Dual Power Automatic Transfer Switch 2P, 3P, 4P options 125A rated for fast, reliable transfer between mains and generator Compatible with 110V and 220V generator systems; 3P version rated 400V Key benefits Continuous power without manual intervention: automatic transfer in milliseconds maintains power to connected loads during mains failure. Flexible configurations: available in 2 pole, 3 pole, and 4 pole versions to match single phase and three phase installations. Robust current capacity: 125A rating supports a wide range of residential and commercial generators and load requirements. Clear compatibility: designed for use with uninterruptible millisecond generator setups at 110V and 220V. 3P variant supports 400V systems. What this product does and why you need it Automatically senses loss of utility power and switches supply to the generator in milliseconds, eliminating the need for manual transfer and reducing downtime. Reinstates mains supply seamlessly when utility power returns, restoring normal operation without operator action. Suitable where uninterrupted power is important for equipment operation, safety, or convenience. Performance and key attributes Function: automatic transfer between two power sources for uninterruptible operation. Configurations: 2P, 3P, 4P to suit different wiring requirements and system types. Electrical ratings: 125A continuous current rating; compatible voltages include 110V, 220V and 400V for the 3P version. Installation: intended for integration with generator and mains distribution systems that require fast, automatic switching. Typical applications Home backup power systems that support refrigerators, lighting, and essential circuits during outages. Small commercial sites, workshops, and retail locations using a generator to keep critical equipment running. Remote installations and telecommunications sites where automatic restoration of power prevents service interruption. Notes for installers Select the appropriate pole configuration to match the site wiring and neutral requirements. Ensure the switch rating aligns with generator output and load calculations before installation. Follow local electrical codes and standard installation practices when integrating into distribution panels.
