1SDA100758R1 ABB XT6S 800 Ekip Dip LSIG 4-Pole Circuit Breaker

Why Choose the ABB XT6S 800 Ekip Dip LSIG 1SDA100758R1 Circuit Breaker?

The ABB 1SDA100758R1 is a high-performance four-pole moulded case circuit breaker (MCCB) designed for comprehensive protection and isolation in demanding industrial and commercial low-voltage power distribution systems. Part of the ABB SACE Tmax XT series, this XT6S 800 model combines fixed installation, front terminals and an Ekip Dip LSIG solid-state electronic trip unit.

Rated at 800 A, the XT6S is engineered for high-current distribution applications requiring advanced electronic protection. Its Ekip Dip LSIG trip unit provides long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection functions, helping safeguard cables, switchboards and connected electrical equipment against a broad range of electrical faults.

The XT6S interruption performance level provides a rated ultimate short-circuit breaking capacity of 50 kA at 415 V AC and 22 kA at 690 V AC. Its four-pole construction, fixed installation format and front terminals make the 1SDA100758R1 particularly suitable for high-current three-phase distribution systems requiring neutral switching and comprehensive LSIG protection.

Comprehensive LSIG Protection for Power Distribution

Moulded case circuit breakers such as the ABB XT6S protect electrical distribution systems against abnormal current conditions while also providing circuit switching and isolation. The Ekip Dip electronic release monitors current and operates the breaker according to configured protection thresholds, helping protect conductors, switchgear and connected electrical equipment.

The LSIG protection configuration makes the 1SDA100758R1 particularly suitable for distribution systems where comprehensive protection and selective coordination are important. Long-time protection responds to sustained overloads, short-time and instantaneous functions address short-circuit currents, while the ground-fault function provides additional protection against earth-fault conditions.

Typical Applications

• Industrial low-voltage switchboards and distribution panels.
• Main incoming and high-current feeder circuit protection.
• Commercial building electrical distribution systems.
• Manufacturing and process plant power distribution.
• Transformer, generator and installation protection.
• Four-pole three-phase systems requiring neutral switching and LSIG protection.
