 17.5mm wide, DIN Rail mount
- UL Listed
The product monitors it’s own three-phase supply and for the output relay to energise, all phases must be present, the phase sequence correct and the phase to phase voltages above the fixed trip level. If any of these conditions are not met, the relay will de-energise.
