Make sure that the anti-racking-in lock corresponding the one installed the fixed part present the circuit-breaker (moving part). this case, the lifting ropes must hooked shown the figures (the lifting
plates are always supplied with the circuit-breaker).1 Installation room
Install the circuit-breaker dry, dust-free, non-corrosive room, and
in such way that not subject shocks vibrations.2 Installation fixed circu it-b r
Fix the circuit-breaker horizontal surface using the screws (M10 x
