ASXP Series Current Sensing Switches are powered versions of our popular current switches with integral time delay. A fixed two-second delay upon initial energization of monitored load minimizes nuisance alarms during startup and operation in motor or heater status applications. After startup a separate 0-20 second delay can be set. For use with 24 VAC/DC or 120 VAC supplies, this high-performance product offers OEM caliber accuracy, precision tolerances, low hysteresis and an operation range between 40 and 100 Hz. Available with status LED and solid-core case as standard.

Safety Interlocks

Current Sensing Switch Applications

• Serves as an electronic proof-of-operation; detects current draw changes in motors when they encounter problems such as pumps running dry or impending 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.

• Factory-set two-second delay on startup eliminates nuisance trips from high inrush or short overload conditions. After startup, a second 0.2-20 second user adjustable delay is available.

Current Sensing Switch Features

• Factory-calibrated trip timer set to 2 seconds to eliminate nuisance alarms due to startup inrush or temporary overcurrent conditions.

• Contact rating of 1 A, up to 120 VAC, provides adequate switching capacity for use with most motor control systems.

• Eliminates need for separate time delay relay.
• Choice of 24 VAC/DC or 120 VAC supply models.
• LED provides indication of trip point contact status.
• Setpoint adjustable from 1-80 A.

• Repeatable performance, precise time delay setpoint,
• constant hysteresis and linear trip point adjustment.

• Accepted worldwide.
