The SMISSLINE TP Power Bar plug-in base system for 400A is used to connect the plug-in protective devices to the outer conductors L1, L2, L3 and N. The system ensures that devices and components can be plugged in and unplugged without any load when live. Smisline TP is completely finger-safe - IPxxB. Integrated auxiliary busbars LA and LB can be used to supply control circuits (auxiliary contact or similar). Directly plug-in protective devices can be plugged into the system at any position (within the grid dimensions). Additional DIN rail devices can be integrated into the system using universal adapters. Complete contact protection is only guaranteed with the SMISSLINE TP base end piece.
