Techna’s Jtec DC 4.5kA Miniature Circuit Breakers (MCBs) allow usage on DC circuits up to 220 Vdc in a single pole and 440 Vdc with two poles in series configuration. The Jtec DC 4.5kA MCB range are polarity sensitive so must be wired correctly.
Our range of Jtec DC 4.5kA MCBs are available in 1 or 2 pole, in a wide range of current ratings from 0.5A to 63A and are offered in trip curves B and C. A range of accessories are also available for our Jtec DC Series MCBs.
The Jtec 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.
