Measurement variables Selectable temperature, current and voltage measurement for various protection needs for both motor and the switchgear itself. No traditional transformers are utilized for any measurements. System accessibility with ‘off the shelf’ web browser based devices With an inbuilt web server functionality, the user can select any web browser based device to interrogate the system. Information distribution as required Industry standard communication interfaces, such as Profibus DP, ProfiNet, Modbus RTU, Modbus TCP and OPC are available, enabling site wide distribution of...

MNS iS System Overview Function module concept MNS iS motor control center solution delivers all the functions for control, protection and monitoring of the motors and motor starters using software and hardware modules for the specific tasks. Right information is provided to the right people at the right time. Hardware modules are designed to fulfill desired tasks (power module containing electrical parts e.g. to isolate power, control module containing software applications etc. to control a motor). System functions are provided as functional modules to be downloaded to the control module....

Components overview The power module MStart/MFeed comprises: - the electrical isolator - the short circuit protection device (fuses or circuit breaker) - contactor and any electrical control equipment and status indication - the sensor module (measuring the electrical values, which are then available to the process via the MControl module) The interface module MLink serves as the gateway to higher level systems which communicate via the internal bus to all MControl modules. A local human system interface MView is available to monitor the MNS iS status and display information on each...

MNS iS Design Aspects Switchboard construction MNS iS as part of the ABB low voltage switch­ ear solution g uses the well proven ABB MNS standard design aspects. MNS aspects de­ cribed in this section are fully applicable to s MNS iS. MNS system is a verified low voltage switchgear design in accordance with IEC 61439 series and IEC 61641. 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...

MNS iS Design Aspects Switchboard arrangements MNS iS cubicles can be arranged as follows: - in standard execution (back-to-wall), - back-to-back or - duplex. For switchgear dimensions, see Technical Data section. Standard (Back-to-wall) 14 System Guide | MNS iS Motor Control Center Duplex (common busbar compartment)

Frame construction The basic elements of the MNS iS frame construction are “C” shaped steel profiles with a 25 mm hole pitch according to DIN 43660. This 25 mm equals the dimension of 1E used in MNS to define the area usage within the switchgear. MNS iS switchboard enclosure is made of sheet steel protected by galvanic coating and powder coating for maximum durability. Each cubicle is precision constructed by bolting horizontal and vertical profiles together, to form a rigid modular structure. The assembly is maintenance free as a result of the construction method utilizing a combination of...
