Tronic Industrial 3-Pole Circuit Breaker – 500A, 21kA MCCB
TSh 506,500
Our review
This is a moulded case circuit breaker from Tronic, built as a three-pole unit rated at 500A with a breaking capacity of 21kA at 400/415V. It is aimed at high-capacity three-phase circuits, so it fits industrial plants, commercial buildings and infrastructure work where large loads need protection against overloads, short circuits and severe faults. Before buying, confirm your system voltage and the fault level at the point of installation, because the 21kA rating must meet or exceed what the supply can deliver. Also check the frame size and trip unit type you need, since MCCBs of this rating come in fixed and adjustable versions, and the busbar or cable lugs must match the terminal arrangement. Compare with other 500A three-pole breakers on breaking capacity, trip settings and whether you need thermal-magnetic or electronic protection. It is available on Sokonia.
