Tronic Isolator 4-Pole 16Amps

Our review
The Tronic Isolator 4-Pole 16Amps is a manually operated mechanical switch built to isolate a problem area in a substation or similar electrical setup. Its job is straightforward: separate the section that needs repair from the healthy part so work can proceed without exposing the rest of the system to a serious fault. The four-pole configuration means it switches all poles together, which suits three-phase circuits where you want a clean, complete break rather than a partial one.
This isolator fits electricians, maintenance teams and facility managers who need a visible, manual means of disconnection before servicing equipment. It is not a substitute for a circuit breaker or fuse; an isolator does not trip automatically on overload or fault current. Before buying, confirm the number of poles and the current rating match your circuit, check the mounting style and terminal arrangement suit your panel, and make sure the enclosure or installation environment is appropriate. Compare it with other 16A isolators on pole count, build quality and how it mounts, since those details decide whether it fits your setup.
