ABB Tmax XT1 and XT3 MCCBs are fixed three-pole molded case circuit breakers designed for power distribution with thermomagnetic TMD/TMF release protection. Engineered for 160–1600A applications, these breakers provide precise overload and short-circuit protection for industrial LV systems. Key features include front terminals, compact frame size, high breaking capacity, and reliable isolation performance.

TMF - Fixed thermal and fixed magnetic for power distribution

TMD - Adjustable thermal (70-100%of In) and fixed magnetic (10 x In) for power distribution
Terminal Type: Front Terminals
Mounting: Fixed Type
Standards Compliance: IEC 60947-2 

ABB Tmax XT2, XT4, XT5 and XT6 3-pole molded case circuit breakers are engineered for industrial power distribution with thermomagnetic TMD/TMA release protection. Designed for 160A to 1600A applications, these MCCBs provide precise overload and short-circuit protection in low-voltage systems. Featuring fixed execution, front terminals, high breaking capacity and compact frame design, they ensure dependable isolation for MCC panels, distribution boards and heavy-duty infrastructure installations.

TMD - Adjustable thermal (70-100%of In) and fixed magnetic (10 x In) for power distribution

TMA - Adjustable thermal (70-100% of In) and adjustable magnetic (5-10 of In) for power distribution
Terminal Type: Front Terminals
Mounting: Fixed Type
Standards Compliance: IEC 60947-2
