Is that 550 rs belkin surge protector any good? Need to buy aomething to safeguard my air purifier and mi router
Ohh. So what do you suggest getting?? I dont have time and effort to make like you suggested.These cheap power strips usually have a MOV shunt resistor. You can buy these resistors in the market and make one yourself. They will clamp the voltage to whatever the rating of the MOV is (usually 2-3 times the rated voltage). Not sure if any of the manufacturers publish the data (test results) in India.
They will not protect the devices from normal voltage fluctuation (e.g voltage reaching 280-300).
Hard to say. Maybe pick one up which has insurance ( not sure what its worth, I have a few golds but never signed up).Ohh. So what do you suggest getting?? I dont have time and effort to make like you suggested.
Switch on the board is of extremely cheap quality, feels like ticking it on and off multiple times will definitely break it.(amazon reviews will confirm that)Just works means? Its not good?
Better get surge protectors that are installed parallel to the MCB in the distribution box. You need to have a working earth connection for them. They have changeable cartridges which have indicators to show whether they are used up or still working.This is a key point. So is there a way to test their integrity ?
As nobody known when a surge may have compromised them
Im no expert so how ia something like this better than a MCB. I thought mcb also protects against low and high voltage.my Logitech z906 subwoofer just got blown up while being connected to APC BX1100C-IN 1100VA two weeks back. And I have been looking for something foolproof to protect expensive home theater equipment. If you look at Amazon APC feedback, its filled with terrible reviews even for their top of the line BR1000G-IN 1 KVA model. Its the most well known brand in UPS industry but looks like the quality has gone down off lately.
However during my research came accross this:
Something like this for the whole house makes more sense. Still unsure ....
MCB only monitors current. If current is excessive, then it disconnects. Its only purpose is to protect human life. You are asking about protecting appliances. MCB should not and does not.I thought mcb also protects against low and high voltage.
