Leakage characteristics

Type AC: Operates with AC Type A: Operates not only with AC but also with pulsating current <Reference> TYPE B: Operates with DC More Details >>

MCCB, ELCB and ACB at higher altitudes

In that case, the rated current and the rated voltage shall be reduced. Refer to the table of derating factors as below. More Details >>

ACB DC use

It is not possible to use standard AE-SW in DC circuit. Special DC use AE-SW is provided if specified. More Details >>

ACB closing time

The time between application of voltage to the closing coil (CC) and closing of the main contact is 0.08 sec or less. More Details >>
