Thermistor engine protection relay, standard, spring connection, 2W, AC / DC 24-240V

Thermistor engine protection relay standard evaluation device 22.5 mm housing suspension terminal 2 changers US = AC / DC 24 V-240 V hand / car / remote RESET with ATEX- approval 2 LEDs (READY / TRIPPED) safe galvanic separation test / RESET- key wire break monitoring short circuit monitoring zero voltage-proof thermist motor protection relay SIRIUS 3RN2 for the protection of engines from overheating even in the explosive range by direct temperature measurement with ATEX- approval. The direct measurement of the engine winding temperature allows the protection of an engine even under unusual conditions such as heavy-duty, braking, frequent switching or insufficient cooling and thus saves a precautionary oversize of the engine. The equipment can be used for the protection of engines in gas or dust-related areas. By using PTC sensors, a parametrization of the devices is not necessary. LEDs allow quick error diagnosis. The devices are climate-resistant, contact-safe and can be used worldwide thanks to wide-voltage range and international applications. Available as mono or bistabile evaluation equipment, with and without ATEX approval, with one or two contact groups and with car, hand and / or remote RESET. The devices are available in screw or spring drawing technology (Push-In). There are versions in construction width 17.5 mm or 22.5 mm, for hat rail TH35 or for screw fitting with adapter (accessories) and with hard-gilded contacts. Uniform accessories for all device variants, such as removable clamps, plug-in pockets and encoding stifles, simplify the selection and storage. The 3RN2 thermistor engine protection relays release the proven 3RN1 series. SIRIUS Relais - a program for all cases.
