The ACB E4.2H is a 3P circuit breaker with a rated current (In) of 3200 A. It has an Icu rating of 100 kA at 415 VAC, indicating its ability to interrupt short-circuit currents. The breaker also has a rated short-time withstand current, Icw (1s), of 85 kA. It features a withdrawable auto EKIP touch LSIG trip unit, which provides protection against overload and short circuits. The shunt opening operates at 24 VAC/DC. The ACB E4.2H comes complete with WMP+FP+YO components. This circuit breaker is designed for engineers seeking a reliable solution for managing high currents and protecting electrical systems from faults and overloads.
