Device circuit breaker boards for eight thermomagnetic (CB TM1...) or electronic (CB E1... NO) circuit breakers with group remote signaling, central supply, connection for relay contacts, and potential distribution for up to four loads per channel. 

## Your advantages 

Reduced installation time thanks to multi-channel device Circuit Breakers Board (4/8/12 channels) 

Space savings of up to 35% thanks to compact design 

Fuse protection of up to 12 A per channel provides best possible protection for connected loads 

Up to 4 loads can be protected simultaneously with the additional terminal points 

Integrated group remote signaling ensures that you are always kept informed 

High current carrying capacity of the board supports supply of up to 60 A 

w Maximum overcurrent protection over long cable paths thanks to device circuit breakers with SFB characteristic curve or electronic device circuit breakers
