ABB - Automatic Transfer Switches

ATS021 & ATS022

ABB presents the new generation of Automatic Transfer Switches, the result of worldwide experience in low voltage applications. The new generation of the ATS family – ATS021 and ATS022, offers the most advanced and comprehensive power continuity solution. Reliability, safety and intelligence are the major features of the new ATS family, which complies with international standards, is simple to configure and adaptable to all application scenarios. Moreover, its perfect integration with all ABB circuitbreakers and switch-disconnectors ensures a fully coordinated system.

Multi-function logic to meet all requirements • Standard switching logic allows monitoring of the normal and emergency line, sending commands to the generator and controlling that the circuit-breakers have been switched

• Management of both the two non–priority lines (ATS021, ATS022)
• Management of a third bus-tie circuit-breaker (ATS022)
• Management of non-priority load disconnection.

Ordering Codes:

• 1SDA065523R1 ATS021 Automatic transfer switch

• 1SDA065524R1 ATS022 Automatic transfer switch

No auxiliary power supply required The new ATS family is designed to work without an auxiliary power supply. An auxiliary power supply is only required when Modbus RS485 communication is used or in networks with 16 2/3 Hz rated frequency.

Compliance with IEC and EN 60947 Standards Compliance with the IEC and EN 60947 Standards allows the new ATS family to provide the quality and safety needed for all requirements.

Compatibility with ABB circuit-breakers and switchdisconnectors The ATS family can be used with ABB SACE Tmax (XT1... XT4, T3...T7) and Emax (X1, E1...E6) series of circuit-breakers and switch-disconnectors, fitting into a complete and coordinated system.

Advanced communication interface ATS022 is equipped with a communication unit which allows integration with the supervision systems via Modbus RS485. Furthermore, ATS022 is fitted with a graphic display which makes parameter configuration and display extremely simple.

The ATS family is particularly suited to use in all emergency power supply systems where a solution which is simple to use, reliable and rapid to install is required. Below are some of the main applications of ATS:

• Power supply for UPS units
• Operating theatres and primary hospital services
• Emergency power supplies for civil building, hotels and airports
• Data banks and telecommunication systems
• Power supply of industrial line for continuous processes.
