Tronic MCCB 250A 3 Pole Adjustable Trip Circuit Breaker

Our review

This is a molded case circuit breaker from Tronic, rated at 250 amps across three poles, with adjustable trip settings. That adjustability is the detail worth pausing on: it lets the breaker's tripping behaviour be tuned to the circuit it protects, which matters in installations where a fixed-trip device would either nuisance-trip or fail to protect properly. It suits electricians, panel builders, and facility maintenance teams working on three-phase distribution boards, motor circuits, or feeder protection where currents sit in the low hundreds of amps. Before buying, confirm your system voltage and frequency fall within the range the breaker supports, check that 250A and three poles match your load and cabling, and verify the trip range covers the settings your design calls for. Compare against other MCCBs of the same rating on breaking capacity, trip unit type, and terminal size, since those decide whether it fits your enclosure and fault level. If you are unsure, have a qualified person confirm the selection against your single-line diagram. Available on Sokonia.
