Why Choose the ABB Ekip Touch LSI 100A XT4 3P Trip Unit?
The ABB Ekip Touch LSI In=100A XT4 3P 1SDA100279R1 is an advanced electronic trip unit designed for three-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 100 A, it provides configurable electronic protection for low-voltage AC distribution systems using a compatible XT4 breaking part.
The Ekip Touch LSI release provides long-time, short-time and instantaneous protection functions, covering overload and short-circuit conditions. Its advanced electronic architecture and user interface support accurate protection adjustment, while the Ekip Touch platform is prepared for expanded measurement, communication and digital functionality within compatible ABB systems.
Designed specifically for the ABB XT4 three-pole platform, the 1SDA100279R1 has a nominal current of 100 A and an adjustable overload protection range extending from approximately 0.4 to 1 × In. The trip unit must be combined with a compatible three-pole XT4 breaking part to form a complete moulded case circuit breaker assembly.
Key Advantages
- Advanced ABB Ekip Touch electronic trip unit for the Tmax XT4 platform.
- 100 A nominal current for compatible XT4 circuit-breaker assemblies.
- Three-pole configuration for three-phase AC distribution systems.
- LSI protection functions for overload and short-circuit protection.
- Adjustable electronic protection enables accurate coordination with electrical loads.
- Prepared for expanded measurement and communication functionality.
- Designed for combination with compatible ABB XT4 breaking parts.
Key Features
- ABB SACE Tmax XT series.
- Ekip Touch LSI electronic release.
- 100 A nominal current.
- Three-pole configuration.
- Long-time (L) protection against overload conditions.
- Short-time (S) protection against short-circuit conditions.
- Instantaneous (I) protection against severe short-circuit currents.
- Overload protection adjustment from approximately 0.4 to 1 × In.
- Designed for compatible XT4 moulded case circuit breakers.
Advanced Electronic Protection for ABB XT4 Circuit Breakers
The ABB Ekip Touch LSI monitors current through the circuit breaker and applies electronically controlled protection according to the configured thresholds and timing characteristics. Long-time protection responds to sustained overloads, short-time protection enables coordinated response to short circuits, and instantaneous protection provides rapid tripping during severe fault conditions.
As a modular protection release, the 1SDA100279R1 is intended to be paired with a compatible three-pole ABB XT4 breaking part rather than used as a standalone circuit breaker. This modular approach allows the required breaking performance and electronic protection characteristics to be selected for the electrical distribution application.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution switchboards.
- Commercial electrical distribution systems.
- Manufacturing and process installations.
- Machinery power distribution.
- Three-phase AC feeder protection.
- Compatible ABB XT4 moulded case circuit-breaker assemblies.
