The product you see in the picture is the powertrain "ZNCXB01ZM" model, which is produced by Xiaomi with unique features. First of all you should know that the powertrain is not an electronic protector. The multiplexer merely divides the output voltage into several ports, but the electronic shield is designed to protect electronics such as TVs, computers, etc. against power fluctuations and noise on your power line. The point to be aware of is that you should not mistakenly choose a multi-path instead of an electronic shield. When shopping, look for words such as shielding, mute switch or fuse.
