Dual Power 4 Poles Changeover Switch Transfer Switch ATS 800A Overview A 4pole automatic transfer switch designed to switch a connected load between two power sources. Rated for 800 A continuous current, the ATS 800A provides uninterrupted switching for 3phase systems with neutral. It is built for integration into commercial and industrial electrical installations where automatic and safe changeover between mains and backup power is required. Key benefits Automatic and fast transfer between primary and secondary power sources, reducing downtime during power interruptions. current capacity for heavy loads, suitable for large electrical distribution panels and equipment. 4pole configuration supports 3phase plus neutral installations, ensuring complete phase switching and load protection. Clear function and compatibility make system design and commissioning straightforward. Main features and attributes Function: Automatic transfer switch that detects source failure and shifts the load to the alternate source, then returns when the primary source is restored. Poles and rating: 4 poles for 3phase plus neutral operation, rated for 800 A continuous current. Compatibility: Designed for integration with generators, mains supply, and inverter systems in 3phase power setups. Suitable for use with distribution panels and switchgear sized for 800 A. Construction: Heavyduty electrical contacts and durable enclosure designed for electrical installation environments. Terminals sized for current conductors. Performance: Engineered for reliable switching under load conditions appropriate to the 800 A rating, with mechanisms suitable for frequent changeovers in backup power scenarios. Installation: Intended for fixed panel or switchboard mounting with accessible terminal connections. Compatible with common control and sensing circuits used in automatic transfer applications. Maintenance: Serviceable design to allow inspection and replacement of wear components where applicable. Practical applications Commercial buildings: Automatic transfer between utility mains and a standby generator to maintain lighting, HVAC, and critical services during outages. Industrial plants: Switching process and motor loads between primary supply and backup systems to avoid production interruptions. Data centers and server rooms: Integration with backup generator and UPS systems to protect computing equipment and maintain continuous operation during power events. Why choose this model Specifically sized for larger 3phase installations requiring an 800 A transfer capability. Full 4pole switching ensures neutral continuity and balanced control across all phases. Suitable for integration into existing switchboards and control schemes where automatic source selection is required. Part identification Part name: Dual Power 4 Poles Changeover Switch Transfer Switch ATS 800A Part number: ATS 800A Installation notes Verify system voltage and compatibility with upstream protection devices and busbar arrangements before installation. Ensure cable and terminal sizing match the 800 A rating and local electrical regulations. with appropriate control logic and sensing setpoints to match the characteristics of the primary and secondary sources. This transfer switch provides a practical solution for automatic power changeover in 3phase systems that require a 4pole, 800 A switching device.
