Can I use this circuit breaker in a standard AC household panel?

No, this breaker is specifically rated for high-voltage DC systems up to 1000V. Standard AC breakers cannot safely extinguish DC arcs, which can cause fires. Use this model only for solar arrays, battery banks, or other DC applications.

Does it matter how I connect the wires to the positive and negative terminals?

Yes, polarity matters. The breaker housing has clear positive (+) and negative (-) markings that you must follow during installation. Incorrect wiring can prevent the breaker from safely quenching arcs during a fault. Mount it on a standard 35mm DIN rail inside your combiner box or inverter enclosure.

How do I choose the right amperage rating for my solar setup?

We offer models ranging from 6A to 63A to match your specific panel configuration. Check your solar panel's short-circuit current rating and multiply it by 1.56 to find the target size. Just ensure your system voltage doesn't exceed the 1000V DC limit.
