NK AS3-CCDC-FF – Current Sensing Switch; Dual, 1 N.O., 1 N.C. Solid State, 0.15 A @ 30 VDC, Solid-core, Front Terminal, Standard

NK AS3-CCDC-FF – Current Sensing Switch; Dual, 1 N.O., 1 N.C. Solid State, 0.15 A @ 30 VDC, Solid-core, Front Terminal, Standard

• AS3 Series
• Current sensing switch
• Output Rating = 1 N.O., 1 N.C. Solid State, 0.15 A @ 30 VDC
• Case Style = Solid-core, front terminal
• Options = Standard

AS3 Series Current Sensing Switches provide the same dependable indication of status offered by the AS1, but with the added benefit of increased setpoint accuracy. A choice of three, jumper-selectable input ranges allows the AS3 to be tailored to an application, providing more precise control through improved setpoint resolution. Self-powering, isolated solid-state outputs, 1-6 A, 6-40 A and 40-200 A input ranges, and a choice of split- or solid-core case are standard.

Note: -15 Model must be mounted on a metal surface 144 sq. in. minimum in size to achieve a 15 amp rating.
