1.3 Fixed Module Design
For
specific applications MStart is offered in
fixed design. The module size is 85E (full
height of the switchboard).
Fixed modules are utilised for motor starting
solutions where a rating in excess of 250kW is
required for DOL starting and 160kW for Star
Delta.
The motor starter components such as the
switching device, contactor and shunt modules
are mounted in the main compartment.
The MControl and field I/O connections are
located either in the upper compartment or
lower compartment, dependant upon the cable
entry requirements. For example, when cable
entry is from below the MControl is located in
the upper compartment and vice versa.
