Automatic Transfer Switch for Diesel Generators, Dual Power, 4P, AC220V Description A reliable automatic transfer switch (ATS) designed for dual power systems with diesel generators. The 4 pole design supports three phase systems with neutral and enables automatic transfer between mains and generator supply. Available in multiple current ratings to suit different load requirements. Includes keyswitches for manual control and improved transfer management. Key benefits Automatic and manual transfer: Automatically switches supply between mains and generator for uninterrupted power. Keyswitches provide a secure manual override for maintenance or special operating conditions. Flexible current ratings: Available in 63A, 80A, and 100A options to match different load sizes and installation needs. Four pole design: 4P configuration supports three phase systems with neutral, suitable for most commercial and industrial generator setups. Standard control voltage: Coil and control circuits designed for AC220V control systems for straightforward integration. Practical and durable: Built for routine generator switching tasks, reducing downtime and simplifying backup power management. Main features Function: Dual power automatic transfer switch for automatic and manual transfer between mains and diesel generator supplies. Poles: 4P suitable for three phase plus neutral connections. Current ratings: 63A, 80A, 100A options. Control voltage: AC220V. Keyswitches: Builtin keyswitch control for manual operation and locked access to transfer functions. Compatibility: Intended for use with diesel generator sets and standard mains supply systems operating at matching voltages. Use scenarios Commercial building backup: Switch critical building circuits automatically to a diesel generator during mains failure, with keyswitch for maintenance isolation. Construction site power management: Provide secure, switchable power to site distribution panels where reliable changeover is required between site mains and generator. Small industrial plant or workshop: Protect production equipment by ensuring rapid transfer to generator supply and allowing controlled manual operation when needed. Notes for installers Verify system voltage and phase configuration before selecting the appropriate amp rating. Ensure wiring and overcurrent protection comply with local electrical codes. Use the keyswitch for controlled manual transfers and servicing to avoid unintended switching.
