Product overview
What to Know About Solar DC Breaker & Protection Set
DC breakers serve a similar role to the breakers in your home's electrical panel, but rated for the higher voltages typical in solar PV systems. This protection set is meant to let you safely isolate a string or the whole array for maintenance, and to trip automatically if current exceeds safe limits.
Since the exact manufacturer, pole count, and breaking capacity aren't specified in this listing, confirm these details carefully, and make sure whatever's included matches your PV string's actual current and your inverter's maximum voltage rating before installation.
