Why Choose the ABB 1SDA100323R1 Ekip Touch LSIG 250A Trip Unit?
The ABB 1SDA100323R1 is an advanced Ekip Touch LSIG electronic trip unit designed for use with four-pole ABB SACE Tmax XT4 moulded-case circuit breakers in AC power distribution applications. Rated at 250 A, this electronic protection release provides configurable protection functions for overload, short-circuit and earth-fault conditions.
As part of the ABB SACE Tmax XT range, the Ekip Touch platform combines sophisticated electronic protection with an intuitive touch interface and flexible configuration capabilities. LSIG protection provides Long-time (L), Short-time (S), Instantaneous (I) and Ground-fault (G) functions, allowing the protection characteristics to be adapted to the requirements of the electrical distribution system.
The 1SDA100323R1 is a four-pole electronic trip unit with a rated current of 250 A and is specifically suitable for the ABB XT4 circuit-breaker platform. Its configurable protection settings, digital architecture and compatibility with ABB's wider Ekip ecosystem make it suitable for demanding commercial and industrial low-voltage distribution systems.

Advanced Protection for Low-Voltage Power Distribution
Electronic trip units continuously monitor current through a circuit breaker and initiate tripping when configured protection thresholds are exceeded. Compared with basic protection releases, the Ekip Touch platform provides greater flexibility for coordinating protection settings across complex low-voltage distribution systems.
The LSIG configuration provides comprehensive protection against overloads, delayed and instantaneous short circuits and earth faults. When combined with a compatible four-pole Tmax XT4 circuit breaker, the 1SDA100323R1 helps protect cables, distribution equipment and downstream electrical installations while supporting selective protection strategies.
Typical Applications
- Industrial low-voltage power distribution systems.
- Commercial electrical distribution boards.
- Switchboards and electrical control panels.
- Protection of feeders and distribution circuits.
- Manufacturing and process installations.
- Infrastructure and building power distribution.
