Tronic Double Pole Isolator 40A, 220-240V AC
TSh 14,500
Our review
A double pole isolator is the switch you install so a circuit or appliance can be shut off completely before anyone works on it. This Tronic unit is rated at 40 amps and 220-240 volts AC, and it breaks both live and neutral rather than one conductor, which is the point of a two pole design. It suits electricians and homeowners wiring in a dedicated isolator for equipment that needs routine servicing, testing or repair, and it is a sensible choice where a single pole switch would leave a conductor still live. Before buying, confirm the load current and supply voltage match the 40A and 220-240V ratings, check the enclosure and wiring method suit your installation, and decide whether you need a two pole device at all. Compare against other isolators by pole count, current rating and build quality. The white and red finish makes the switch position easy to see, and it carries a one year warranty.
