Tronic Automatic Phase Selector CO APS5-100, 100A 3-Phase + Neutral
TSh 141,500
Our review
The Tronic CO APS5-100 is an automatic phase selector built for three-phase installations that also carry a neutral. Rather than relying on a manual changeover, it watches the incoming phases and switches to whichever one sits within the voltage thresholds you define, so connected equipment keeps running when one phase drifts or drops out. It suits homes, shops, small workshops and light industrial sites where single-phase loads are fed from a three-phase supply and voltage swings are a recurring problem. Before buying, confirm your supply arrangement, the current your installation draws, and that your electrician is comfortable setting the thresholds. Compare it with manual changeover switches and simpler voltage protectors: those need someone to act, while this one responds on its own. Also weigh it against automatic selectors from other brands by checking rated current, phase and neutral configuration, and how thresholds are adjusted. It is available on Sokonia.
