Siemens Monitoring Relay, SPDT Contact, DIN Rail Mount, 0 V AC Supply, Screw Terminals, 40 ms Delay, 3RN2010-1CW30

Siemens 3RN2010-1CW30 monitoring relay is a high-quality, SPDT contact relay mounted on DIN rail designed to provide precise motor monitoring and protection. It continuously monitors the current flow to motors using an integrated thermistor sensor, which changes resistance with temperature, enabling early detection of overload or phase loss conditions to prevent motor damage.

This relay operates with a supply voltage of 0 V AC and offers a fast time delay of 40 milliseconds for prompt fault response. The screw terminal type facilitates robust and convenient wiring in control panels.

The device features a surge voltage resistance of 4 kV, ensuring durability under high voltage transients. Its IP20 rating confirms protection from solid foreign objects, making it suitable for various industrial environments.

Operating reliably across a wide temperature range from -25°C to +60°C, this relay is ideal for harsh industrial applications including conveyor systems, machine tools, and fan controls, enabling efficient monitoring and fault detection.

Compact and easy to install, the relay measures 100 mm in height, 91.6 mm in length, and 17.5 mm in width, optimizing space within control cabinets. Compliant with EAC standards, it ensures product safety and regulatory adherence.

Provides continuous current monitoring via thermistor sensor. Quick and secure connections with screw terminals. Fast 40 ms response time delay. High surge voltage resistance rating of 4 kV. Wide operating temperature range from -25°C to +60°C.

Compact DIN rail mount design for organized installations. Complies with EAC standards for quality assurance.
