Strong Points

Function

ATyS t M are modular automatic transfer switches with positive break indication. They are 4 pole (three-phase) devices.
They have all the functions of the ATyS d M together with an integrated controller, giving them automatic features dedicated to mains/mains applications. They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.

Advantages

Quick start

ATyS t M transfer switches offer significant time saving during commissioning (the process takes 2 to 3 minutes). Thanks to
the design that allows commissioning through just one potentiometer and four DIP switches, a screwdriver is all that is required to configure the parameters.

Dedicated to three-phase mains/mains applications

The ATyS t M integrated controller has been designed to provide all the functions necessary for these applications (operation
with or without priority, preferred source selection) together with the monitoring of the voltage and frequency of both sources for
three-phase networks.

Secure programming

To ensure that the correct configuration is maintained an optional sealable cover can be fitted in order to avoid any unintentional modifications to the programming.

Secure

ATyS t M have both electrical and mechanical interlocks for optimum security. They also feature a positive break indicator, confirming switch position with dual mechanical indicators for increased safety.

High-speed transfer

ATyS t M devices are based on a coil solution with rotating contacts, therefore ensuring an extremely short black-out duration (< 90ms).

Superior electrical performance

ATyS t M devices are compliant with IEC 60947-6-1, the standard governing transfer switches. Their AC-33B properties of up to 125 A mean you can use the same product for resistive and inductive loads.

Immune to voltage fluctuations

The power supply of the ATyS t M is only active during transfer. As the product is based on stable positions, it is not affected by network voltage fluctuations.
