Siemens Monitoring Relay, DIN Rail Mounting, Screw Terminals - 3RN2 Series - 3RN2010-1CW30


Keep your motor running smoothly with this monitoring relay from Siemens. It's a NO/NC device that uses a thermistor to continuously check the current flowing to the motor. By keeping a watchful eye out for faults such as overload or phase loss, it knows when to shut off the motor if necessary to prevent damage. Thanks to a voltage sensing range of 24 to 240V DC, this is a versatile option. You can easily snap and screw it onto a DIN rail to help you build an organised system in applications ranging from conveyor belts to machine tools and fans.

• LEDs enable you to easily check on the status

• Surge voltage resistance rating of 4kV means it can stand up to high power surges

• Screw terminals help you make quick and easy electrical connections

• Operating temperature range of -25°C to +60 °C makes it suitable for harsh industrial environments

What's a thermistor sensor?


A thermistor sensor is a temperature sensor made of sintered semiconductor material. If its temperature changes by even a small amount, its resistance will change by a large amount, making it a sensitive means of monitoring temperature and shutting off a circuit before it gets too hot.
