CNC Electric YCQ1B 4 Pole 63A Automatic Transfer Switch (ATS)

Automatic Source Transfer for Three-Phase Backup Panels

The CNC Electric YCQ1B 4 Pole 63A Automatic Transfer Switch is an option for appropriately designed three-phase boards requiring changeover between main and standby supplies. Automatic and manual operating modes provide source-transfer control while retaining a rotary handle for manual switching.

In a compatible backup installation, the ATS can transfer the connected load to an available standby supply when the main supply fails. The front-panel indicators and clearly marked source and OFF positions help identify operating status.

Applications and Installation

For compatible generator backup panels and appropriately sized commercial or workshop distribution boards. Motor loads, pumps and lift systems require professional assessment of starting currents, transfer requirements and equipment compatibility before selection.

The ATS transfers between available power sources; it does not generate backup power or guarantee uninterrupted supply. Have a qualified electrician confirm source compatibility, cable sizing, protection, earthing and the manufacturer's wiring diagram before installation.
