    Siemens PFP3 Filler Plate
    I recommend this product
    Rated 5 out of 5 stars

    Easy to order and Quick Shipping

    I needed some filler plates for an older breaker panel. Not available at any retail places I could find, thankfully Superbreakers had them. A couple minor issues: they didn't include the size specifications (L x W x D) online, which would have helped confirm they were the right fit; and they included an unrelated picture (along with the right one).

    But the online order processing was easy-to-use and had all the info needed (especially the shipping options/costs, and the return policy). They also stuck to their word about getting it out in 24 hours. It arrived via UPS Ground in a respectful 5 days. They of course fit the panel and all is well.

    Overall, very pleased with the company.

    The part was correct,, but

    The part was correct,, but I was shocked when the cheapest (ground) shipping was almost as much as the part that only weighed 8 ounces. The part was $14.03 and the shipping was almost $13.00.

    Happy with my Purchase

    This is the 4th time I have used SuperBreakers and have been happy with my purchase every time. I have an old style style system in my house and the company I was using told me the old style breakers were impossible to find and charged me $80 each. Next time I needed one I found SuperBreakers had them for $15 each. I am no longer using that electrical company.
