Electrical panels for switching and protection of generator sets — Socomec and ABB

In this section, you will find electrical components for automatic switching between the utility grid and a generator set, as well as for protecting the installation: complete ATS panels, motorized switches, power jumpers, and circuit breakers from the following brands: Socomec y ABB. We ship throughout Europe and internationally.


Complete ATS Panels — Socomec

The ATS (Automatic Transfer Switch) panels These are automatic transfer switches that manage the transfer of load between the utility power grid and the generator set. In the event of a grid failure, the ATS panel detects the loss of voltage, sends a start signal to the generator set, transfers the load to the generator once it is ready, and automatically transfers the load back to the grid when power is restored. The entire process occurs without manual intervention. Four-pole (4-pole) configuration for three-phase installations with a neutral.

  • Socomec ATS Panel 4x40A — for installations up to 40A per phase
  • Socomec ATS Panel 4x63A — for installations up to 63A per phase
  • Socomec ATS Panel 4x100A — for installations up to 100A per phase
  • Socomec ATS Panel 4x160A — for installations up to 160A per phase

ATyS Motorized Switches — Socomec

ATyS switches are the motorized switching components for those who prefer to assemble or expand their own ATS panel rather than purchase the complete unit. Available in two series based on current rating:

ATyS dM Series (40 to 160 A):

  • Socomec ATyS dM 4P 40A Motorized Switch 4P 40A
  • Socomec ATyS dM 4P 63A Motorized Switch
  • Socomec ATyS dM 4P 100A Motorized Switch
  • Socomec ATyS dM 4P 160A Motorized Switch

ATyS D Series (250 to 630 A, for higher-capacity installations):

  • Socomec ATyS D 4P 250A Motorized Switch
  • Socomec ATyS D 4P 400A Motorized Switch
  • Socomec ATyS D 4P 630A Motorized Switch

ATyS Power Bridges — Socomec

A component that complements the motorized switch, required to complete the installation of the power contacts in the ATS panel.

  • Socomec ATyS 4P 40-125A Power Bridge
  • Socomec ATyS 4P 160A Power Bridge
  • Socomec ATyS 4P 250A Power Bridge
  • Socomec ATyS 4P 400A Power Bridge
  • Socomec ATyS 4P 630A Power Bridge

ABB Circuit Breakers

ABB's Tmax XT series four-pole circuit breakers for general installation protection, with a TMG thermal-magnetic unit.

  • ABB 160A 4P TMG XT2N Circuit Breaker
  • ABB 250A 4-pole TMG XT3N Circuit Breaker
  • ABB 630A 4P XT5N Circuit Breaker

A complete set or individual components?

If you need a ready-to-install ATS panel, the complete Socomec models (4x40A to 4x160A) are the quickest solution. If you already have an enclosure and want to assemble or repair your own panel, the ATyS motorized switches and their corresponding power bridges allow you to build a custom solution, including higher current ranges (up to 630A) not available in the complete panels. If you have questions about what current rating you need, contact us at based on the unit's power and the system's specifications.


Do I also need a controller for the ATS panel?

These switching devices require an external control signal to manage the generator set’s start-up and shutdown. If your generator set already has a control panel with an AMF function (DSE, ComAp, SVE…), the ATS panel works with the signal from that control panel. If you also need the control module, see our section on power plants for generator sets.
