Tronic Surface Isolator 4-Pole 20 Amps 415V

Our review

This Tronic isolator is a four-pole, 20 amp surface-mounted switch rated for 415 volts. Its job is straightforward: it lets you fully de-energize a circuit so someone can work on it safely. That makes it relevant to electricians, maintenance staff, and anyone setting up or servicing three-phase equipment where a reliable means of isolation is needed. Because it is a surface type, it mounts on the wall rather than recessing into it, which suits workshops, plant rooms, and similar spaces. Before buying, confirm the number of poles and the current rating match your circuit, and check that the voltage rating covers your supply. Compare it with other isolators by enclosure type, pole count, and whether the switching arrangement fits your wiring. If you need a basic, clearly rated isolation point rather than a combined breaker or distribution board, this is the kind of component to consider. It is available on Sokonia.
