Tronic Residual Circuit Breaker, 4 Pole, 100A, AC 240V

Our review

This is a four-pole residual circuit breaker from Tronic, rated at 100A and designed to operate at AC 240V. It is built from PVC and comes in a white finish. A four-pole unit like this is typically chosen for three-phase installations where all live conductors need to be disconnected together, so it tends to suit electricians and property owners working on larger distribution boards rather than simple single-phase home circuits. Before buying, confirm that your supply arrangement and cable sizing actually call for a 100A four-pole device, and check how it will be mounted and wired into your existing board. Compare it with other four-pole breakers by looking at the rated current, voltage and pole configuration, since those are the details that determine whether a unit is right for a given installation. If your setup only needs single-phase protection, a two-pole or single-pole device may be more appropriate. This one is available on Sokonia.
