Be advised
It fits my applicationA three phase Siemens PL Series panelIts a tight fit to get it to click in had to beat it on with a hammer.Be advised you will probably not pass any sort of inspection or codes due to the fact of this product not being UL Listed.It’s just a no name breaker. I used this instead of the brand name as an alternative due to the fact it’s about $25-$30 less per breaker and easily available.The brand name breaker i needed was hard to find and several weeks out depending on the supplier
