Short DescriptionT5H 630 MCCB PR221DS-LS/I IN=630A 3P 70KA F F
Long DescriptionTmax family is now available as a complete range of moulded case circuit-breakers up to 1600 A. The electric arc interruption system used on Tmax circuit-breakers allows the short-circuit currents of very high value to be interrupted extremely rapidly. The considerable opening speed of the contacts, the dynamic blasting action carried out by the magnetic field and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time, notably limiting the value of the specific let-through energy I2t and the current peak.
