1SDA100205R1 ABB XT4S 250 Ekip Dip LSI 250 A 3-Pole MCCB

Why Choose the ABB 1SDA100205R1 XT4S 250 Circuit Breaker?

The ABB 1SDA100205R1 is a SACE Tmax XT4S 250 moulded case circuit breaker designed for high-performance protection of low-voltage AC power distribution systems. Part of the ABB SACE Tmax XT range, this complete three-pole breaker combines the compact XT4 platform with an Ekip Dip LSI electronic trip unit rated at 250 A.

The Ekip Dip LSI release provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. Its long-time protection can be set across 100–250 A, while the short-time and instantaneous thresholds offer adjustment from 1–10 × In, supporting accurate circuit protection and coordination within industrial and commercial distribution networks.

The XT4S configuration provides an ultimate and service short-circuit breaking capacity of 50 kA at 415 V AC. The 3p F F designation identifies a three-pole, fixed circuit breaker with front terminals, while its operating voltage of up to 690 V AC makes the 1SDA100205R1 suitable for a broad range of demanding low-voltage distribution applications.

High-Performance Electronic MCCB Protection

Moulded case circuit breakers protect electrical distribution circuits against overload and short-circuit conditions while also providing circuit isolation. The ABB SACE Tmax XT4 platform combines compact dimensions with configurable electronic protection, providing dependable interruption performance for modern industrial, commercial and infrastructure power distribution systems.

The Ekip Dip LSI release provides long-time protection against sustained overloads, short-time protection for coordinated response to short-circuit conditions and instantaneous protection against severe fault currents. Combined with the XT4S breaking-capacity class and 50 kA capability at 415 V AC, the 1SDA100205R1 is particularly suited to 250 A distribution circuits where higher prospective fault currents and selective protection are important considerations.

Typical Applications

• Industrial low-voltage distribution boards.
• Commercial electrical switchboards.
• Three-phase feeder circuit protection.
• Main and sub-distribution panels.
• Manufacturing and process-industry electrical systems.
• Infrastructure and building-services power distribution.
