1SDA100112R1 ABB Ekip Touch Measuring LSIG In=40A XT2 3P Electronic Trip Unit

Why Choose the ABB Ekip Touch Measuring LSIG In=40A XT2 3P Trip Unit?

The ABB Ekip Touch Measuring LSIG In=40A XT2 3P, order code 1SDA100112R1, is an advanced solid-state electronic trip unit designed for compatible three-pole ABB SACE Tmax XT2 moulded case circuit breakers. Rated at 40 A, it combines comprehensive electronic circuit protection with integrated measuring functionality for sophisticated low-voltage distribution applications.

The Ekip Touch Measuring LSIG platform provides long-time (L), short-time (S), instantaneous (I) and earth-fault (G) protection. This combination enables protection against sustained overloads, short-circuit conditions requiring selective operation, severe instantaneous faults and earth faults while providing measurement capabilities for improved visibility of the electrical system.

The 1SDA100112R1 is a three-pole XT2 electronic trip unit rather than a complete moulded case circuit breaker. It is designed to be combined with a compatible ABB XT2 breaking part, allowing the required breaking-capacity level and installation configuration to be selected as part of the complete circuit-breaker assembly.

Key Advantages

• 40 A Ekip Touch Measuring electronic trip unit for compatible ABB SACE Tmax XT2 circuit breakers.
• LSIG protection covers overload, short-time short-circuit, instantaneous short-circuit and earth-fault conditions.
• Integrated measuring functionality supports enhanced monitoring of the electrical installation.
• Ekip Touch interface provides an advanced platform for protection configuration and information access.
• Three-pole execution for compatible XT2 three-pole breaking parts.
• Supports coordinated and selective protection strategies in sophisticated distribution systems.
• Modular design allows the trip unit and XT2 breaking part to be selected separately.

• Three-pole execution.
• Solid-state release for AC applications.
• Designed for ABB's modular Tmax XT2 circuit-breaker architecture.

Advanced Ekip Touch Measuring LSIG Protection

The Ekip Touch Measuring LSIG release combines four complementary protection functions. Long-time protection responds to sustained overloads, short-time protection supports selective coordination during short-circuit events, instantaneous protection provides rapid intervention under severe fault conditions, and the G function provides dedicated earth-fault protection. This makes the trip unit suitable for distribution systems requiring comprehensive electronic protection and coordination.

In addition to its protection functions, the Measuring version incorporates electrical measurement capabilities within the Ekip Touch platform. The ABB 1SDA100112R1 is the 40 A three-pole electronic trip-unit component and must be combined with an appropriate XT2 breaking part to form the required complete circuit-breaker configuration.

Typical Applications

• ABB SACE Tmax XT2 circuit-breaker configurations.
• Industrial low-voltage distribution systems.
• Commercial and infrastructure electrical distribution.
• Three-phase feeder protection.
• Circuits requiring integrated earth-fault protection.
• Switchboards requiring electronic LSIG protection and measurement.
• OEM switchboards and electrical distribution assemblies.
