Power Automatic Transfer Switch 4P 100A Rail Mounted Millisecond Fast Switching Controller for PZ30 What it does Automatically transfers power between main supply and generator to maintain continuous power. Acts as a generator changeover switch with integrated AC110V electronic circuit breaker control. Designed for rail mounted installation and direct compatibility with PZ30 controllers. Key benefits Minimizes downtime: millisecondlevel switching reduces interruption time during source changes, protecting sensitive equipment and processes. Reliable changeover: fourpole switching supports threephase plus neutral systems for balanced and safe transfer of loads. Spacesaving installation: rail mounted design fits standard control panels and simplifies wiring and maintenance. Builtin electronic control: AC110V electronic circuit breaker interface provides precise, repeatable switching and easier integration with existing control logic. Clear compatibility: engineered for use with PZ30 transfer controllers to ensure correct operation in matched systems. Important attributes Function: Automatic Transfer Switch for mains to generator changeover with electronic circuit breaker control. Poles: 4P for threephase plus neutral switching. Rated current: 100A continuous handling capability. Control voltage: AC110V electronic control input. Mounting: Rail mounted type, suitable for standard equipment racks and control cabinets. Performance: Millisecond fast switching for rapid response on power loss or restoration. Compatibility: Designed for PZ30 series controllers. How it solves common problems Prevents equipment resets and data loss by restoring power within milliseconds when the primary supply fails. Reduces manual intervention and potential human error associated with manual transfer switches. Protects distribution networks by switching all poles simultaneously to avoid phase imbalance or floating neutrals. Simplifies panel layout and wiring with a rail mounted form factor built for modular control assemblies. Typical applications Small to medium commercial buildings requiring automatic backup between utility supply and standby generator. Industrial control panels where threephase motors and sensitive electronics need uninterrupted power and coordinated switching. Telecommunications or server room power distribution where rapid, reliable transfer is needed to protect equipment and data. Installation and integration notes Mount on standard equipment rail inside the control cabinet for efficient use of space. Use AC110V control wiring compatible with PZ30 controllers for correct switching commands. Ensure system wiring and protective devices are sized for 100A rated current and the connected load. Why choose this model Delivers fast, coordinated fourpole switching with electronic control for modern backup power systems. Engineered for straightforward rail mounted installation and direct compatibility with PZ30 controllers, making it practical for retrofit and installations. Provides a clear, dependable solution where fast automatic changeover and compact mounting are required.
