Techna’s Htec DC 10kA Miniature Circuit Breakers (MCBs) allow usage on DC circuits up to 250 Vdc in a single pole and 500 Vdc with two poles in series configuration. The Htec DC 10kA MCB range are polarity sensitive so must be wired correctly.
Our range of Htec DC 10kA MCBs are available in 1 or 2 pole, in a wide range of current ratings from 1A to 63A and are offered in trip curves B and C. We also have add-on Shunt Trip Modules, add-on Auxiliary Contacts and Front Mount Adapters available for our Htec Series MCBs.
The Htec DC miniature circuit breakers are suitable for mounting on DIN-Rail and can also be used inside our Dtec Distribution Boxes and our WINtec IP67 Protection Windows.
