NETWORK MONITORING RELAY 1-PHASE/3-PHASE

- Measuring input: Un=400/230VAC
- Terminals (Ν)-L1-L2-L3
- Monitoring functions: phase sequence & failure,
  undervoltage monitoring (UNDER), undervoltage monitoring & monitoring of phase sequence (UNDER+SEQ),
 monitoring the window between Min and Max (WIN), monitoring the window between Min and Max & monitoring of phase sequence (WIN+SEQ)
- Adjustable: delay - max - min - function
- Tripping delay: 0.1s - 10s
- Switching threshold: Max 80% to 130% Un - Min: 70% to 120% Un
- Rated voltage: 3(Ν)-400/230VAC -30% to +30%
- Output: one change-over contact 1C/O, 5Α/250VAC
- LED operation indicators (SEQ, MAX, MIN, R)
- Width: 17.5mm

Can also be used in a single-phase network,
by bridging the terminals of the 3 phases
