The ACB E4.2H is a high-rated current circuit breaker with a capacity of 3200 A and 3-poles. 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, short circuits, and ground faults. The ACB E4.2H is equipped with shunt opening and closing mechanisms, as well as a motor operator that operates on 110-120 VAC/DC power. To ensure complete functionality, the ACB E4.2H comes with additional components including WMP, FP, YO, YC, and MOP. This circuit breaker is designed to meet the needs of engineers seeking reliable protection for electrical systems with high current requirements.
