Function

COMO CS are manually operated multi-pole transfer switches. They ensure switching, transfer
of sources or transfer of two low voltage circuits on load as well as their safe disconnection.

Advantages

Simple installation

The “quick fix” allows significant time saving
in fixing the handle to the device. The devices
sold in enclosed version are ready for
installation.

Effective in all circumstances

The devices are available with 3 standard
switching types that can cover a wide variety
of applications:

- I-II

- I-0-II

Quick mounting

The accessories offered are common to all
the products in the range. The products are

- I-0-II with bypass
Please consult us for adaptations to specific

wiring diagrams.

designed for installation:

- on the rear of the cabinet on a backplate,

- on the rear of the cabinet on a DIN rail,
