Tronic Miniature Circuit Breaker, 1 Pole, 63A

Our review

This Tronic miniature circuit breaker is a single-pole unit rated at 63A. In a typical home, single-pole breakers protect the lighting and small appliance circuits, and each one is wired with a live and a neutral conductor. When an overload occurs on the circuit that a single-pole breaker serves, only that breaker trips, leaving the rest of the installation undisturbed. That behaviour makes this type useful where you want faults isolated to one circuit rather than shutting down the whole board. Before buying, confirm the rating and pole count match the circuit you have in mind, and check that your consumer unit accepts the breaker's physical format, since mounting styles differ between brands and ranges. It is worth comparing against other single-pole breakers of the same rating, particularly on breaking capacity and terminal type, because those details decide whether a unit is suitable for your installation. If your circuit needs both live and neutral switched, or you are protecting a high-power appliance, a different breaker type may be the better fit. Available on Sokonia.
