SIRIUS 3UG4 and 3RR2 monitoring relays facilitate the monitoring of various electrical and mechanical parameters in the feeder and reliable system protection against damage. The relays can be mounted in stand-alone assembly (3UG4); alternatively, the 3RR2 current monitoring relay can be directly integrated in the feeder by easy plug-on mounting on SIRIUS 3RT2 contactors. SIRIUS monitoring relays not only feature freely parameterizable threshold values and manifold adjustment options, but also provide conclusive diagnostics and are even able to correct an incorrect phase sequence autonomously. Numerous versions are also available with IO-Link interface for connection to the control.

There are monitoring relays available for the following applications:. For protection against overheating Thermistor motor protection relays provide decisive benefits in cases in which current-dependent protection using either a circuit breaker or an overload relay is not the perfect solution.
In specific cases, overheating can occur without being detected by the thermal image in the circuit breaker or overload relay, for example in the case of heavy starting, operation with frequency converters, strong braking operations or restricted ventilation. The SIRIUS 3RN2 thermistor motor protection relays protect the motor reliably against overheating as they monitor the winding temperature of motors directly.

The temperature of solid, liquid and gaseous media represents the most frequently measured parameter in industrial applications. Not least because of this fact do SIRIUS temperature monitoring relays serve as the ideal devices for system protection. They monitor process temperatures just as reliably as the temperature inside control cabinets or motors – if required even with up to three sensors at the same time. Analog and digital versions are available to suit various requirements. Numerous versions are also available with IO-Link interface for connection to the control. Find out more about IO-Link:. Analog and digital versions are available:.

3RN1 thermistor motor protection relays offer substantial advantages wherever current-dependent protection with circuit-breakers or overload relays is simply not enough: in certain situations overheating of a motor may occur, which won't be detected by the thermal image in the circuit breakers or overload relays. Applications. Heavy starting (e.g.
Centrifuges). Frequency converters.
Frequent switching. Impeded cooling, e.g. Due to soiled environment (paper and textile industry, cement works). Braking operations. 'Warning and tripping' function by using two sensor circuits with different response temperatures in order to be able to react before shutdown (e.g.
Switch in additional cooling, reduce load). Multimotor protection with a single device, e.g. For conveyor lines where several motors need to be switched off simultaneously.
Advantages at a glance. One device covers all motor powers. Universal use through double terminal labeling for monitoring relays and overload protection equipment. High contact stability due to models with hard-gold-plated contacts - for use under difficult conditions. Simple and fast troubleshooting thanks to display of wire breakage and short- circuits in the sensor circuit. Wide voltage power packs reduce the number of different versions.
