Specifications: · Item Type: Double Power Automatic Transfer Switch · Material: PC (Polycarbonate) · Rated Voltage: 400V · Frequency: 50/60Hz · Number of Poles: 4 · Segmentation Capacity: 35KA · ATSE Grade: CB · Rated Current: 63A Working Principle: This automatic transfer switch uses the A phase and N line voltage signals from the common and standby switch inlet ports to control power source transfer. Under normal conditions (AC 190-240V at common switch), the common power supply is prioritized and the common switch closes while standby switch remains open. If the common power supply voltage fails, the switch automatically transfers to the standby power supply, closing the standby switch to maintain uninterrupted power. Manual operation mode is also supported regardless of voltage availability, allowing manual switching by rotating the handle to toggle between common and standby power circuits. Package Includes: · 1 x Double Power Automatic Transfer Switch This Double Power Automatic Transfer Switch combines safety, durability, and smooth operation to provide a dependable solution for automatic and manual power source management. Its advanced interlocking mechanism and versatile control options make it essential for ensuring continuous power supply in various residential and industrial applications.
