This unit is configured as a fixed 3-pole breaker with front terminals, fitted with a TMA adjustable thermomagnetic release set at In=320A (R320), providing both overload protection (I1 adjustable 224–320A) and short-circuit protection (I3 adjustable 1600–3200A). With a rated insulation voltage of 1000V, impulse withstand of 8kV, and ultimate breaking capacity of 85kA at 230V and 50kA at 400–415V, this breaker is suited to high-demand low voltage distribution systems. Manufactured in Italy in week 29 of 2018, order code 1SDA054440R1, and certified to IEC 60947-2, CE, EAC, and GOST standards, it is fully compliant for international deployment. Industrial procurement teams across the USA source ABB Tmax T5S breakers for main distribution boards, feeder protection, and MCC panels. Electrical contractors and switchgear builders in the UAE specify T5S 400 units for LV distribution and power protection systems.
