DC Miniature Circuit Breaker, 2 Pole 1000V 40 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C40

I have 3 Sainty Solar 255 watt panels tied into this before charge controller.

Installed this between my solar panels and the control panel. Works as described.

Works great. Easy to install and operate. They fit well into my solar system.

Good breaker and was easy to install. Feel the money was well spent. Works good.

Used this on a portable power station build to protect my solar panels. Everything working as it should.

Muy como yo lo pedí

The media could not be loaded. I installed it by myself.

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!
