How to use

Mount the automatic transfer switch on a standard DIN rail in a suitable enclosure and connect the two power sources and the load according to the wiring diagram provided by the manufacturer. Ensure the control (main) voltage supply is AC 220 V for correct automatic operation. After wiring, verify fuse ratings (RT16-00-63A) and perform commissioning tests to confirm correct transfer and return actions under both automatic and manual modes.

Usage recommendations

Install the device in a dry, ventilated electrical cabinet and ensure all connections are made by qualified personnel. Use proper short-circuit protection and observe the rated limits (100 A, 50 kA conditional short-circuit current). Regularly inspect for wear and test transfer operation to maintain reliability.
