Why Choose the ABB 1SDA100703R1 Ekip G Touch LSIG Trip Unit?
The ABB 1SDA100703R1 is an advanced Ekip G Touch LSIG electronic trip unit designed specifically for generator protection with compatible ABB Tmax XT5 moulded-case circuit breakers. Rated at 250 A and configured for 4-pole AC applications, it provides comprehensive electronic protection for generators and generator-fed low-voltage distribution systems.
As part of the ABB SACE Tmax XT range, the Ekip G Touch platform combines generator-focused protection with advanced measurement, communication and digital functionality. Its LSIG protection functions provide long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection, helping protect generating equipment, feeders and associated electrical infrastructure.
With a rated current of 250 A, the 1SDA100703R1 is designed to be combined with a compatible 4-pole ABB Tmax XT5 breaking unit. Its overload protection can be adjusted over a 0.4–1 × In range and short-circuit protection over a 1–10 × In range, with time-delay capability supporting selective and coordinated generator protection schemes.

Advanced Electronic Protection for Generators
Generator protection requires careful coordination because generator fault-current and overload characteristics differ from those of conventional utility-fed distribution systems. The ABB Ekip G platform is specifically intended for generator applications, providing configurable electronic protection that can be matched to the operating characteristics of generating equipment and associated electrical circuits.
The Ekip G Touch LSIG release combines long-time overload, short-time short-circuit, instantaneous short-circuit and ground-fault protection. When paired with the appropriate Tmax XT5 breaking unit, the 1SDA100703R1 provides comprehensive protection for generator feeders and connected equipment while also supporting measurement, communication and digital integration requirements.
Typical Applications
- Industrial generator protection systems.
- Standby and emergency power generators.
- Four-pole three-phase generator circuits.
- Generator-fed low-voltage switchboards.
- Data centre and critical-power generating systems.
- Commercial and infrastructure standby power installations.
- Industrial plants with on-site power generation.
- ABB Tmax XT5 installations requiring advanced LSIG generator protection.
