1SDA100287R1 ABB Ekip Touch Measuring LSI 250 A XT4 3-Pole Trip Unit

Why Choose the ABB 1SDA100287R1 Ekip Touch Measuring LSI Trip Unit?

The ABB 1SDA100287R1 is an advanced Ekip Touch Measuring LSI electronic trip unit designed for compatible SACE Tmax XT4 moulded-case circuit breakers. Rated at 250 A and configured for 3-pole applications, it combines configurable electronic circuit protection with an intuitive touch interface and integrated electrical measurement capabilities.

As part of the ABB SACE Tmax XT protection platform, the Ekip Touch Measuring release provides LSI protection, comprising long-time overload, short-time selective short-circuit and instantaneous short-circuit functions. Its microprocessor-based architecture enables accurate protection settings while the Measuring version provides enhanced electrical monitoring for modern low-voltage distribution systems.

The 1SDA100287R1 is specifically designed for XT4 3-pole circuit-breaker configurations and has a rated current of 250 A. It is a separate electronic protection release rather than a complete moulded-case circuit breaker, allowing it to be combined with compatible XT4 breaking parts of different short-circuit performance levels according to the requirements of the installation.

Advanced Protection and Measurement for SACE Tmax XT4

The ABB Ekip Touch Measuring platform extends conventional circuit protection by combining configurable electronic trip functions with integrated measurement capabilities. For the 1SDA100287R1, LSI protection provides long-time overload protection together with short-time selective and instantaneous short-circuit protection, enabling the release to support dependable and coordinated protection strategies within low-voltage distribution networks.

The modular design allows this 250 A, 3-pole release to be combined with compatible XT4 breaking parts selected according to the required interruption performance. This means the same Ekip Touch Measuring LSI trip-unit technology can form part of different XT4 circuit-breaker configurations while providing a consistent protection, measurement and user-interface platform.

Typical Applications

• ABB SACE Tmax XT4 circuit-breaker assemblies.
• Industrial low-voltage power distribution.
• Commercial building distribution systems.
• Main and sub-distribution switchboards.
• Manufacturing and process facilities.
• Infrastructure electrical distribution.
• Feeders requiring configurable LSI electronic protection.
• Applications requiring integrated protection and electrical measurement.
