Dual power automatic transfer switch 4P, 125 A Description A compact 4P dual power automatic transfer switch designed for reliable transfer between two power sources. The unit can operate automatically or manually to improve conversion rates and maintain continuity of supply when switching between mains and backup power. Key benefits Continuous power availability: Automatically switches between primary and secondary power sources to minimize supply interruption. Flexible control: Supports automatic operation for unattended switching and manual operation for testing or maintenance. current capacity: Rated working current of 125 A to handle mediumduty electrical loads. Broad system compatibility: Works with common supply configurations and voltage levels used in industrial and commercial environments. Robust electrical isolation: Insulation voltage 690V AC helps maintain separation between circuits under normal conditions. Surge tolerance: Impactresistant voltage 8kV provides resistance to voltage transients. Technical specifications Size: 4P Color: Ac 400v Rated Voltage: 220/380V Rated working voltage: 400V AC Rated working current: 125 A Insulation voltage: 690V AC Impactresistant voltage: 8kV Mode: Dual power automatic transfer switch, can be operated automatically or manually to improve conversion rates Applications and scenarios Small commercial buildings: Automatically switch to backup generator power during mains outages to keep lighting and essential systems running. Light industrial or workshop environments: Provide reliable transfer between utility power and standby generation for motors, compressors, and control systems. Communication and utility rooms: Maintain continuous power to critical control panels and network equipment during planned maintenance or unexpected supply interruptions. Operation and installation notes Designed for use within the specified voltage and current ratings. Confirm compatibility with the facility power scheme before installation. Manual control provides a simple way to test switching sequences and perform maintenance without interrupting operation. Installation should follow applicable wiring practices and be performed by qualified personnel. This transfer switch combines automatic convenience and manual control in a 4P package, offering straightforward integration into systems that require reliable switching between two power sources.
