ABB 100 amps T max 4 pole formula

Tmax T4, T5 and T6 are the moulded-case circuit breakers with the best performance/size ratio on the market. Their application possibilities are practically unlimited, thanks to their dedicated and specific ranges, advanced electronics, as well as a complete and standardized Range of accessories. The top quality materials and innovative construction techniques used by ABB SACE mean Tmax circuit breakers can guarantee truly exceptional performances, with a really high rated current/ volume ratio. For example, T4 and T5 guarantee a breaking capacity up to 200 kA at 415 VAC and an extraordinary 80 kA at 690 VAC Moreover, they complete the Range of applications up to 1150 V in alternating current and 1000 V V in direct current. The series of electronic trip units, equipped with latest generation technology, offers solutions exclusive to ABB. T4, T5 and T6 have the same depth, simplifying their positioning in the switchboard compartments, and also have a complete, standardized and unified Range of accessories available, simplifying selection, making them flexible to use and reducing stocks.
