ABB SACE Industrial Automation Component

The ABB SACE Tmax T1 is the small-frame member of the classic Tmax T MCCB family. It covers applications up to a 160 A frame with 3-pole or 4-pole constructions, compliant with IEC 60947-2 and typical system voltages up to 690 V AC. Select the proper breaking-capacity code—T1B / T1N / T1S / T1H—to match your available fault current, and choose the TMD thermal-magnetic trip rating that fits your circuit.
The T1 supports fixed or plug-in mounting (kit-dependent), front rotary handles, auxiliary contacts, shunt/undervoltage releases, terminal shrouds, and motor operators, making it easy to integrate in switchboards and control panels. If you’re modernizing, T1 is commonly replaced like-for-like or migrated to the newer Tmax XT1 platform; check dimensions, terminals, and trip selections before swapping.
