1SDA073340R1 ABB E6.2H/f 5000 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker

Why Choose the ABB E6.2H/f 5000 Ekip G Hi-Touch LSIG 4p WMP Air Circuit Breaker?

The ABB E6.2H/f 5000 Ekip G Hi-Touch LSIG 4p WMP, order code 1SDA073340R1, is a high-performance Emax 2 air circuit breaker (ACB) designed for generator protection and demanding high-current low-voltage electrical distribution systems. As part of the advanced ABB Emax 2 series, this four-pole breaker combines a 5000 A rated uninterrupted current with the Ekip G Hi-Touch LSIG electronic trip unit for comprehensive protection, monitoring and control.

The Ekip G Hi-Touch LSIG release provides long-time overload (L), selective short-circuit (S), instantaneous short-circuit (I) and earth-fault (G) protection, together with the advanced functionality of ABB's Hi-Touch platform. The generator-oriented Ekip G configuration makes this breaker particularly suitable for applications where precise generator and power-system protection is required.

With a rated operational voltage of 690 V AC, an ultimate short-circuit breaking capacity of 100 kA at voltages up to 690 V AC and a rated short-time withstand current of 100 kA for 1 s and 3 s, the E6.2H/f 5000 provides robust protection for critical electrical infrastructure. This WMP version is supplied as the withdrawable moving part and incorporates a fully rated neutral pole.
