Jtec489 10kA MCBs

Techna’s Jtec489 10kA Miniature Circuit Breakers (MCBs) are UL Listed as UL 489, File E255530, as a Branch Circuit Breaker and is therefore able to be used to protect a branch circuit without a backup device. Many applications and other UL Standards insist upon the use of a Branch Circuit Breaker, as opposed to a Supplementary Protector, so if you use the Jtec489, you will be covered. Our Jtec489 range also offers maximum performance at excellent prices.

Our range of Jtec489 10kA Branch Circuit Breakers are available in 1 to 4 pole, in a wide range of current ratings from 0.2A to 63A, are offered in trip curves Z (very quick), B (quick), C (medium), K (motor) and D (long delay) and suitable for mounting on DIN-Rail. A range of accessories are also available for the Jtec489.
