Hanover, April 13, 2015 – ABB, the leading power and automation technology group, is now offering the Tmax XT family for UL 489 and CSA C22.2 standards.
The Tmax XT UL represents one of the most compact molded case circuit breakers (MCCB) on the market at up to 250 amperes. Carrying also IEC marking, the complete Tmax XT UL line represents a globally recognized product.
The new Tmax XT circuit breakers offer high breaking capacity in up to 37% smaller size. The smaller footprint and extended amperages enable panel builders and manufacturers to save costs while maintaining high performance.
“Expanded breaking capacities and increased performance means that the Tmax XT UL family meets a greater variety of application needs in the most efficient size,” says Alessandro Lo Turco, Global Product Manager for molded case circuit breakers. “For example, Tmax XT4 and XT2 UL now have six breaking capacity options and higher overall performance with 200kA @480V. And Tmax XT1 UL now features increased performance of up to 65kA @480V. In addition to this, UL 489 current limiting version of Tmax XT2 and XT4 at 480 and 600 voltage makes switchboard certification easy’’.
The Tmax XT family is ideal for all types of power distribution, motor and generator protection, thanks to the latest generation trip units:
- Ekip M-LIU for XT2 and XT4 for electronic motor protection with integrated overload and phase loss detection.
- Ekip E-LSIG for XT4, a measuring option for advanced applications.
- Thermal magnetic trip units for DC applications.
The Tmax XT UL also comes with new accessories for faster, easier and more flexible installation options such as push-in, cabled or non-cabled electrical accessories. Additional auxiliary contacts offer more signaling versatility and options for heavy duty applications. The mechanical accessory line has been expanded to include additional options for power termination and operating mechanisms.
