Tronic Single Pole 16A MCB Circuit Breaker

Our review

This is a single-pole miniature circuit breaker rated at 16 amps, made by Tronic. In a typical home it is the device that protects one lighting run or a small appliance circuit, and it works with one live and one neutral conductor. When a fault or overload occurs on that circuit, only this breaker should trip, leaving the rest of the installation energised. It suits anyone replacing a failed breaker of the same rating or adding a new final circuit, though the work should be done by a qualified electrician. Before buying, confirm the 16A rating matches the cable size and load on the circuit, and check that the physical mounting and terminal layout suit your existing distribution board. Compare it with other single-pole breakers of the same rating, particularly on breaking capacity and trip curve, since those determine how it behaves under fault conditions. Available on Sokonia.
