Automatic Transfer Switch 4P 63A

The YCQ4 is the newest and most compact solution for automatic switching between two power sources in three-phase systems. It provides automatic transfer between grid power and a backup source (generator or solar power) in a very small space inside the board. It switches instantly to protect your home appliances from long outages while maintaining the highest electrical safety standards.

⚡ Features:

Very compact design: saves a lot of space in the distribution board thanks to its small size compared with traditional ATS switches.

Instant automatic transfer: switches between sources within fractions of a second, reducing the chance of sensitive electronics restarting.

Mechanical and electrical protection: an interlock prevents the two sources from touching, protecting the generator and the grid from short circuit.

Manual mode: a front switch toggles between automatic and manual modes, giving you full control during maintenance.

Easy installation: mounts directly on standard DIN Rail without major changes to the board.
