## Questions & Answers

**Q: The device is labeled 400-415V~ but the item desctiption states 480VAC several times.  Which is correct?**
A: Depending on the voltage you are using will determine the maximum short circuit value. At 400-415 AC is the maximum is 10kA, however at 480 AC the maximum is only 7.5kA.

**Q: The title says 240/480v, but the description says it is for 480v only. is it rated for 20a @ 240v?**
A: i used it as 20Amp 220 volt

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked perfectly and was exactly as described
*by W***S on June 9, 2022*

I used the DIN Rail mounting and added this breaker to a portable machine to feed a VFD Drive. The position indicator was a nice feature because the breaker may be either opened or closed when the machine is in use depending on machine application at the time of use. I am very happy with the product.

### ⭐⭐⭐⭐⭐ You get what you pay for
*by K***M on July 31, 2022*

The cheaper version of this 40amp breaker on Amazon was really unusable and not safe. This breaker is much better. I would probably give it a 4.5 if that was possible. The connectors on this are capable of clamping on to and holding 8ga cable. Which is appropriate for a 40amp circuit.

### ⭐⭐⭐⭐ It's working but...
*by J***N on September 30, 2023*

Why is the breaker labeled 400V and the description says 480V? I'm not sure I trust the seller.
