Over and under voltage relays , personally all of us should have these in our DB's:

 

I bought these and are very chuffed with them, imported a few extras if anyone is interested. Yes you can order it yourself, and wait, please do.

I was thinking that SPD's are so expensive so i imported these ones to test, after installing i think they are a very good idea for extra protection:

1. The other day i talked to a client where the municipality had a disconnected neutral and his house was fed with 400V, these relays protect you and will save you Thousands of rands in a case like this.

2. In theory they will help for any surge over voltage.

3. They have over current protection as well.

4. Easy to install, DIN rail.

5. Under voltage can be just as harm full, protects for this also/

6. When council power is restore, it delays the switch on the house and will protect you against the inrush current or possible low voltage or multiple reconnects.

7.Cheap.
