1SDA100589R1 ABB Ekip Dip LSIG 630 A XT5 3-Pole Electronic Trip Unit

Why Choose the ABB Ekip Dip LSIG In=630 XT5 3p 1SDA100589R1 Trip Unit?

The ABB Ekip Dip LSIG In=630 XT5 3p 1SDA100589R1 is a 630 A three-pole solid-state electronic trip unit designed for compatible ABB SACE Tmax XT5 circuit-breaker breaking parts. It forms part of ABB's modular Tmax XT power-distribution protection system and provides comprehensive electronic protection for demanding low-voltage electrical networks.

The Ekip Dip LSIG release provides four principal protection functions: long-time overload (L), short-time short-circuit (S), instantaneous short-circuit (I) and ground-fault protection (G). Long-time protection is adjustable over 0.4–1 × In, while the short-time and instantaneous thresholds provide adjustment over 1–10 × In, allowing protection characteristics to be coordinated with the requirements of the installation.

Rated at 630 A and designed for a three-pole XT5 configuration, the 1SDA100589R1 is supplied as a loose/configurable electronic release rather than as a complete moulded case circuit breaker. It must therefore be combined with a compatible ABB XT5 breaking part, which determines the complete breaker's interruption performance and installation configuration.

Key Advantages

• 630 A electronic trip unit engineered for compatible ABB SACE Tmax XT5 circuit breakers.
• LSIG protection covers overload, delayed short-circuit, instantaneous short-circuit and ground-fault conditions.
• Long-time protection adjustable over 0.4–1 × In.
• Short-time and instantaneous protection adjustable over 1–10 × In.
• Three-pole configuration for compatible three-phase XT5 circuit-breaker assemblies.
• Modular ABB design allows the release to be combined with the appropriate XT5 breaking part for the required interruption performance.

• Loose/configurable construction for combination with a compatible XT5 breaking part.

Comprehensive LSIG Electronic Protection for ABB XT5

Electronic trip units provide greater protection flexibility than conventional fixed protection devices by allowing key operating thresholds to be matched to the characteristics of the electrical system. The Ekip Dip LSIG combines overload and multiple short-circuit protection functions with ground-fault protection, making it particularly suitable for distribution systems where selectivity and coordinated protection are important.

The ABB 1SDA100589R1 is the protection release rather than a complete circuit breaker. ABB's modular XT5 architecture allows the Ekip Dip LSIG unit to be combined with a suitable XT5 breaking part. The breaking part establishes characteristics such as interruption performance and mounting arrangement, while this release provides the 630 A LSIG electronic protection.

Typical Applications

• ABB SACE Tmax XT5 circuit-breaker assemblies.
• Industrial low-voltage power distribution.
• Main and feeder circuit protection.
• Cable and electrical distribution protection.
• Generator and installation protection.
• Commercial and infrastructure switchboards requiring LSIG protection.
