Color/option: 40A Product overview A keyswitchequipped automatic transfer switch (ATS) designed for diesel generator dual power systems. This 4P ATS supports AC220V operation and is available in multiple ampere ratings: 20A, 40A, 63A, 80A, and 100A. The keyswitch provides secure manual control while the ATS manages automatic transfer between utility power and generator power. Key benefits Secure control and easy operation: integrated keyswitch enables authorized manual intervention and prevents accidental switching. Reliable automatic transfer: switches power sources between mains and generator with a 4pole configuration suitable for singlephase or threephase panel layouts. Flexible compatibility: offered in common AMP ratings so you can match the ATS to the generator and load requirements. Simple replacement and retrofit: designed as a generator parts component for ATS panels, making it suitable for maintenance and upgrades. Stable AC220V operation: rated for standard 220 volt control circuits in generator systems. Important attributes Function: dual power automatic transfer switching with keyswitch control for manual override. Compatibility: compatible with diesel generator dual power setups and ATS control panels that accept a 4P module and AC220V control voltage. Configuration: 4pole design; available ampere options 20A, 40A, 63A, 80A, 100A. Control method: keyswitch for authorized manual switching and secure access. Performance: rated to handle the listed current capacities at AC220V for reliable switching in generator control applications. Typical applications Residential backup power: integrate into a home generator control panel to manage automatic transfer and allow secure manual override during maintenance. Small commercial or workshop installations: use in small businesses where reliable automatic switching and controlled manual access are required. Generator maintenance and panel retrofits: worn or damaged ATS keyswitch modules on diesel generator control panels to restore secure switching functions. Notes Select the ampere rating that matches your generator and load requirements. Installation and wiring should be performed by a qualified technician to ensure correct integration with the ATS control circuit and safety compliance.
