NK Technologies' AS1 Series Compact Case Current Sensing Switch monitors energized circuits
NK Technologies' AS1 Series Compact Case Current Sensing Switch is designed to enable users to monitor an energized circuit in tight spaces. The ring design slips onto a conductor to detect currents as low as 0.5A with a single conductor pass.
The AS1 has 24-inch leads that can be connected directly to controller input terminals or brought out to a terminal block to facilitate remote operation. The contact can control either AC or DC circuits to 120 volts, with a maximum load capacity of 150mA.
This current sensing switch is powered directly from the monitored circuit to monitor and report electric motor load status, identify open heater circuit connections and independently verify that a load is energized. It is also useful for confirming current flow to and operation of critical lighting and other equipment. The AS1 is rated for use in ambient temperatures ranging from -4 to 122° F (-20 to 50° C).
