Tronic Industrial 3-Pole Circuit Breaker 125A 21kA MCCB
TSh 162,500
Our review
This is a moulded case circuit breaker from Tronic, built as a three-pole unit rated 125A with a breaking capacity of 21kA at 400/415V. That combination points to three-phase work: distribution boards, machine supplies, and larger commercial or industrial installations where a single-phase device would not be appropriate. Before ordering, confirm the current rating matches the load and cable, and that 21kA exceeds the prospective fault current at the point of installation. Also check the trip curve and frame size suit your panel, since MCCBs of this rating vary in those respects. Compare against other 125A three-pole breakers on breaking capacity, pole configuration, and physical dimensions rather than price alone. Available on Sokonia.
