For emergency power in buildings, an Auto Transfer Switch (ATS) is essential. The ATS can automatically transfer load from main power to emergency power without operator intervention. When the main power fails or voltage drop below 80% of normal voltage, the ATS will start the emergency generator, after a preset time of 0 to 10 seconds (adjustable). At rated speed, the ATS will transfer load to emergency power with available size ranging from 32A to 4000A. There is a switch suitable for every project’s need.
- Mechanically held contactor & Breaker
- Optionally 4 or 3 pole
- Rating range from 32 to 4000A
Types of ATS:
ATS Motorized Type:
Automatic transfer switch consists of Motorized breaker (MCCB/ ACB) electrically and mechanically interlocked as per the regulations and standards of local Authorities SEWA/ DEWA/ ADDC/ FEWA.
ATS Contactor Type:
Automatic transfer switch consists of 4 pole/ 3 pole contactors mechanically interlocked to transfer the load automactically.
ATS Changeover Type:
Automatic transfer switch consists of Changeover (Automatic) 4 pole/ 3 pole motorized to transfer the load automactically along with the option of manual bypass.
