Great DC Breaker
I used this 32A 2-pole DC breaker as a disconnect between my solar panels and charge controller, and it’s been a solid addition to my system. The DIN rail mounting made installation quick, and the terminals held my wiring securely with no issues. The switch has a firm, positive feel when turning it on and off, and having both overload protection and an easy way to isolate the PV array adds peace of mind when working on the system. It feels well-built and is compact enough to fit neatly inside my electrical enclosure. If you’re building or upgrading a solar setup and need a reliable DC disconnect, this breaker is a great value and performs exactly as expected. Highly recommended.

Great Protection
I installed 3 of these almost a year ago. I have had no issues with PV voltages from 3 solar arrays, all putting out up to 500 Vdc at times. I recently rewired a PV array of 12 panels. Made the mistake of inverting the polarity. When I turned on the breaker, it smoked, bigtime! then all was silent. No fire, no melting of the breaker. I measured the voltage at the input and realized the polarity was reversed. My bad! I disabled the voltage at the panels, rewired correctly, and connected to a new breaker. All worked well. My biggest point with this review is, even though the breaker fried, it kept the reverse voltage of over 400 Vdc from getting to the solar inverter and causing hundreds to thousands of dollars in damage. The breaker not only will trip if the amperage is exceeded, but also protects from reversed Vdc. Very thankful!

Poorly cut rail mount
Switch is good but the rail mount edges are very poorly cut, I used a Duckbill Plier and a file to straighten and flatten the edges so it will slide in smoothly

Bent rail
The rail mount is bent so the circuit breaker will not slide onto it.
