Power supply
Masterpact devices can be supplied either from the top or from the bottom without
reduction in performance, in order to facilitate connection when installed in a
switchboard.

Mounting the circuit-breaker
It is important to distribute the weight of the device uniformily over a rigid mounting
surface such as rails or a base plate.
This mounting plane should be perfectly flat (tolerance on support flatness: 2 mm).
This eliminates any risk of deformation which could interfere with correct operation
of the circuit breaker.
Masterpact devices can also be mounted on a vertical plane using the special
brackets.
