Tronic Triple Pole 20A MCB

Our review

This is a Tronic miniature circuit breaker rated at 20 amps with a triple pole configuration, meaning it can switch or protect three separate lines together. That makes it relevant for three-phase circuits rather than the single-pole breakers most people see in a basic home distribution board. Before buying, confirm your board actually takes a triple pole device and that 20A matches the circuit you are protecting, since the wrong rating or pole count will not fit or will not protect correctly. Also check whether your existing breakers are the same type and breaking capacity, because mixing types in one board is not ideal. Compare against other triple pole breakers by looking at rated current, trip curve and physical size. The listing summary on Sokonia describes a touch sensor mirror light, which does not match the product title, so treat the title and rating as the reliable details and verify everything else with the seller before ordering.
