Why Choose the ABB Ekip Touch LSIG 100A XT4 4P Trip Unit?
The ABB Ekip Touch LSIG In=100A XT4 4P 1SDA100321R1 is an advanced electronic trip unit designed for four-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 100 A, it provides comprehensive electronic protection for low-voltage AC power-distribution systems when combined with a compatible XT4 four-pole breaking part.
The Ekip Touch LSIG release provides long-time, short-time, instantaneous and ground-fault protection functions. This combination protects electrical installations against sustained overloads, short circuits and earth faults, while adjustable electronic settings enable the protection characteristics to be coordinated with the requirements of the distribution system.
Designed specifically for the ABB XT4 four-pole platform, the 1SDA100321R1 has a nominal current of 100 A. The Ekip Touch platform supports adjustable overload and short-circuit protection and is prepared for measurement, communication and digital functionality, making it suitable for modern industrial and commercial power-distribution applications.
Key Advantages
- Advanced ABB Ekip Touch electronic trip unit for the Tmax XT4 platform.
- 100 A nominal current for compatible XT4 circuit-breaker assemblies.
- Four-pole configuration for three-phase four-wire distribution systems.
- LSIG protection covering overload, short-circuit and ground-fault conditions.
- Adjustable overload protection over a 0.4–1 × In range.
- Adjustable short-circuit protection over a 1–10 × In range with time-delay capability.
- Prepared for measurement and communication functionality.
- Designed for combination with compatible ABB XT4 four-pole breaking parts.
Key Features
- ABB SACE Tmax XT series.
- Ekip Touch LSIG electronic release.
- 100 A rated current.
- Four-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.

- Adjustable electronic protection characteristics for system coordination.
- Prepared for measurement, communication and digital functionality.
Advanced LSIG Protection for ABB XT4 Circuit Breakers
The ABB Ekip Touch LSIG 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 overloads, short-time and instantaneous functions protect against short-circuit currents, and the ground-fault function provides additional protection against earth-fault conditions.
As a modular protection release, the 1SDA100321R1 is designed to be combined with a compatible four-pole ABB XT4 breaking part rather than used as a standalone circuit breaker. This modular approach allows breaking performance and electronic protection characteristics to be selected according to the requirements 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.
- Installations requiring ground-fault protection.
- Compatible ABB XT4 moulded case circuit-breaker assemblies.
