Product: RDS3125D/4P ATS Generator Dual Power Automatic Transfer Switch with Control Panel and Circuit Breaker Color: 125C with accessory Electric Controls Key benefits Automatic and reliable switching between mains and generator power to minimize downtime and maintain continuous operation. Integrated control panel streamlines monitoring and operation, reducing installation complexity and the need for separate controllers. Built in circuit breaker options for 63A, 100A, and 125A let you choose the capacity that matches your electrical load. C and D curve breaker types offer selectable trip characteristics to match motor starting currents and load inrush behavior. Four pole design supports three phase systems with neutral switching for safer and more complete isolation. What it does and why you need it Performs automatic transfer of electrical supply between utility and backup generator, removing the need for manual switching during power interruptions. Protects connected equipment from prolonged outages by restoring power quickly and preventing unintended backfeed. Centralizes control and protection in one compact module, simplifying wiring and maintenance. Main attributes Model: RDS3125D/4P ATS Function: Dual power automatic transfer switch with integrated control panel Poles: 4P for three phase systems with neutral Circuit breaker ratings: available in 63A, 100A, 125A Breaker types: C type and D type trip curves to suit different load characteristics Color and accessories: supplied in color code 125C with accessory; includes Electric Controls components Performance: designed for reliable automatic operation under normal load conditions for backup power switching Compatibility and installation notes Compatible with standard generator sets and utility supply systems in three phase installations. Select breaker rating and trip curve based on load profile and motor starting requirements. Intended for installation in electrical distribution panels or enclosures by qualified personnel following local wiring practices. Practical applications Commercial backup power: automatic switching for retail outlets, offices, and small warehouses to maintain lighting and critical systems during outages. Industrial equipment: protecting production lines and motor loads where inrush currents require C or D type breakers. Remote sites and generator installations: reliable transfer for telecommunications huts, pump stations, or temporary power setups. What sets it apart Combination of automatic transfer functionality, a built in control panel, and selectable circuit breaker ratings provides a compact, adaptable solution for many backup power needs. Four pole configuration ensures neutral is switched together with phases for comprehensive isolation. Ordering guidance Choose the appropriate circuit breaker rating 63A, 100A, or 125A and select C or D trip curve according to equipment startup characteristics. Confirm color code 125C and included accessory set to match site requirements. This device provides a practical, integrated solution for automated transfer and protection of three phase power between utility and generator sources.
