1 MNS iS Design & Components
1.1 Switchboard Construction
MNS iS as part of the ABB Low Voltage
Switchgear solution uses the well proven ABB
MNS standard design aspects. MNS aspects
described in this section are fully applicable to
MNS iS.
MNS system is a verified design in accordance
with IEC61439-1/-2.
The consistent application of the modular
principle both in electrical and mechanical design
as well as the use of standardized components
allows its flexible and compact design.
Depending on operating and environmental
conditions different design levels are offered.
Notable system advantages with regard to
design aspects:
 Compact, space-saving design
 Easy project and detail engineering
through standardised components
 Verified design acc. IEC 61439-1/-2
 Earthquake-, vibration- and shock-proof
designs are available
 Easy retrofitting without the need for
switchgear de-energizing
 Maintenance-free busbar construction
 High operational reliability and availability
 Optimum personal protection
1.1.1 Functional separation
The switchboard is divided into vertical and
horizontal compartments thus separating different
functional areas.
As even power cabling and control wiring are
strictly separated within MNS iS, the switch-
board is structured as follows:
Figure 1 Functional areas: Incomer and MCC
1. Equipment compartment
All equipment, including the standard motor
starter modules MStart or feeder modules
MFeed in withdrawable design, is situated
therein. The compartment can be divided in
horizontal and vertical sub compartments.
2. Control cable compartment
Contains the integrated control devices
MControl, control cables and terminals.
3. Power cable compartment
Contains power cables and connection units.
4. Busbar compartment
Contains the MNS main busbar system and
distribution bars. The distribution bars are
embedded in the Multifunction Separation Wall
(MFW) which is located between the Equipment
compartment and the Busbar compartment
