Product description

The Siemens 3RN2013-1GW30 is a thermistor motor protection relay, part of the standard evaluation unit series, featuring a 22.5 mm enclosure and screw terminals. It includes 2 changeover contacts with hard gold-plating for enhanced reliability.

This relay operates on a supply voltage (Us) of 24 V-240 V AC/DC and offers manual, auto, and remote reset options. It possesses ATEX approval, making it suitable for hazardous environments, and features 2 LEDs for status indication (ready/tripped). The relay also provides safe electrical isolation, a test/RESET button, wire-break monitoring, and short-circuit monitoring, with non-volatile memory.

This advanced motor protection relay is ideal for protecting motors against overheating, especially in critical applications where contact reliability is paramount, such as in industries with harsh environmental conditions or demanding operational cycles.
