63A Three Phase Automatic Transfer Switch with Adjustable Voltage Protection AC110V DIN Rail Mounted

Model CHLTGX3 Three Phase Automatic Transfer Switch Style AC110V Overview The CHLTGX3 automatic transfer switch provides uninterrupted power transfer between a primary supply and a backup supply. When the main supply fails or its voltage moves outside set thresholds, the ATS transfers the load to the selected standby source and automatically returns to the main supply when conditions recover. Priority is L1 then L2 then L3. Key benefits Continuous power: Automatic transfer prevents unplanned interruptions by switching loads to a standby source when mains voltage is abnormal or lost. Flexible configuration: Choose the priority among mains, generator, and inverter and set voltage thresholds and timing to match site requirements. Precise protection: Adjustable under voltage, over voltage, and overcurrent parameters help protect equipment and limit nuisance transfers. Durable construction: A flameretardant PC cover and compact DIN rail design make the unit suitable for control panels and distribution enclosures. Easy integration: Standard power terminals and compact size simplify installation into existing three phase systems. Main functions and features Automatic transfer: Detects supply abnormality and switches load to standby source; returns automatically after main supply recovery. Priority control: Userdefined priority with L1 , followed by L2 and L3. Configurable switching thresholds: Set under voltage and over voltage trigger points to suit generators, inverters, and mains supplies. Adjustable timing: Auto reclosing delay and priority stage delay adjustable from 1 to 600 seconds; default auto reclosing delay 30 seconds. Protection timing: Overvoltage trip delay 0.1 s; at or above 350 V trip delay 0.02 s. Undervoltage trip delay 0.1 s; at or above 350 V trip delay 0.02 s. Performance ratings: Rated operating current 63 A; maximum operating current 80 A. Terminals: N, L1, L2, L3 for straightforward three phase connections. Installation: Mounts on a standard 35 mm DIN rail. Environment: Operates from 25 C to +50 C at altitudes up to 2000 m; relative humidity up to 50 percent at 40 C non condensing. Wiring: Accepts wire sizes from 0.5 mm2 to 1 mm2. Pollution degree 3. Adjustable parameters Transfer time and reset time within specified ranges.
