• Patented potentiometer setpoint selection
• Trip point indicated on the labeling
• Trip point can be set without energizing the monitored load, adding a large measure of safety
• Two-second delay before contact action upon initial energization allows the output to ignore motor inrush current
• Output is magnetically isolated from the input for safety
• Eliminates insertion losses, no added burden
• No moving components for switching
• No need for periodic maintenance or calibration
• Sensor is powered from the monitored AC circuit
• Fast action contact reacts quicker than RTD, thermocouples, or bimetallic thermal elements

The ASL Series AC Current Sensor provides a current-operated solid-state contact powered by the monitored circuit. The trip point adjustment uses a single-turn potentiometer. This means the installer can set the point where the output changes state when the monitored circuit is not energized by turning the adjustment arrow to the current magnitude needed and installing the sensor over the conductor. Proper installation couldn’t be easier.
