AC VOLTAGE INDICATOR / MONITOR / WINDOW COMPARATOR OVER / UNDER CURRENT PROTECTION
This device provides OVER and / or UNDER current protection. The display may be scaled to any value from 5 to 5000 and the decimal pointer set to any position. This allows the device to be configured for any primary CT current with up to 3 decimal places. Each relay is controlled via separate upper, lower and hysteresis set-points. The relays may therefore be configured for both over and / or under, or one for over and the other for under current protection. Programmable ‘start-up’ and ‘reaction’ delays are included.
