Current Sensing Relay, Current Sensing Switch, SZC23-NO-AL-CH AC Normally Open Current Operated Switch, Adjustable AC 0.2-30A Current Monitoring Relays with LED Indicator

• SELF-POWERED DESIGN: The AC current sensing switch does not require external power supply. The action current is 0.2-30A AC and the potentiometer is adjustable. Straight-through structure design, isolation withstand voltage up to 2000 V. Hysteresis less than 1%, can be used under strong magnetic conditions.
• ACCURATE AND TIMELY: This current sensing control is designed to monitor AC current, which not only provides more accurate and timely control, but also greatly simplifies design and reduces costs. There is no limit to the number of times the AC current sensing switch can be opened and closed, and the response speed reaches milliseconds.
• FAST SWITCHING RESPONSE: Adjustable current sensing switches use high power MOS tubes for non-contact electronic switching, with unlimited switching times and millisecond response times.
• LED INDICATOR: The sensor-controlled switch's enclosure is made of self-extinguishing ABS material, and the LED indicator provides a convenient visual indication of the switch's operating status. Compared with traditional transformers, AC current sensing switches have more accurate and timely control, and are simple in design and low cost.
• A WIDE RANGE OF APPLICATIONS: Normally open current sensing switches are suitable for AC current measurement and monitoring, AC motor overload protection, and electronic switches for automatic control systems. Widely used in substations, frequency conversion speed control devices, electric locomotives, street light monitoring and other automation industries that require current monitoring.
