Current Switches

Monitor AC or DC current to detect load status, undercurrent or overcurrent. Model-dependent ranges extend from 3 mA to 1600 A. Choose solid-core or split-core housings and fixed, adjustable or self-calibrating setpoints. Selected models offer time delays, digital setpoint displays or a combined switch and analog output.
