Automatic load changeover switch with switch position indicator 4P 100A 400V. Modular automatic load changeover switch with switch position indicator in accordance with IEC 60947-3 and IEC 60947-6-1 switches between source 1 (e.g. mains voltage) and source 2 (e.g. emergency power supply). In the event of a power failure, an integrated control system takes over the emergency power supply and when the power returns, the device switches back automatically. The DIN rail device with built-in padlock function is self-supplied via the feed-in. Measurement accuracy: frequency 1%, voltage 1%. Protection class: Class 1. Configuration is carried out using 4 potentiometers and DIP switches on the front of the device. Changeover switches ensure: - Stable positions (I - 0 - II), no impairment due to typical vibrations and shocks - Simple installation with effective ergonomics - Window with position indicator I - 0 - II - Integrated switch shutdown. Note: To accommodate up to 2 auxiliary contact blocks and 1 NOC auxiliary contact (for each position I -0 - II).
