Tronic Automatic Transfer Switch 63A Dual Power Supply

Our review

This is a miniature automatic transfer switch from Tronic, rated at 63A, designed to switch a load between a main power source and a standby one. It sits in the PC grade of switches, which the listing notes is not meant for frequent switching, and it is built for AC 50Hz distribution systems. That makes it a fit for a home or small premises where a generator or inverter backs up the grid and you want the changeover handled without manually throwing a breaker. Before buying, confirm your supply is 50Hz and that your total load stays within the 63A rating, since the listing gives no further specifications. Compare it with contactor-based changeover setups and with smaller 6A to 32A units in the same range if your load is light. Also check whether your installation needs a mechanical interlock or a specific pole configuration, as none is stated here. It is available on Sokonia.
