Description
NK ASX-NCAC-FT – Current Sensing Switch, ASX Series
- ASX series
- AC current sensor
- Output type = Normally Closed, 1 A @ 240 VAC
- Case style = Solid 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.
