Compact Din rail or foot mounted “CT” style AC current proving switches, the sensing range (set point) being adjustable 0.2-20 Amps or 2-200 Amps. On current flowing of at least 0.2 Amps or 1 Amp the power LED will be illuminated, on current flowing in excess of the adjustable set point the status LED will be illuminated denoting the Normally Open output is closed. On current falling below the set point less a nominal 2% hysteresis the output will open and the status LED will extinguish and the power LED will illuminate, if the current has fallen to zero both the power and status LED’s will extinguish.

The FOX.CS-xxx current switch is self powered yet benefits from a volt free output Normally Open switch. The maximum switching capability is 30VAC/DC 0.5 Amps.

It is also possible for low current sensing, to pass the conductor to be measured multiple times through the CT (referred to as turns). For example; 2 turns will give a sensing range of 0.1-10 Amps or 1-100 Amps, 4 turns a sensing range of 0.05-5 Amps or 0.5-50 Amps.
