Feature of Tmax MCCB, Tmax moulded-case circuit-breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety guarantees for the operator. In addition to being ideal for the secondary distribution of alternate and direct current, they feature dedicated solutions for all application requirements, Moulded-case circuit-breakers can be used in low voltage civil and industrial installations with 1 to 3200A operating current. The Tmax family includes 9 circuit-breaker sizes in three- or four-pole versions:- XT1, XT2, XT3 and XT4 up to 250A & T4, T5 and T6 up to 1000A & T7 and T8 up to 3200A, The ultimate short-circuit breaking capacity (Icu) at 415V ranges from 18kA to 200kA, or up to 100kA for 690V. The following ranges are available:- Circuit-breakers for AC and DC power distribution & Circuit-breakers for zone selectivity & Circuit-breakers for motor protection & Circuit-breakers for application up to 1150V AC and 1500V DC & Switch-disconnectors. Tmax circuit-breakers can be equipped with thermomagnetic, magnetic only or electronic trip units; all of which are interchangeable. Since assembly instructions are simple, trip units can quickly and easily be replaced; even in the field. All this makes the circuit-breakers very easy to operate with considerable savings due to rationalized stock management, All Tmax circuit breakers can be enhanced with a vast range of standardized accessories. This convenience not only cuts down on inventory, but creates an extremely flexible and easily managed solution.
