Motor-operated load changeover switches meet the device standards 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 motor-operated mains changeover switches. The switches can also be used in the AC and DC range. The switches can be mounted horizontally, vertically and flat. Depending on the type, the control voltage of the motor is 240 V DC, 110 V-240 V AC / DC, 24 V DC, 48 V DC, 110 V-125 V AC / DC and 220 V-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. As accessories, ABB offers black handles for emergency operation, auxiliary contacts, fourth poles, N and PE terminals, terminal covers, connection terminals and much more.
