Automatic load changeover switches meet the device standards DIN EN 60947-1, DIN EN 60947-3 and DIN EN 60947-6-1. The switches have an open switch (I-0-II) and are suitable for use as an automatic mains changeover switch. An OMD control unit is included. The control voltage of the motor is between 220 V and 240 V AC. The motor drive is controlled via a button or a central control center. The supplied handle for the emergency operation can optionally be locked in the OFF position. Remote control is prevented by mounting the handle or by mounting a lock. The switches can also be used in the AC and DC range. The automatic load changeover switches can be mounted vertically, horizontally and flat. The switches are available in compact versions from 40 A to 125 A. As accessories, ABB offers black handles for emergency operation, auxiliary contacts, fourth poles, N and PE terminals, terminal covers, connection terminals and much more.
