The 3VL molded case circuit breaker can be connected using cables, flexible copper bars or
busbars.
Thermal and electrodynamic stresses affect these conductors in the event of a short-circuit.
To avoid dangerous effects, it is necessary to asses them correctly and to take appropriate
measures to suppress them.
The diagrams and tables below show the recommended maximum clearance between the
molded case circuit breaker and the first point.
