Automatic Transfer Switch 63A Three Phase ATS Din Rail Mounted Generator Changeover with MultiProtection Description

W2R3P220V Din Rail Mounted Automatic Transfer Switch Three Phase ATS Overview The W2R3P Din Rail Mounted Automatic Transfer Switch is a compact threephase ATS designed for automatic transfer between city power and backup generators. Available in current ratings 25A, 40A, 63A, and 100A, this mini dual power automatic transfer switch provides uninterrupted power transfer and reliable protection for residential and light commercial electrical systems. Key benefits Continuous power supply: Automatically transfers to backup power when the normal supply is abnormal, then switches back when normal supply is restored to maintain continuity. Compact, easy installation: Din rail mounting and small footprint simplify installation and integration into existing control panels. Robust protection: Builtin protection against short circuit, overload, phase loss, and under voltage helps protect connected loads and power sources. Durable construction: Housing made from flameretardant plastic with good insulation and temperature resistance for safe, longterm operation. Main features Model and voltage: W2R3P220V, threephase DIN rail mounted ATS for 220V systems. Current options: Available for 25A, 40A, 63A, and 100A applications. Common configuration example: 3P 63A. Automatic operation: Detects abnormal city power and switches to backup power immediately, then returns to normal power automatically when restored. Protection functions: Short circuit protection, overload protection, phase loss detection, and undervoltage protection. Materials and build: Flameretardant plastic enclosure for good insulation and heat resistance. Size and handling: Compact design for easy carrying, storage, and panel mounting. Important installation and operating notes Rated voltage requirement: Both common and backup power supplies must be within 85 percent to 110 percent of the rated voltage. Minimum current: The current on each supply must not be less than 5A. If current is below 5A the coil may overheat or be damaged. Unstable city voltage: If local supply is unstable, install appropriate voltage protection devices in the system to prevent coil overheating and improve reliability. Applications and use scenarios Residential backup power: Automatic switching between utility power and a home generator to keep essential circuits such as lighting, refrigeration, and communication equipment powered during outages. Small commercial premises: Protection and automatic transfer for shops, small offices, or remote sites that require continuous operation of point of systems, refrigeration, or lighting. Light industrial control panels: Integration into control cabinets to manage power transfer between grid and standby generators for noncritical machinery and process equipment. Technical compatibility Designed for threephase systems and compatible with standard generator and municipal power sources within the specified voltage and current ranges. Mounts on standard DIN rail for compatibility with common electrical panels and enclosures. What this product solves Eliminates manual switching between power sources to reduce downtime and human error. Provides faster transfer to backup supply to minimize interruption to critical loads. Adds protection functions to safeguard connected equipment from common electrical faults. Ordering information Model: W2R3P220V Available current ratings: 25A, 40A, 63A, 100A Example configuration: 3P 63A (threepole, 63 amp) Always verify system voltage and current requirements before installation and follow local electrical codes and practices during setup.
