ATyS r from 125 to 3200 A

ATyS r is three-phase remotely operated motorized transfer switches, available in 3 or 4 poles, with positive break indication.

They enable the on load transfer of two three-phase power supplies via remote volt-free contacts, from either an external automatic controller, using pulse logic, or a switch.

They are intended for use in low voltage power systems where interruption of the load supply is acceptable during transfer.

Advantages

Watchdog relay to check product availability

ATyS r is equipped with a Watchdog relay which constantly monitors your product, thereby securing the installation. This relay informs in real time the user of the product's availability.

Extended power supply range

It offers greater availability thanks to their extensive power supply range of 208 to 277 VAC ± 20%.

Integrated auxiliary contacts

As part of the product monitoring function, ATyS r enable the transmission of information relating to its position. Thanks to the standard integration of an auxiliary contact for each position.

ATyS S from 40 to 125 A

ATyS S products are 4 pole remotely operated transfer switches with positive break indication. They enable the on load transfer of two three-phase supplies via remote volt-free contacts, from either an external automatic controller, using pulse logic, or a switch. They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer

Advantages

Extensive power supply range

The ATyS S is available in four supply versions, each with a broad range (+/-30%). The four versions are:

  • 12 VDC power supply.
  • 24/48 VDC power supply.
  • 230 VAC single power supply.
  • 230 VAC single power supply.
Safety and reliability

ATyS S products use stable position technology, ensuring constant pressure on the contacts and preventing premature faults

Easy integration

ATyS S products can be easily installed inside enclosures. Their design, and in particular their compact size, enables integration within most 200 mm deep enclosures

ATyS d H from 4000 to 6300 A

The ATyS d H is a three-phase transfer switch, 3 and 4 poles, designed for low voltage high power applications that require high-performance and fast reliable switching. The open transition transfer is performed on-load in line with IEC 60947-6-1 and GB 14048-11 standards (Class PC) with minimal power supply interruption to the load during transfer. The ATyS d H is remote transfer switching equipment (RTSE) with an integrated dual power supply (DPS) that accepts remote orders through volt-free contacts.

Advantages

Ready for installation in the enclosure of your choice

It is composed of two switches that are mounted one above the other with easily accessible power connections located at the rear. Furthermore the ATyS d H does not need any external bridging bars as the load side is connected within the product. This enables to save time during installation.

High-performance switching

The ATyS d H offers high withstand short circuit current ratings of 143 kA Icm (making) and 65 kA for 0.1sec Icw (withstand). Further to its high short circuit withstand, the ATyS d H performance in terms of load switching capacity is AC-33iB (6 x In cos Ø 0.5) without derating.

Safe on-load transfer: I-0-II

The ATyS d H includes two mechanically interlocked switches to ensure fast switching whilst providing a neutral (Off - 0) position. This ensures that the main and alternative power supplies do not overlap.
