Multi-environment solutions

Automatic transfer switch control units help meet the two-fold need for continuity of service and increased safety.

They are traditionally used in hospitals, public buildings, continuous production processes, airports and military applications.

We have noted, however, that they are increasingly required in new applications such as telecommunications and data processing, or in the management of energy sources, and particularly in the renewable energy sector.

A high-performance range for optimum continuity of service

The new range includes 4 types of automatic control unit, depending on the desired service level and complexity of the installation: advanced management of 3 circuit breakers, advanced management of 5, 3 or 2 circuit breakers, or standard management of 2 circuit breakers.

Designed for single-phase, two-phase and three-phase systems, automatic control units can be used to set the conditions for automatic transfer switching and starting or stopping a generator. They also control phase-to-neutral and phase-to-phase voltage.

They are compatible with DPX³ MCCBs, DMX³ ACBs and CTX³ contactors.

Dedicated accessories

Legrand automatic control units benefit from a high-performance range of accessories.

The power supply module can reduce the number of components and make the installation safer.

Extension modules, once installed at the back of configurable units, can be used to increase the number of inputs or outputs, and also add a communication function.

Finally, USB and Wi-Fi connectors make it easy to set the parameters of configurable units via a computer, tablet or smartphone, without having to cut off the power to the electrical cabinet.
