Product Details
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.
