Why Choose the ABB 1SDA100536R1 XT5H 400 Circuit Breaker?
The ABB 1SDA100536R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for transformer, generator and low-voltage installation protection. Part of the ABB SACE Tmax XT series, this XT5H 400 breaker combines high short-circuit interruption capability with an Ekip Dip LSIG solid-state electronic trip unit for comprehensive circuit protection.
The circuit breaker has a 400 A rated current within the XT5 400 A frame. Its Ekip Dip LSIG electronic trip unit provides long-time overload protection, short-time short-circuit protection, instantaneous short-circuit protection and ground-fault protection, delivering a versatile protection package for demanding electrical distribution systems.
The XT5H configuration provides a high short-circuit performance level of 70 kA. Its four-pole fixed construction, front terminal connections and electronic protection make the 1SDA100536R1 particularly suitable for industrial switchboards, generator panels, transformer circuits and three-phase four-wire distribution systems.
