Tronic Surface Isolator 4-Pole 32 Amps 415V

Our review

This Tronic isolator is a four-pole, 32 amp surface-mounted switch rated for 415 volts. Its job is straightforward: it lets you fully de-energize a circuit before anyone services or maintains it, which is why isolators sit apart from ordinary switches in an installation. The four-pole format suits three-phase circuits where all live conductors need to be disconnected together, and the 32A rating points to use on moderately loaded final circuits rather than heavy distribution boards. Surface mounting means it fixes onto the wall or panel face rather than recessing, which helps in retrofits and plant rooms where chasing into a wall is impractical. Before buying, confirm your supply is genuinely three-phase at 415V, that 32A covers the circuit's load with some margin, and that your enclosure or mounting position gives the switch room to operate. Compare against enclosed versus open isolators, rotary versus lever operation, and lockable designs if you need to padlock the supply off during maintenance. If your circuit is single-phase, a two-pole unit is usually the better match. Available on Sokonia.
