Abb sace tmax xt ml circuit breakers are the most advanced and complete solution for ensu ring service continuity. with built in communication modules, integrated software functions and excellent selectivity com binations, these circuit breakers take electrical system reliability to new levels. Tmax t8 is able to interrupt the following short circuit currents: 125 ka@480 v and 100 ka@600 v. the tmax t8 size has both circuit breakers and molded case switches (mcs). the following tables show the main characteristics of these ranges. Up to an altitude of 6600 ft the tmax circuit breakers do not undergo any changes in their rated perfor mance. above this altitude, the atmospheric properties are altered in terms of composition, dielectric resistance, cooling capacity and pressure, requiring the circuit breaker performance to be derated per the table below. This circuit breaker has been designed to operate with voltage and current values within the rating plate limits: do not install in systems that operate at values exceeding these rated limits.
