Not Worth the Investment for Industrial and Scientific Use

This circuit protection product was a complete waste of money when I tried it out. While it claims to provide ultimate circuit protection, it did not hold up to the test. The product is not reliable and its quality is questionable.

Pros
  • None
Cons
  • Unreliable, questionable quality.

Easier repair in Breakers, Load Centers and Fuses

I failed the Add test because my Siemens panel had too many circuits to not have a single trip point. I was looking for some essential replacement wiring to add a 100 ohm switch. Then I examined the box and found that this switch could be added. It took 5 minutes.

Pros
  • Breakers, Load Centers and Fuses
Cons
  • Hide

I ordered a new Siemens main switchboard and this one.

I ordered a new Siemens main switch panel and this 100A main switch was switched off on arrival. So I ordered this "used" switch and it works great. Turns on/off as needed. I haven't tried pulling >100A through it, so I haven't tested it to see if it works properly.

Pros
  • Tools and household goods
Cons
  • Large and bulky
