Why Choose the ABB Ekip Dip LIG In=25A XT2 3P Trip Unit?
The ABB Ekip Dip LIG In=25A XT2 3P, order code 1SDA100128R1, is a three-pole electronic trip unit designed for compatible ABB SACE Tmax XT2 moulded case circuit breakers. Rated at 25 A, it provides electronic protection for low-voltage AC power distribution applications while supporting the modular configuration of the XT2 circuit-breaker platform.
The Ekip Dip LIG release provides long-time (L), instantaneous (I) and earth-fault (G) protection. These functions protect against sustained overloads, severe short-circuit currents and earth-fault conditions, providing a comprehensive protection package for feeders and distribution circuits where dedicated ground-fault protection is required.
The 1SDA100128R1 is supplied as a loose/configurable trip unit rather than a complete circuit breaker. It is intended to be combined with a compatible XT2 breaking part, allowing the circuit-breaker breaking capacity and installation arrangement to be selected separately while retaining the specified 25 A Ekip Dip LIG protection.
Key Advantages
- 25 A electronic trip unit for compatible ABB SACE Tmax XT2 circuit breakers.
- LIG protection covers overload, instantaneous short-circuit and earth-fault conditions.
- Electronic protection technology provides configurable protection functionality for low-voltage distribution.
- Integrated G earth-fault function for circuits requiring dedicated earth-fault protection.
- Three-pole execution for compatible XT2 three-pole breaking parts.
- AC application for power-distribution circuit protection.
- Modular design allows the trip unit and XT2 breaking part to be selected separately.

- 25 A rated current.
- Ekip Dip electronic release.
- LIG electronic protection functions.
- L – Long-time overload protection.
- I – Instantaneous short-circuit protection.
- G – Earth-fault protection.
- Three-pole configuration.
- AC current type.
- Loose/configurable execution for modular XT2 circuit-breaker assembly.
- Designed for use with compatible ABB Tmax XT2 power-distribution circuit breakers.
Electronic LIG Protection for ABB Tmax XT2
The Ekip Dip LIG release combines three complementary electronic protection functions. Long-time protection responds to sustained overload currents, instantaneous protection provides rapid operation during severe short-circuit faults, and the G function provides dedicated earth-fault protection. Unlike LSI and LSIG releases, the LIG configuration does not include a short-time S protection function.
The ABB 1SDA100128R1 is the 25 A three-pole electronic trip-unit component rather than a complete MCCB. ABB's modular Tmax XT2 architecture enables the trip unit to be paired with an appropriate XT2 breaking part, allowing the final circuit-breaker configuration and breaking performance to be selected according to the requirements of the electrical installation.
Typical Applications
- ABB SACE Tmax XT2 circuit-breaker configurations.
- Industrial low-voltage power distribution.
- Commercial building electrical distribution.
- Three-phase feeder protection.
- Circuits requiring integrated earth-fault protection.
- Industrial switchboards and distribution panels.
- OEM electrical distribution assemblies.
