October 10, 2012
current sensing switch nk technologies asxpAvailable with a user-adjustable set point from 1 to 80A, the NK Technologies ASXP current sensing switch provides low hysteresis and an operating range between 40 and 100 hertz for monitoring single- and 3-phase motors. Used with 24VAC/DC or 120VAC supplies, it comes standard with a solid-core enclosure, LED indicators for trip point contact status and a fixed 2-second delay trip timer. In motor protection applications, the sensor provides electronic proof-of-operation and detects current draw changes in the motor caused by pumps running dry or impending bearing failure.
