Jtec489 DC 10kA MCBs

Techna’s Jtec489 DC 10kA Miniature Circuit Breakers (MCBs) allow usage on DC circuits up to 125 Vdc in a single pole and 250 Vdc with two poles in series configuration. The Jtec489 DC 10kA MCB range are polarity sensitive so must be wired correctly. Our Jtec489 DC range offers maximum performance at excellent prices.

Our range of Jtec489 DC 10kA Branch Circuit Breakers are available in 1 or 2 pole, in a wide range of current ratings from 0.2A to 63A, are offered in trip curves B, C and D and suitable for mounting on DIN-Rail. A range of accessories are also available for the Jtec489 DC Series MCBs.
