Techna’s Htec 10kA Miniature Circuit Breakers (MCBs) will automatically switch off the power supply if the electrical circuit is overloaded and will also provide short circuit protection. The Htec 10kA MCB range has been enthusiastically adopted by a diverse range of customers that seek a cost effective 10kA performance and protection.
Our range of Htec 10kA MCBs are available in 1 to 4 pole, in a wide range of current ratings from 0.5A to 63A and are offered in trip curves B, C and D. We also have add-on Shunt Trip Modules, add-on Auxiliary Contacts and Front Mount Adapters available for our Htec Series MCBs.
The Htec 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.
