Why Choose the ABB XT5S 400 Ekip Dip LSIG 1SDA100474R1 Circuit Breaker?

The ABB 1SDA100474R1 is a high-performance SACE Tmax XT5S moulded-case circuit breaker (MCCB) designed for dependable protection and switching in low-voltage AC electrical distribution systems. This fixed four-pole circuit breaker features front terminals and an advanced Ekip Dip LSIG solid-state electronic trip unit, providing comprehensive protection against overload, short-circuit and ground-fault conditions.

As part of the ABB SACE Tmax XT series, the XT5S 400 combines compact construction with configurable electronic protection. Its Ekip Dip LSIG release provides Long-time (L), Short-time (S), Instantaneous (I) and Ground-fault (G) protection functions, supporting effective coordination of cables, distribution equipment and connected loads in demanding industrial and commercial installations.

The 1SDA100474R1 has a 400 A rated current and a four-pole configuration. The XT5S breaking-capacity class provides an ultimate short-circuit breaking capacity of 50 kA at 380–415 V AC, while its fixed mounting arrangement and front terminals support straightforward integration into switchboards and power distribution assemblies.
