Review: Great DC Circuit breakers that add valuable safety - DC circuit breaker for 12-110 volts DC. I use these on my solar storage batteries as a safety device. It’s easy to forget how much amperage these batteries have and how fast things can go wrong if a short circuit occurs. You can quickly burn your house down with unprotected high amperage wiring that turns red hot burning anything in its path. Do NOT chance it going without protection even with only 12 volts. It’s the high amperage you need to worry about.
Review: Perfecto para mis baterías, funcionando muy bien
