Why Choose the ABB E4.2S 3200 Ekip G Hi-Touch LSIG 3p WMP Air Circuit Breaker?
The ABB E4.2S 3200 Ekip G Hi-Touch LSIG 3p WMP, order code 1SDA072510R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for generator protection and demanding low-voltage power distribution systems. As part of the advanced ABB SACE Emax 2 E4.2 series, this three-pole withdrawable breaker combines a 3200 A rated current with the sophisticated Ekip G Hi-Touch LSIG electronic trip unit.
The Ekip G Hi-Touch trip unit is specifically suited to applications requiring advanced generator and distribution protection, providing LSIG functions for overload, short-time short-circuit, instantaneous short-circuit and earth-fault protection. The Emax 2 platform also supports extensive measurement, diagnostics, connectivity and energy-management capabilities for integration into modern electrical networks.
With an ultimate short-circuit breaking capacity of 85 kA at 415 V AC and 66 kA at 690 V AC, the E4.2S delivers robust fault interruption for high-current installations. This WMP configuration is the withdrawable moving part and is supplied with four auxiliary contacts, allowing it to be integrated with a compatible Emax 2 E4.2 fixed part for flexible switchboard installation and maintenance.
