The current transformer in the monitoring circuit does not only supply the input signal but also the very low power consumption of the Monitor.

Zero current monitors are generally used to monitor circuits for wire breakage. The E-T-A Zero Current Monitor E-1076-SR may also be used to switch on an elapsed-hour meter.

In this case the opto decoupled triac or transistor output will provide the control signal for the meter as soon as the load to be monitored is switched on.

The E-T-A Zero Current Monitor is supplied in a compact moulded housing with screw terminals for mounting on DIN EN 50022 and DIN EN 50035 rails.
