1SDA072509R1 ABB E4.2S 3200 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2S 3200 Ekip Hi-Touch LSIG 3p WMP Air Circuit Breaker?

The ABB E4.2S 3200 Ekip Hi-Touch LSIG 3p WMP, order code 1SDA072509R1, is a high-performance SACE Emax 2 air circuit breaker moving part designed for protection, control and energy management in demanding low-voltage electrical 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 Hi-Touch LSIG electronic trip unit.

The Ekip Hi-Touch LSIG release provides comprehensive protection against overloads, short circuits, instantaneous faults and earth faults, making the breaker suitable for critical industrial and commercial power distribution applications. The Emax 2 platform also supports advanced measurement, diagnostics, connectivity and energy-management functions, helping operators monitor and optimise modern electrical installations.

With an ultimate short-circuit breaking capacity of 85 kA at 415 V AC and 66 kA at 690 V AC, the E4.2S provides robust fault protection for high-current distribution systems. This WMP configuration is the withdrawable moving part of the circuit breaker and is supplied with four auxiliary contacts and indication of the breaker open/closed position, while the compatible fixed part is ordered separately.
