Surge protector placement

I have just noticed in my new Square D panel that the "breaker type" surge protector has been placed about half way down i.e. not in the top two breaker places.

Does this matter? I understand that for optimal performance a surge protector should be wired as close to the bus bar as possible. Is there anything wrong with what my electrician has done?

Thanks.

All the breaker positions fasten to the bus bar. A surge would be "instanteous" along the entire bus, and your protector should drain it off equally well regardless of its location in the panel.

Thank you hj.
