1SDA100498R1 ABB XT5H 400 Ekip Dip LSIG 400 A 3-Pole Circuit Breaker

Why Choose the ABB XT5H 400 Ekip Dip LSIG 1SDA100498R1 Circuit Breaker?

The ABB XT5H 400 Ekip Dip LSIG 1SDA100498R1 is a high-performance 400 A moulded case circuit breaker (MCCB) designed for dependable protection and switching in demanding low-voltage electrical distribution systems. Part of the ABB SACE Tmax XT series, this three-pole breaker combines the XT5 400 frame with an electronic Ekip Dip LSIG trip unit and H-class short-circuit performance.

The XT5H is engineered for transformer, generator and installation protection where accurate electronic protection and high fault-interruption capability are required. Its Ekip Dip LSIG solid-state release provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection, giving electrical designers a comprehensive set of protection functions for coordinated distribution systems.

With a rated current of 400 A, a three-pole fixed configuration with front terminals and an ultimate short-circuit breaking capacity of 70 kA at 415 V AC, the 1SDA100498R1 is well suited to industrial switchboards and high-fault-level distribution networks. Its adjustable protection includes a 160–400 A long-time range, short-time and instantaneous settings from 1–10 × In, and ground-fault adjustment from 0.2–1 × In.

Comprehensive Protection for High-Fault-Level Distribution Systems

Moulded case circuit breakers such as the ABB XT5H provide dependable protection against overload, short-circuit and earth-fault conditions while also serving as switching and isolation devices within low-voltage installations. Electronic trip technology allows protection characteristics to be coordinated with conductors, transformers, generators and downstream protective devices, supporting selective and reliable electrical distribution.

The Ekip Dip LSIG release provides all four principal electronic protection functions—long-time, short-time, instantaneous and ground fault—within the compact XT5 platform. Combined with the XT5H's 70 kA breaking capacity at 415 V AC, this makes the 1SDA100498R1 particularly suitable for installations with high prospective fault currents and demanding protection-coordination requirements.

Typical Applications

• Industrial low-voltage distribution boards.
• Main and high-current feeder protection.
• Transformer protection and distribution systems.
• Generator protection and power distribution.
• Manufacturing and process facilities.
• Commercial and infrastructure switchboards with high prospective fault currents.
