(Showing 8 of 8)

Techna’s Jtec 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 Jtec 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 Jtec 10kA MCBs are available in 1 to 4 pole, in a wide range of current ratings from 0.2A to 63A and are offered in trip curves B, C, D, K and Z. A range of accessories are also available for our Jtec Series MCBs.

The Jtec 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.

For more demanding applications, we also offer a range of Jtec 10kA High Current Miniature Circuit Breakers (MCBs), available in 1 to 4 pole, in current ratings from 80A to 125A and in trip curves B, C and D.
