Why Choose the ABB E1.2B 1600 Ekip Hi-Touch LSI 4p WMP Air Circuit Breaker?
The ABB E1.2B 1600 Ekip Hi-Touch LSI 4p WMP, order code 1SDA072848R1, is a high-performance four-pole withdrawable air circuit breaker moving part designed for protection, switching and advanced power management in demanding low-voltage distribution systems. Part of the ABB SACE Emax 2 E1.2 series, it combines a 1600 A rated current with an Ekip Hi-Touch LSI solid-state electronic trip unit for sophisticated overload and short-circuit protection.
The Ekip Hi-Touch LSI release provides long-time overload, short-time delayed short-circuit and instantaneous short-circuit protection. Its advanced electronic platform supports precise protection configuration, measurement and supervision, while the short-time function enables selective coordination between protective devices across complex industrial and commercial distribution networks.
The E1.2B performance level provides an ultimate short-circuit breaking capacity of 42 kA at 400/415 V AC, together with a rated short-time withstand current of 42 kA for 1 s. Its withdrawable four-pole construction enables the moving breaker to be separated from the corresponding fixed part for inspection and servicing, supporting maintainable switchboard installations.
Key Advantages
- 1600 A rated current for high-current low-voltage distribution systems.
- Four-pole configuration for comprehensive switching and circuit protection.

Advanced Protection and Power Management
The ABB Ekip Hi-Touch platform is designed for installations requiring sophisticated electronic protection, measurement and power-management capabilities. In this LSI configuration, long-time protection responds to sustained overloads, short-time protection supports selective coordination during fault conditions, and instantaneous protection provides rapid interruption of severe short circuits.
The withdrawable E1.2B construction is particularly useful in switchboards where maintainability, operational flexibility and continuity of service are important. The breaker moving part can be separated from its corresponding fixed part for inspection or servicing, while four auxiliary contacts and open/closed position indication support integration with switchboard signalling and control systems.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial building electrical distribution.
- Manufacturing and process facilities.
- Transformer and generator distribution systems.
- Infrastructure and utility installations.
- Critical power distribution systems.
- Withdrawable switchgear requiring advanced selective LSI protection.
