The device is designed for single-phase networks, is installed on a DIN rail, and is equipped with built-in thermal protection, which increases operational safety. This model from the manufacturer Promavtomatika Vinnytsia is made in Ukraine and comes with a 5-year warranty, confirming its high quality and durability.

Specifications

The RNm 140 t 40A voltage relay is suitable for protecting household and professional electrical equipment: boilers, pumps, compressors, lighting systems, and other equipment sensitive to mains voltage fluctuations. Thanks to the upper trip limit range of 230-270V and the lower limit of 130-210V, the device effectively responds to both excessive and insufficient voltage. The Δ5 V hysteresis ensures stable return to operating mode without "relaxation" during small fluctuations. The rated current of 40A and the ability to withstand peak loads up to 63A make this regulator suitable for most standard loads in residential and commercial networks.

DIN rail mounting allows for quick installation of the relay in the switchboard alongside other modular devices. Built-in thermal protection adds a level of safety during intensive operation or elevated ambient temperatures. The IP20 protection rating implies installation in enclosed cabinets and distribution boards.

By purchasing the RNm 140 t 40A from Promavtomatika Vinnytsia, you get a reliable device with a 5-year warranty, made in Ukraine, with clear electrical characteristics and convenient DIN rail mounting. The relay provides automatic reclosing in the range of 5-99 seconds, which allows optimizing power restoration after temporary interruptions without the need for manual intervention.
