    When my SPA stopped working I was suddenly faced with the fear that something major had gone wrong with my SPA. Deciding to do some basic troubleshooting with a multimeter I noticed that one leg of the circuit was only producing 45 VAC and the other was 110 VAC. Tracing it back to the main panel I got the same readings. Obviously, the circuit breaker was bad and needed to be replaced. I was surprised to find an exact replacement at . Got home and swapped out the breaker. Problem solved! For less than the price of a good steak dinner, I was soaking in the satisfaction of being self-sufficient. Thanks, !

    I have Zinsco circuit breakers at my house. What I have read is that they are not very good (though they are quite pricy). I have two AC units (one upstairs and one downstairs).
    The downstairs AC kept tripping the breaker and I thought maybe the unit was going bad. But then I thought, well if the circuit was bad it would probably not run at all. What was happening is that the AC would run for several minutes and then trip. So than I decided that before I call out an AC guy to check the unit I would try just swapping out the breaker to see it that worked. It did. So I guess the breaker was overheating which was tripping the breaker. It has been working now for a few weeks so I declare it a good fix and I probably saved a couple of hundred dollars.
    This is an after market product but for all I know it will work better than the original.

    We had a twin 20 that had one weak side. I swapped it out in less than 15 minutes as that was the time limit on out back-up battery. Also, Lowe’s was 20-30 dollars cheaper than everyone else. Thanks again, Lowe’s!
    I’m able to run the air conditioner in the office again.

    Worked perfect! UL approved Zinsco/Sylvania GTE replacement – saved me $3k woodchuck estimates from 2 electricians. Electrician I latered hired recognized product as safe.

    the breakers has stood the test of time, yes they suck to pull and they rant made anymore, but if you have a can and this type of breaker there usually a good product

    I own an older home and parts for older systems can be hard to find. Lost power on a very hot day needed a breaker now! They had it in stock! Cool!

    It’s a circuit breaker so it’s kinda hard to get all excited about it but it went right in and didn’t explode. That’s good, right?

    This breaker is replacing a bad breaker. It fits perfectly in my Sylvania/Gte box. It replaces a Zinsco breaker.
