Tronic Industrial 3-Pole Circuit Breaker – 630A, 21kA MCCB
TSh 510,000
Our review
This Tronic moulded case circuit breaker is a three-pole unit rated at 630A with a 21kA breaking capacity, built for high-capacity protection of large three-phase electrical systems. It suits industrial plants, commercial complexes and infrastructure projects where a single device must carry heavy current and still interrupt a serious fault. Before buying, confirm your system's voltage, the prospective short-circuit current at the installation point, and whether your panel accepts this frame size, since a 21kA rating is only adequate if it exceeds the fault level. Compare with other 630A MCCBs on breaking capacity, trip unit type and pole configuration, and check that the trip characteristics match your coordination study. A qualified electrician should verify suitability for your installation.
