Description

• Overload protection – trip class 10A

• Phase loss sensitivity

• Disconnect function

• Temperature compensation from -25 … +50 °C

• Adjustable current setting for overload protection

• Suitable for three- and single-phase application

• Trip-free mechanism

• Clear switch position indication ON/OFF

Manual motor starters (also known

as motor protection circuit

breakers or manual motor

protectors) are electromechanical

protection devices for the main

circuit mainly used to switch

motors manually ON/OFF and

protect them fuseless against

short‑circuits, overloads and phase

failures. Fuseless protection with a

manual motor starter saves costs,

space and ensures a quick reaction

under short-circuit condition, by

switching off the motor within

milliseconds. Fuseless starter

combinations are setup together 

with contactors.

Plant description

Pipelines are the most efficient way to distribute gas and

cover big distances especially in location with critical

environmental conditions like deserts, glaciers, high

mountains. To keep pressure and temperature of gas at the

right level, Gas Compressor Stations are present and placed

at 10 to 150 Km intervals along the pipeline. The low voltage

MCC is one of the most important and critical component of

those compressor stations

The two WAGP Gas Compressor Stations in Utorogu and

Oben are based on the latest ABB MNS iS technology

installed into prefabricated E-houses.

The ABB MNS iS is the right solution to comply with the high

level of integration and compactness requested for the WAGP

Utorogu and Oben Gas Compressor Stations.

The ABB MNS iS Power and Motor Control Centers for the

WAGP project are fully integrated with the station DCS via

serial link (Profibus DP protocol) and are built in compliance

with Shell DEP standards.

Scope of supply

ABB S.p.A. (Italy), in cooperation with Lee Engineering &

Construction Co (Nigeria) and Franzisella S.p.A. (Italy), is

MNS iS Design & Components

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
