Automatic changeover switch for mains generator 4x630A. Load changeover switch with motor drive for generator/mains according to DIN EN 60947-3 and DIN EN 60947-6-1 for remote switching of 2 low-voltage circuits with safety separation for installation in distribution boards. The changeover switch consists of two load-break switches arranged one above the other with locking and remote drive.
Function:

• 3 stable switching positions (I-0-II) and automatic switching under load from one position to the other safety separation with switch position indicator
• manual emergency switch handle
• generously dimensioned connection rails that enable the use of connecting rails
• integrated control unit for automatic switching
• application especially for mains/generator replacement
• use with temporary interruption of the load supply, i.e. not uninterrupted.
With standby relay with constant monitoring of the availability of the device, integrated auxiliary switch (SÖ) for each switching point and automatic or manual switching selectable.
Note: Manual locking with a padlock is possible.
