Why Choose the ABB E1.2B 1600 Ekip G Touch LSIG 4p WMP Air Circuit Breaker?
The ABB E1.2B 1600 Ekip G Touch LSIG 4p WMP, order code 1SDA072847R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for generator protection and demanding low-voltage power distribution systems. Part of the ABB SACE Emax 2 E1.2 series, it combines a 1600 A rated current with an Ekip G Touch LSIG solid-state electronic trip unit for advanced overload, selective short-circuit, instantaneous and earth-fault protection.
The Ekip G Touch LSIG trip unit is designed for applications where generator and distribution protection require advanced electronic control. It provides long-time overload, short-time delayed short-circuit, instantaneous short-circuit and earth-fault protection, with configurable settings that support selective coordination and dependable protection across generator-fed and conventional low-voltage networks.
The E1.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 400/415 V AC and 42 kA at 690 V AC, together with a rated short-time withstand current of 42 kA for 1 s. Its withdrawable four-pole construction supports maintainable switchboard designs where rapid inspection, servicing and replacement of the breaker moving part are important.

Advanced Generator and Distribution Protection
The ABB Ekip G Touch platform extends Emax 2 electronic protection capabilities for generator applications and complex distribution systems. Its LSIG protection functions provide coordinated response to sustained overloads, selective short circuits, high-magnitude instantaneous faults and earth faults, helping protect generators, conductors, switchgear and connected loads under demanding operating conditions.
The withdrawable E1.2B construction is particularly suitable for generator switchboards, industrial distribution panels and other installations where serviceability and continuity are important. The moving breaker can be withdrawn from its corresponding fixed part for inspection or maintenance, while the electronic trip unit provides flexible protection configuration for the requirements of the electrical network.
Typical Applications
- Generator protection and generator switchboards.
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure power distribution.
- Manufacturing and process facilities.
- Emergency and standby generation systems.
- Critical power distribution installations.
- Withdrawable switchgear requiring advanced LSIG protection.
