Dual power automatic transfer switch 4P 63A (CB ATS) for threephase fourwire systems Overview This automatic transfer switch provides reliable, intelligent switching between two power sources for threephase fourwire installations. Rated at 63A and configured as a 4pole device, the CB ATS model monitors source voltages and performs automatic transfer to maintain continuous power where needed. Key benefits Continuous power protection: Automatically detects loss or abnormality on the primary source and transfers load to the secondary source to minimize downtime. Simple compatibility: Designed for standard threephase fourwire networks and commonly used with utility mains and standby generators. Clear capacity: 63A rated current and 4pole configuration support balanced threephase loads and neutral continuity. Intelligent switching: Builtin control logic monitors both inputs and executes reliable, orderly transfers to protect connected equipment. Robust construction: Engineered for integration into electrical distribution systems to support commercial and light industrial applications. Core functions and attributes Function: Automatic transfer between two independent power sources for threephase fourwire circuits. Pole configuration: 4P for three phases plus neutral. Rated current: 63A for continuous load handling within specified capacity. Model identification: CB ATS series, dual power automatic transfer switch with intelligent switching. Compatibility: Intended for use with utility mains, standby generators, and other compatible threephase fourwire supplies. Performance focus: Fast detection and transfer to reduce interruption time and maintain load continuity. Typical applications Backup power switching for small commercial buildings and retail stores where generator standby is used for outages. Industrial equipment and motor loads in workshops or light manufacturing that require uninterrupted threephase supply. Critical facility support such as pump stations, lighting circuits, or control panels where seamless transfer between two power sources is required. Installation and use notes Integrates into standard threephase distribution panels and switchgear assemblies. Verify system wiring and protective devices are appropriate for a 63A 4pole transfer switch before installation. Test and the transfer operation under controlled conditions to confirm correct behavior with the chosen primary and secondary sources. This dual power automatic transfer switch 4P 63A (CB ATS) delivers dependable, intelligent switching for threephase fourwire systems, providing clear capacity and straightforward compatibility for a range of commercial and light industrial power continuity needs.
