Current Window Comparator The Electro 11 pin plug-in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient. The WA5 is a precise UNDER / OVER current window monitoring relay. The unit can be ordered in many AC / DC current ranges, making it ideal for many current monitoring applications. The over and under set points can be adjusted with separate potentiometers. The unit also incorporates a latch facility to prevent undetected failures. For applications which necessitate a CT, all units are supplied with a terminating resistor to prevent open circuit.
