The MCC "am95" switchboard offers constructive solutions that make it different from most distribution switchboards of the same type.
The "am95" switchboard is designed to meet every customer's need in terms of size, modularity and composition: its versatility not only allows to create any configuration, but also to modify the composition without any limitation, even after its installation.
The standard dimensions of the column are 750x500x2300 cm and a column can have up to 14 "size-1" drawers.
On the same column, the following types of utility services can be placed: fixed, mobile, with inverter, soft-starter, and modular distributors. This solution allows to intervene also when the switchboard is in service, allowing even to convert a fixed unit into a withdrawable one and vice versa.
The modularity also allows - for example in case a 24-hour guaranteed service is required - to have a spare module with the same function, which can replace the one eventually out of service in a few minutes and without turning off the main power supply.
