Product overview 4P 160A Automatic Transfer Switch (ATS) for dual power applications. Designed as a replacement or spare part for diesel generator control systems and electric control circuits. Supports single phase and three phase AC configurations and is rated for currents up to 160 A. Key benefits Automatic, reliable changeover between mains and generator power to reduce manual intervention and downtime. 4pole design switches all three phases plus neutral, making it suitable for three phase installations and single phase setups where neutral switching is required. 160 amp rating supports a wide range of small commercial and light industrial loads without the need for oversizing. Designed for integration with generator control panels, circuit breaker assemblies, and electric control circuits for straightforward retrofit or installations. Compact, modular form factor simplifies mounting and wiring in control cabinets or ATS enclosures. Main features Function: automatic transfer switch with dual power changeover capability for diesel generator systems and mains supply. Compatibility: suitable for single phase and three phase AC systems; intended for use with diesel generator control circuits and breakerbased power distribution. Capacity: four poles, rated current 160 A. Operation: automatic switching between source A and source B based on control circuit inputs; compatible with standard generator start and breaker control wiring. Installation: designed for panel or enclosure mounting and for connection to existing control circuitry and breakers. Practical use scenarios Small commercial building backup: automatic transfer between utility supply and onsite diesel generator to restore power for lighting, HVAC, and essential loads during outages. Construction or remote site power: integration with portable diesel generator control panels to provide automatic load transfer for tools and temporary facilities. Equipment and communications shelters: use as a compact ATS module in control cabinets to switch single phase or three phase equipment to standby generator power. Why choose this unit This 4P 160A ATS is a straightforward, applicationfocused component for generator control and power transfer systems. Its fourpole configuration and 160 amp rating make it appropriate for a range of single and three phase installations where automatic transfer between mains and diesel generator is required. It fits into existing control and breaker architectures for easy replacement or upgrade.
