I needed a circuit breaker for my new water heater and this was perfect for what I needed. Delivery was very quick and the price couldn't be beat. I usually buy products from Square D and they are great, but I saw this and compared the prices. I trust Siemens and Square D, that's why I bought this switch. It's only been a few days, but it's an essential part of a tankless water heater upgrade. It fitted perfectly into my HOM2040M200PCVP Homeline 200A 20 Bay 40 Circuit Main Breaker load center and I have to say the build quality of this breaker seems to be a bit better than others I already have. Will definitely be returning to this brand when ordering the rest of the breakers I need later.
