Current Sensing Relay AC Current Sensing Switch 0-30A Normally Open Current Sensor Monitoring Relay (M3050)

This AC Current Sensing Relay is designed to deliver precise monitoring and control for a wide range of industrial and electrical applications. With a measurement accuracy of less than 1% and an ultra fast response time of just 1 millisecond, this device ensures reliable detection of current flow from 0 to 30 amps. Its normally open configuration makes it ideal for use as a trigger or switch in automated systems, pumps, conveyors, and HVAC equipment. Crafted from durable ABS material, the sensor is built to withstand demanding environments. With a compact footprint of 2.5 by 0.98 by 1.85 inches, it integrates easily into existing panels or enclosures using the included mounting screws. The digital AC output provides a clean signal for seamless connection to controllers, alarms, or other monitoring equipment. This relay is rated for continuous operation up to 55 degrees Celsius and is not intended for smart home integration, making it a focused, robust choice for professional and commercial settings. Whether you are monitoring motor startup, detecting load status, or automating safety cutoffs, this sensor offers consistent, repeatable performance without unnecessary complexity.
