Hager HIC406A switch position indicator 4P 63A 400V load changeover switch

Automatic load changeover switch with switch position indicator 4P 63A 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).
