Review on Two-module voltage relay Welrok D2-63, 63A with thermal protection (RBUZ) by Adam Kotula ᠌

Revainrating 5 out of 5

The best purchase in my life, I will definitely buy it again.

I bought 100 sq. M. for an apartment, in a house built in 2022, there are enough electrical appliances in the apartment. The connection procedure is as follows: "1. On the site, a single-pole introductory machine for 50A - 2. RCD 63A, with a leakage current of 30mA - 3. Load relay 63A - 4. Load (automatic machines + zero bus)". The cross section of the cable at the input and before the distribution of the load is copper 6 sq. mm. It is desirable that the introductory machine was not equal, one step lower than the nominal value than the RCD and voltage relay. In the settings, I chose a professional model of the shutdown time when the voltage goes beyond the limits.
