TOMZN Voltage Protection Relays TOSVA-16 & TOSVA-16LM — Review & Test

Опубликовано 7 февраля 2026, 18:23

In this video, we take a detailed look at two TOMZN voltage protection relays — the TOSVA-16 in a socket format and the TOSVA-16LM in the form of an extension cord. We will see how they look in real life, how they differ from each other, and what tasks they are suitable for. We will look inside the devices, evaluate the build quality and component base. I will show the setup process — we will go through the main voltage and current protection parameters. In the final part, we will conduct practical tests: we will check shutdown at low voltage and at exceeding the set current value to understand whether these relays are really capable of protecting connected equipment.
