Can I use this circuit breaker for standard AC home electrical panels?

No, this breaker is designed specifically for high-voltage DC solar systems up to 1000V. It uses a magnetic blow-out and de-ion chamber to safely extinguish dangerous DC electrical arcs. Standard AC breakers cannot handle these arcs and will fail if you use them here.

What current and pole options can I choose from to match my solar array?

We offer this breaker in current ratings ranging from 6A all the way up to 125A. You can select single, double, triple, or four-pole configurations to match your system design. This range makes it easy to find the exact match for your specific solar array.

How does this breaker mount, and what size wires can I connect to it?

This miniature circuit breaker mounts directly onto a standard DIN rail to save space. Each pole has a width of 18 millimeters, allowing for clean layouts in your combiner box. The connection terminals can accommodate heavy-duty PV wiring up to 25 square millimeters.
