NK ASX-NCU-SP - Current Sensing Switch, ASX Series

ASX series
AC current sensor
Output type = Normally Closed, 0.2 A @ 135 VAC/DC
Case style = Split Core

ASX Series Current Sensing Switches are high-performance current sensing switches with a field-adjustable time delay to help minimize nuisance trips during startup and operation. Designed for motor status applications where setpoint accuracy and repeatability are critical, the ASX Series offers a linear setpoint characteristic and constant hysteresis. Standard features include self-powering, jumper-selectable ranges and a choice of outputs and cases.

Isolated Alarm System Interfacing

Current Sensing Switch Applications

Motor Protection

Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure.
Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches.
Much quicker response time than Class 10 overload switches.

High Inrush or Temporary Overload Current

Adjustable startup/delay timer allows 0.2-15 second delay to eliminate nuisance trips from high inrush or short overload conditions.

Current Sensing Switch Features

Adjustable Startup/Delay Timer

Field-adjustable from 0.12 to 15 seconds to eliminate nuisance alarms due to startup inrush or temporary overcurrent conditions.

Choice of N.O./N.C. AC or Universal Outputs

Contact ratings of 1.0 A @ 240 VAC or universal outputs of 0.15 A @ 240 VAC/DC (N.O. models) and 0.2 A @ 135 VAC/DC (N.C. models) for use with most standard motor control systems.

Improved Ease of Installation and Use

1.0 A AC rating eliminates the need for time delay relay.
Self-powered, split-core models simplify installation.
Status LED provides visual indication of setpoint trip and contact action.

Industrial Grade Performance

Constant hysteresis, linear response characteristics enhance setpoint accuracy.

UL/cUL and CE Approved

Accepted worldwide.
