63A 4 Pole Automatic Transfer Switch AC230V/400V Dual Power for Generator Backup

YCQ3B63 Dual Power Transfer Switch 2P / 4P 63A 50/60Hz AC230V / 400V What this product does The YCQ3B63 is an ATS dual power transfer switch designed to switch between two power sources quickly and reliably. Available in 2P and 4P configurations, rated at 63A and compatible with 50 Hz or 60 Hz systems, it supports AC230V and AC400V power networks and functions as an electrical selector switch for safe, controlled transfer of supply. Key benefits Ensures continuous power: Automatically or manually transfers load between primary and secondary sources to minimize downtime. Clear compatibility: Rated for 63A and suitable for 50 Hz or 60 Hz systems at AC230V and AC400V, making it suitable for common single phase and three phase applications. Flexible configurations: Choose 2P for single phase applications or 4P for three phase systems and neutral switching. Reliable switching: Designed for stable operation in repeated transfer scenarios, reducing the need for manual intervention. Easy integration: Compact form factor and standard mounting enable straightforward installation into control panels and distribution boards. Important features and attributes Model: YCQ3B63 Poles: 2P and 4P options; product listing includes 4P electrical selector switch variant Rated current: 63A Frequency: 50/60Hz Rated voltage: AC230V and AC400V Function: Dual power transfer and electrical selection between two supply sources Operation modes: Automatic transfer and manual override options for maintenance and testing Design: Compact, panelmount friendly housing for electrical distribution systems How it solves common problems Prevents service interruptions by switching to backup power when the main supply fails. Reduces manual intervention and human error by providing automatic switching and clear selector control. Protects downstream equipment from prolonged outages by restoring supply quickly through the alternate source. Typical applications Backup generator switching for small commercial buildings and workshops to transfer loads from mains to generator. Residential or light industrial main and emergency supply switching for lighting, HVAC, and essential circuits. Equipment rooms and control cabinets where three phase systems require coordinated switching of all poles using the 4P selector switch. Selection and installation tips Match the pole configuration to your system: use 2P for single phase systems and 4P for three phase plus neutral switching. Confirm system voltage and frequency compatibility before installation: AC230V or AC400V at 50 Hz or 60 Hz. Provide space for access and maintenance; include a suitable upstream protection device rated for 63A. The YCQ3B63 provides a practical, compact solution for reliable transfer between two power sources in residential, commercial, and light industrial installations.
