Tronic Industrial 4-Pole Circuit Breaker – 315A, 21kA MCCB
TSh 444,000
Our review
This Tronic moulded case circuit breaker is a four-pole unit rated at 315A with a breaking capacity of 21kA at 400/415V. It is built for heavy-duty three-phase circuits, so it suits industrial plants, commercial buildings and infrastructure projects where large motors, distribution boards or main feeders need dependable protection against overloads, short circuits and other electrical faults. Before buying, confirm that your system voltage and expected fault level fall within the 400/415V and 21kA figures, and check that the frame size, pole configuration and trip characteristics match your installation drawings. Also verify the mounting arrangement and terminal sizes against your cables and busbars. Compared with smaller MCCBs or miniature circuit breakers, this unit offers a much higher current rating and breaking capacity, making it a better fit for main incoming or sub-main positions rather than final circuits. It is available on Sokonia.
