5A Overcurrent Protection Switch relay

This LC 5A Over-current Protection Sensor module provides relay-based over-current protection for AC signals (0-5A). It uses a current transformer to detect over-current, triggering a relay to activate.

Users can set the over-current critical point by adjusting a potentiometer (clockwise reduces detection current). The module operates on DC12V (<20mA current), with an operating frequency of 20Hz-400Hz. It offers switch signal output (NO, COM, NC ports) and has a max detection wire diameter of 5.2mm.
