Voltage relay RN-122 NTRN12200

Protect your devices with the voltage relay RN-122

The RN-122 voltage relay is a reliable device that will protect your household appliances with a power of up to 3.6 kW against harmful voltage fluctuations in the electrical network. It is an ideal solution for refrigerators, air conditioners, washing machines, audio-video equipment, gas boilers and many more. It protects against the effects of interruptions in the neutral conductor, ensuring continuous operation and extending the life of the connected equipment.

Functionality and ease of use

RN-122 not only protects, but also informs. It is equipped with LED diodes indicating the voltage value in the network and its presence in the socket. Additionally, it records and stores in memory the maximum and minimum voltage values, allowing you to monitor the condition of the electrical network. Automatic re-engagement (ARR) after the restoration of correct network parameters ensures ease of use – you do not have to manually start devices after short-term voltage drops. Built-in overheating protection guarantees the safety of the device and the protected equipment. If the internal temperature exceeds 85°C, the relay will switch off, signaling a problem and preventing damage.

Installation and application – for professionals and users

The RN-122 relay is easy to install and operate. It provides effective protection against voltage surges for a wide range of household appliances. Installers will appreciate its compact dimensions (122x61x76 mm) and simple connection. End users gain confidence that their equipment is safe and protected against failures caused by an unstable power grid. Thanks to the adjustable voltage range (Umin 160-210V, Umax 230-290V) and the automatic re-engagement time (5-900 seconds), the relay's operation can be adapted to specific needs and installation conditions. The rated current of 10A allows you to protect devices with higher power consumption within the limit of 3.6kW.
