* Indicator is flashing LED which illuminates if the fuse blows. A unique feature of the indicator circuitry is that under some circumstances it is possible to get a fuse failure indication even when the load is disconnected. This is accomplished by capacitively coupling the indicator signal to the system neutral or, in the case of 3 phase circuits, to another phase. The rate of flash of the
indicator is proportional to the line voltage and whether the load is connected or not. Typical flash rates and indicator current
draws are as follows:
120Vac, load
load
220Vac, load

The indicator is optimised for 220Vac operation and may be dim at other voltages. An alternative would be Weidmuller’s VM8
voltage monitor (consult factory for details.)
