Questions about this product

Can I use a standard AC circuit breaker instead of this DC breaker for my solar panels?
No, you should not use an AC breaker for DC solar systems. This TOMZN breaker is specifically designed with a dedicated DC arc extinguishing system to quench arcs safely. Standard AC breakers cannot safely interrupt the continuous arcs that high-voltage DC current generates under fault conditions.
What current ratings are available for this breaker, and what wire sizes does it accept?
We offer this breaker in current ratings from 3A up to 63A to match your system. The terminal clamps accept flexible or stranded wires ranging from 1 mm² to 25 mm². This range makes it easy to protect everything from small branch circuits to your main battery bank.
How do I mount this TOMZN DC breaker in my solar setup?
This breaker mounts directly onto a standard 35mm DIN rail, supporting TH35-7.5 and TH35-15 profiles. You can easily snap it into your existing combiner box or distribution board. Its compact 2-pole design saves space while completely isolating both the positive and negative DC lines.
