The 63A Automatic Transfer Switch and Protector automatically or manually transfers a single-phase load between two 220V AC power sources, such as utility power and a backup inverter or generator. It switches both the live and neutral conductors and provides adjustable electrical protection with a clear digital display.
Key Features
- Two-pole switching: disconnects both Live and Neutral
- Automatic transfer or manual source selection
- Selectable priority source: L1, L2 or non-priority mode
- Displays the voltage of both sources and the load current
- Adjustable overvoltage, undervoltage and overcurrent protection
- Adjustable power-on, recovery and transfer timing
- High-temperature protection with fault indication
- Voltage and current calibration settings
- Compact DIN-rail mounting
