Jtec 10kA High Current MCBs

Techna’s Jtec 10kA High Current Miniature Circuit Breakers (MCBs) have much higher current ratings compared to our standard Jtec MCBs. Just like our standard range of Jtec miniature circuit breakers, these high current versions also provide cost effective 10kA performance and protection, specifically in demanding applications that require high amperage. Due to the higher current ratings, these MCBs are 27mm wide (1.5 modules) per pole.

Our range of Jtec 10kA High Current MCBs are available in 1 to 4 pole, in current ratings 80A, 100A or 125A, are offered in trip curves B, C and D and suitable for mounting on DIN-Rail. Factory fitted accessories are also available for our Jtec high current MCBs.

For less demanding applications, we recommend our standard range of Jtec 10kA Miniature Circuit Breakers (MCBs), available in 1 to 4 pole, in a wide range of current ratings from 0.2A to 63A and in trip curves B, C, D, K and Z.
