Automatic Transfer Switch (ATS)Utilization scopeAuto Transfer Switch is a self-acting equipment containing the transferswitching devices and other necessary devices for monitoring supplycircuits and for transferring one or more load circuits from one supplyto another.The operating sequence of ATS consists of an automatic transfer ofa load from the normal supply to an alternate supply in the event of amonitored supply deviation and automatically returning the load to thenormal supply when quality of mains supply is restored. The transfer iswith a predetermined time delay and includes an interim off position.In case of both the normal and the alternate supplies being present,the ATS shall assume the normal supply position, which is termed as‘preferred supply’.The various utilization categories show the most popular applicationsof Auto Transfer Switch, as per IEC-60947-6-1.Nature of currentAlternating CurrentDirect CurrentUtilization CategoryOperations A Operations BAC-31AAC-31BAC-32AAC-32BAC-33AAC-33BAC-35AAC-35BAC-36AAC-36BDC-31ADC-31BDC-33ADC-33BDC-36ADC-36BTypical applicationsNon-inductive or slightly inductive loads.

While the trip coil operates using 220V AC available from eitherof the electrical sources, the protection unit requires 12 DC battery input for its functioning. The same needs to be made available from an uninterrupted source such asexternal battery being used for self start generator set.Dimensional details (in mm) - Open ExecutionFrameSizeCurrentRating(A)No. ofPolesOver AllSwitch Mounting Connection TerminalsDimensionsTerminalBolt SizeA B C J K L P R S T V W Y Y1Weight1 100 3P 257 241 122 201 139 f9 38 15 30 4 30 32 40 90 M8x30MM 8.3Kg100 4P 295 241 122 201 177 f9 38 15 30 4 30 32 40 90 M8x30MM 9.3Kg1 160 3P 257 241 122 201 139 f9 38 15 30 4 30 32 40 90 M8x30MM 8.7Kg160 4P 295 241 122 201 177 f9 38 15 30 4 30 32 40 90 M8x30MM 9.7Kg2 200 3P 290 253 122 213 172 f9 48 30 30 5 35 38 40 90 M8x30MM 10.5Kg200 4P 338 253 122 213 221 f9 48 30 30 5 35 38 40 90 M8x30MM 11.5Kg2 315 3P 290 253 122 213 172 f9 48 30 30 5 35 38 40 90 M8x30MM 11.0Kg315 4P 338 253 122 213 221 f9 48 30 30 5 35 38 40 90 M8x30MM 12.0Kg3 400 3P 340 337 144 290 208 f10 60 40 40 5 42 42 38 110 M10x40MM 19.5Kg400 4P 400 337 144 290 270 f10 60 40 40 5 42 42 38 110 M10x40MM 21.0Kg3 630 3P 340 337 144 290 208 f10 60 44 40 7 42 42 38 110 M10x40MM 21.0Kg630 4P 400 337 144 290 270 f10 60 44 40 7 42 42 38 110 M10x40MM 22.5Kg90
