Tronic MCCB 400A 3 Pole, 25kA Breaking Capacity
TSh 541,500
Our review
This is a molded case circuit breaker rated at 400A for three-phase systems, built to interrupt short-circuit currents up to 25kA while maintaining service continuity at 18kA. It suits medium to heavy-duty electrical installations where a single device must protect larger loads, such as distribution boards feeding substantial equipment or sub-panels. Before buying, confirm your system's rated current, voltage, and available fault current match the breaker's ratings, and check that the trip unit and mounting arrangement fit your enclosure. Compare with other 400A MCCBs on breaking capacity, pole configuration, and whether you need adjustable trip settings.
