Does the job well
Ordered as circuit breaker/isolator to sit between 2 160W solar panels and Epever solar controller on my narrowboat solar setup. Good design with track supplied so easy to install. Easy access terminal slots so no issues with cables and connectors supplied in separate packet. Ensure cable firmly gripped to 'spade end' connector so doesn't pop out. Easy to operate manually, have not had a 'forced' disconnect yet. Recommended.

Läuft bei mir jetzt ca. 2 Wochen, keine Probleme; Das einzige was ist, der 40A Sicherungsautomat wird bei ca. 30A seitlich LI+RE ordentlich warm, also sollte man seitlich einen abstand lassen?
