ABB SACE Tmax XT4S 250 is a three-pole molded-case circuit breaker (MCCB) in the XT4S frame, rated for 600 V AC and 250 A. This fixed, front-terminal unit uses the EKIP-LS/I trip unit for thermal-magnetic protection on distribution circuits and motors. The Brazilian variant with part number 1SDA068475R1BR lists a short-circuit current rating (Icu) up to 50 kA at 380 V. Commonly, it protects industrial switchgear and motor control centers where robust overload and short-circuit protection is required.
