Tronic Isolator Triple 125Amps

Our review

This is a triple-pole isolator from Tronic, rated at 125Amps. An isolator is a mechanical switch that separates a circuit or a piece of equipment from its power source, and it does this while sitting in the open position, so the input and output are physically disconnected. That makes it a safety device rather than a control you would use to switch things on and off regularly. It suits electricians, panel builders, and anyone setting up a workshop, pump house, or small industrial installation where a machine needs to be fully isolated before servicing. Because no specifications are listed beyond the rating, check the number of poles, the mounting style, and the terminal arrangement against your existing setup before ordering. Compare it with fused switch disconnectors and enclosed isolators of the same current rating, since those add protection or housing that a bare isolator does not provide. Available on Sokonia.
