UL Listed (UL 489) and CSA certified (22.2 No. 5.1) and have an additional short time delay pick up range for selectivity in energy distribution networks. The time delay response is adjustable form 0 to 1000 milliseconds.
Features of the ZMV(A) trip modules used for selectivity:
- Fixed (ZMVA...) or adjustable (ZMV...) long time response current
- Adjustable time delay (2 - 4 - 6 - 8 - 10 - 12 - 14 - 17 - 20 seconds) for current levels at 6 times the long time response current (Ir)
- Long time response current can be disconnected
- Adjustable time delay (0 - 10 - 50 - 100 - 150 - 200 - 300 - 500 - 750 - 100 ms) pick up setting
- Adjustable instantaneous pick up response
