The transfer switch serves as an equipment to transfer load supply service between two sources.

■ Utility to GeneratorFor application with single utility feeder and a standby generator source. The transfer switch senses loss or abnormality in utility voltage then issues a remote start signal to the standby generator and transfers the load. Load is transferred back under normal utility conditions.

■ Generator to GeneratorFor application in a power system with multiple site generators. Load is transferred to secondary generation in the events of failure or scheduled maintenance.

■ Utility to UtilityFor application with multiple utility feed. Transfer from one source to another is enabled in case of scheduled maintenance of source failure.

■ Multiple Source SystemMultiple Source Systems may include multiple redundant utility feeds and/or multiple standby generators.

Load is transferred to standby source in the event of utility (ies) failure in the case of multiple utility feeds.

Load transfer to secondary generator is accomplished following the failure of both utility and standby generators.

GENERAL CHARACTERISTICS

The ATS is intended for use in low voltage power networks in order to reduce and virtually eliminate outage periods of critical loads. The ATS ratings range from 100A to 3000A to cover the widest range of industrial, commercial and residential needs.

■ Extended product lifetime through minimization of arcing time. ■ On-Load Switching. ■ 3 Stable switch positions (Main Source, Neutral, Emergency Source). ■ Manual Bypass Capabilities. ■ Dual switching strategies: Main ←→ Emergency or Main ←→ Neutral ←→ Emergency.

■ Individual phase enclosure and arc chamber to improve breaking capacity. ■ Enhanced main contact protection & breaking capacity. ■ Easy to maintain. ■ High transfer capabilities for inductive and motor loads.

AUT FEATURES100~3000A

MBH AU’s unique design is optimized to ensure personnel safety, equipment protection and virtually eliminating outages thus combining safety, reliability and fast response. It is widely trusted to maintain service of critical and non-critical processes online at all time to enhance our client’s manufacturing capabilities.

Safety

■ All phases are fully insulated, each in its unique structure. ■ The breaking chambers are fully enclosed to prevent contact with any live parts caused by insulation degradation following an arcing event.

■ Safe conductive performance is ensured by applying adequate contact pressure at all times during operation.

Compact Design

Each phase is fully insulated and is in an independent 1-phase structure. According to the convenience of users, the conduction parts of 3-phase and 4-phase can be combined depending on the capacity and the number of phases.

■ The compact and unique design allows for switching between main source and emergency source through the use of one coil.

■ The uniquely structured arc shute reduces the arc breaking time leading to longer contact lifetime.

■ Stable breaking is ensured by the use of a breaking spring for tripping operations. ■ Low loss and low energy consumption due to the application of instantaneous excitation mode.

■ Both direct source transfer and transfer through neutral stable position are possible.

Reference Standards

The AU Automatic Transfer Switches are designed, manufactured and tested incompliance with the following standards:

■ IEC EN 60947-6-3 ■ IEC EN 60947-6-6

■ Trip

Manual operation is made feasible through the use of a handle connected to the side of the ATS and by making use of a metal pin to control source selection and tripping.

■ CAUTION: ATS Manual operation should be carried out under no load conditions and after careful inspection of live parts.

MANUAL OPERATION

OPERATING CONDITIONS ■ Ambient Conditions

Avoid installation in humid areas, locations with risk of exposure to poisonous gas and high temperature places.

■ OrientationThe ATS is designed to be installed in a specific direction as highlighted in the figure. The ATS feature and performance may be subject to variation if the installation orientation changes. Ideally, the ATS should be installed so as the nameplate can be read properly facing the front and without any twist or bending of any ATS components.

■ Control Circuit ConnectionUse low voltage control/power cable with sufficient length. In case of DC supply, make sure to take into consideration battery and charging characteristics.

■ Main Circuit ConnectionConnect firmly by selecting appropriate wire sizes and solderless terminals. Avoid applying excessive stress to the main circuit terminal.

■ Maintenance & InspectionConduct maintenance and inspection at regular cycles in order to maintain the ATS performance.
