ASX Series Current Operated Switches are high performance current-operated switches with field-adjustable time delay to help minimize nuisance trips during start-up 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.

ASX SERIES

Current Operated Switches

Features

Adjustable Start-up/Delay Timer

Applications

L Field-adjustable from 0–15 seconds to eliminate nuisance alarms due to start-up inrush or temporary overcurrent conditions. Motor Protection Choice of N.O./N.C. AC or Universal Outputs
L 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.
L Contact ratings of 1.0A @ 240VAC or universal outputs of 0.15A @ 240VAC/VDC (N.O. models) and 0.2A @ 135VAC/VDC (N.C. models) for use with most standard motor control systems.
L Non-intrusive, less expensive to install than differential pressure flow sensors or thermal switches.
L Much quicker response time than Class 10 overload relays. High Inrush or Temporary Overload Current Improved Ease of Installation and Use
L Adjustable start-up/delay timer allows 0–15 second delay to elimi- nate nuisance trips from high inrush or short overload conditions.
L 1.0A AC rating eliminates need for time delay relay.
L Self-powered, split-core models simplify installation .
L Status LED provides visual indication of setpoint trip and contract action. Isolated Alarm System Interfacing Industrial Grade Performance
L Constant hysteresis and linear response characteris- tic enhance setpoint accuracy. Agency Approved
L UL listed, CE pending.
