Why Choose the ABB E4.2S/E10 4000 Ekip Dip LSIG 3p WMP?
The ABB E4.2S/E10 4000 Ekip Dip LSIG 3p WMP, order code 1SDA121100R1, is a SACE Emax 2 air circuit breaker engineered for high-current low-voltage power distribution. Built on the E4.2S/E10 platform, this configuration combines a rated current of 4000 A with three-pole construction and ABB's Ekip Dip electronic trip unit.
The integrated Ekip Dip LSIG trip unit provides long-time, short-time, instantaneous and earth-fault protection functions. This combination supports comprehensive protection of high-current feeders and distribution systems against overloads, delayed and instantaneous short circuits, and earth faults.
The 1SDA121100R1 is supplied as a withdrawable moving part (WMP), allowing the breaker moving portion to be used with the appropriate Emax 2 fixed part. This withdrawable architecture supports inspection, maintenance and replacement strategies in switchboards where serviceability and continuity are important design considerations.
Key Advantages
- High 4000 A rated current for demanding power-distribution applications.
- Ekip Dip LSIG electronic protection for comprehensive fault management.
- Long-time protection for overload conditions.
- Short-time and instantaneous protection for short-circuit conditions.
- Earth-fault protection integrated into the LSIG trip-unit configuration.
- Three-pole construction for three-phase distribution systems.
- Withdrawable moving part design supports maintainable switchboard architectures.
- Part of ABB's established SACE Emax 2 air circuit-breaker platform.

- G: earth-fault protection.
- WMP: withdrawable moving-part configuration.
- Designed for integration with the appropriate Emax 2 fixed part and switchboard system.
LSIG Electronic Protection for High-Current Distribution
The Ekip Dip LSIG trip unit gives the 1SDA121100R1 a coordinated set of electronic protection functions for high-current distribution systems. Long-time protection responds to sustained overloads, while short-time and instantaneous functions address different short-circuit conditions. The additional earth-fault function provides protection against ground-fault currents where required by the system design.
As a withdrawable moving part, the E4.2S/E10 breaker is designed to operate with its corresponding fixed part rather than as a standalone fixed breaker. This architecture can simplify maintenance and breaker replacement while providing the isolation and service flexibility commonly required in critical industrial and commercial switchboards.
Typical Applications
- High-current low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical distribution.
- Main incoming and bus-coupler circuit-breaker applications.
- High-capacity feeder protection.
- Systems requiring LSIG electronic protection.
- Withdrawable switchgear requiring a 4000 A Emax 2 moving part.
