1SDA100361R1

The ABB 1SDA100361R1 is a Tmax XT5N 400 molded-case circuit breaker (MCCB) designed for reliable protection and switching in low-voltage electrical distribution systems. It is a 3-pole, fixed-version breaker with front terminals, equipped with an Ekip Dip LSIG electronic trip unit rated at 320 A. The Ekip Dip LSIG release provides four key protection functions: L (long-time) for overload protection, S (short-time) for time-delayed short-circuit protection, I (instantaneous) for rapid short-circuit protection, and G (ground fault) for earth-fault protection. This makes the breaker suitable for comprehensive protection of feeders and distribution circuits.
