Why Choose the ABB Ekip Touch LSI 250A XT4 4P Trip Unit?
The ABB Ekip Touch LSI In=250A XT4 4P 1SDA100320R1 is an advanced electronic trip unit designed for four-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 250 A, it provides configurable electronic protection for low-voltage AC power-distribution systems when combined with a compatible XT4 breaking part.
The Ekip Touch LSI release provides long-time, short-time and instantaneous protection functions. These functions protect electrical installations against sustained overloads and short-circuit conditions, while the Ekip Touch interface provides convenient access to protection settings and operating information.
Designed specifically for the ABB XT4 four-pole platform, the 1SDA100320R1 has a rated current of 250 A and an adjustable long-time protection range from 100–250 A. Its modular construction allows it to be combined with a compatible XT4 breaking part to create a complete moulded case circuit-breaker configuration for industrial and commercial distribution systems.
Key Advantages
- Advanced ABB Ekip Touch electronic trip unit for the Tmax XT4 platform.
- 250 A rated current for compatible XT4 circuit-breaker assemblies.
- Four-pole configuration for three-phase four-wire distribution systems.
- LSI protection functions for overload and short-circuit protection.
- Adjustable long-time protection from 100–250 A.
- Electronic protection provides accurate and repeatable circuit-breaker operation.
- Designed for integration with compatible ABB XT4 breaking parts.

Advanced Electronic LSI Protection for ABB XT4
The ABB Ekip Touch LSI electronically monitors current through a compatible XT4 circuit breaker and applies protection according to configured thresholds and timing characteristics. Long-time protection responds to sustained overload conditions, short-time protection enables coordinated response to short circuits, and instantaneous protection provides rapid interruption of severe fault currents.
As a modular protection release, the 1SDA100320R1 is intended to be combined with a compatible four-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 according to the needs of the electrical distribution system.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution switchboards.
- Commercial building electrical distribution.
- Manufacturing and process installations.
- Machinery power-distribution systems.
- Three-phase four-wire AC distribution networks.
- Feeder and installation protection.
- Compatible ABB XT4 moulded case circuit-breaker assemblies.
