Why Choose the ABB Ekip Hi-Touch LSIG 250A XT4 4P Trip Unit?
The ABB Ekip Hi-Touch LSIG In=250A XT4 4P 1SDA100335R1 is an advanced solid-state electronic trip unit designed for four-pole ABB SACE Tmax XT4 moulded case circuit breakers. Rated at 250 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 Hi-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, making the trip unit suitable for demanding industrial and commercial power-distribution applications.
Designed specifically for the ABB XT4 four-pole platform, the 1SDA100335R1 has a rated current of 250 A. Its overload protection is adjustable over a 0.4–1 × In range and short-circuit protection over a 1–10 × In range, with time-delay capability. The advanced Hi-Touch platform is also prepared for measurement, communication and digital functionality.
Key Advantages
- Advanced ABB Ekip Hi-Touch electronic trip unit for the Tmax XT4 platform.
- 250 A rated current for compatible XT4 circuit-breaker assemblies.
- Four-pole configuration for four-pole power-distribution applications.

Advanced LSIG Protection for ABB XT4 Circuit Breakers
The ABB Ekip Hi-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 1SDA100335R1 is designed to be combined with a compatible four-pole ABB XT4 breaking part rather than used as a standalone circuit breaker. Its advanced Hi-Touch architecture is also prepared for measurement, communication and digital functionality, providing a flexible protection platform for modern electrical distribution systems.

- Main and sub-distribution switchboards.
- Commercial building electrical distribution.
- Manufacturing and process installations.
- Machinery power-distribution systems.
- Four-pole AC power-distribution networks.
- Installations requiring ground-fault protection.
- Compatible ABB XT4 moulded case circuit-breaker assemblies.
