Circuit diagram of the DIGmat S100 and the 3WL non-automatic air circuit

breaker

Application examples

The connection to the circuit breakers is not dependent on direc-

tion and polarity; the circuit diagrams can be adapted accord-

ingly.

If the parallel or series connections are made directly at the

connecting bars, for thermal reasons the continuous load on the

circuit breakers must only be 80 % of the permissible operational

current. If the parallel or series connection is made at a distance

of 1 m from the connecting bars, the circuit breaker can be used

at full operational current load.
