1SDA100317R1 ABB Ekip Dip LSIG In=250A XT4 4p

Why Choose the ABB Ekip Dip LSIG In=250A XT4 4p 1SDA100317R1?

The ABB 1SDA100317R1 is an Ekip Dip LSIG electronic trip unit designed for compatible four-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 250 A, it provides comprehensive solid-state protection for low-voltage AC electrical distribution systems requiring accurate overload, short-circuit and ground-fault protection.

Its LSIG protection functions combine long-time protection against sustained overloads, short-time protection for coordinated short-circuit response, instantaneous protection for severe short circuits and ground-fault protection for earth-fault conditions. This combination makes the release suitable for demanding distribution systems where comprehensive electronic protection and coordination are required.

The 1SDA100317R1 is specifically configured for the ABB Tmax XT4 four-pole platform. It is supplied as a separate electronic release rather than a complete moulded case circuit breaker, allowing it to be combined with a compatible XT4 breaking part selected according to the required short-circuit breaking performance and installation configuration.

Key Advantages

• ABB Ekip Dip electronic protection for compatible Tmax XT4 moulded case circuit breakers.
• 250 A rated current for substantial low-voltage distribution loads.
• LSIG protection functions provide long-time, short-time, instantaneous and ground-fault protection.
• Four-pole configuration supports compatible three-phase and neutral circuit-breaker assemblies.
• Solid-state electronic release provides dependable protection for AC electrical distribution systems.
• Modular construction allows pairing with a compatible ABB XT4 breaking part selected for the required short-circuit performance.

Advanced LSIG Protection for Electrical Distribution

The Ekip Dip LSIG release combines four complementary protection functions within a single electronic trip unit. Long-time protection responds to sustained overload conditions, short-time protection enables coordinated response to short-circuit faults, instantaneous protection provides rapid tripping during severe short circuits, and ground-fault protection detects potentially damaging earth-fault conditions.

Because the 1SDA100317R1 is supplied as a separate electronic release, it can be combined with a compatible four-pole XT4 breaking part to form the required circuit-breaker assembly. This modular ABB Tmax XT architecture allows the 250 A LSIG protection unit to be matched with the appropriate breaking part according to the required short-circuit performance and installation requirements.

Typical Applications

• Industrial low-voltage switchboards.
• Main and sub-distribution panels.
• Three-phase and neutral electrical distribution systems.
• Commercial and infrastructure electrical installations.
• Manufacturing and process industry power systems.
• Feeder circuits requiring coordinated overload, short-circuit and ground-fault protection.
• ABB Tmax XT4 circuit-breaker assemblies requiring a 250 A LSIG electronic trip unit.
