The ABB 1SDA100180R1 is a Tmax XT4N 250 molded-case circuit breaker (MCCB) designed for reliable protection and switching of low-voltage electrical distribution systems. The breaker features a 3-pole fixed construction with front terminals and is equipped with an Ekip Dip LSIG solid-state electronic release rated at 250 A. The Ekip Dip LSIG trip unit provides four primary protection functions: long-time (L) overload protection, short-time (S) short-circuit protection, instantaneous (I) short-circuit protection, and ground-fault (G) protection. This makes the device suitable for comprehensive protection of feeders and distribution circuits.
