Tronic Industrial 3-Pole Circuit Breaker 100A 18kA MCCB

Our review

This is a moulded case circuit breaker from Tronic, rated 100A across three poles, intended to protect three-phase circuits. Its 18kA interrupting capacity at 400/415V means it can clear heavy fault currents, so it fits factories, commercial buildings, and larger residential installations where a main or distribution breaker has to handle serious short-circuit energy. Before buying, confirm your system voltage, the actual load current, and the prospective fault level at the point of installation; the breaker's rating must cover the fault current, and cable sizing and coordination with upstream devices matter too. Compare it with other 100A MCCBs on breaking capacity, trip unit type, and whether your panel accepts its frame size, since those details decide suitability more than brand alone. It is available on Sokonia.
