Current Sensing Relay AC Current Sensing Switch 0-30A Normally Open Current Sensor Monitoring Relay (M3080)

This AC Current Sensing Relay is designed to provide reliable and accurate current monitoring for industrial and commercial electrical systems. It detects the presence or absence of AC current in a conductor and triggers a normally open switching output when current exceeds a preset threshold, making it ideal for load monitoring, motor control, lighting management, and automation applications. Featuring a detection range of 0 to 30 amps with a measurement accuracy of less than one percent, this sensor offers consistent performance for both low and moderate current loads. The response time of just one millisecond ensures rapid switching, allowing for real-time monitoring and control in time-sensitive environments. The digital AC output simplifies integration with PLCs, contactors, and other control devices. Constructed from durable ABS material, the relay is built to withstand demanding conditions with an upper operating temperature rating of 55 degrees Celsius. The compact form factor, measuring 2.5 by 0.98 by 1.85 inches, allows for easy installation in tight spaces, while the screw mount design provides secure and straightforward attachment to panels or equipment. Two mounting screws are included for convenience. This device is suitable for a wide range of applications, including pump control, conveyor belt monitoring, heater failure detection, and automated energy management. It operates without the need for smart home integration, focusing purely on reliable industrial-grade current sensing. The normally open configuration ensures that the circuit remains off until the sensed current reaches the activation point, offering clear status indication and safe system operation. With its high precision, fast response, and durable build, this current sensing relay is a practical solution for professionals seeking dependable current monitoring without unnecessary complexity. It is a standalone unit designed for direct installation in control panels, distribution boxes, or machinery enclosures, supporting efficient and safe electrical system management.
