ABB Tmax XT2S 160 Molded Case Circuit Breaker
The XT2S 160 TMA 100-1000 is a four-pole molded case circuit breaker (MCCB) from the ABB SACE Tmax XT family. It features a TMA thermomagnetic trip unit set to 100 A continuous current with an adjustable magnetic threshold of 500–1000 A, providing both overload and short-circuit protection for distribution, motor and feeder circuits.
The frame current (Iu) is 160 A and the breaking capacity reaches 50 kA at 400 V (85 kA at 230 V), making the XT2S suitable for demanding industrial and commercial switchboards in a compact footprint. Rated insulation voltage is 1000 V with 8 kV impulse withstand.
The fixed four-pole breaker is built and tested according to IEC 60947-2 and integrates with the full Tmax XT accessory range (auxiliary contacts, shunt releases, motor operators and interlocks) for panel builders and system integrators.
