The SMISSLINE TP Power Bar for 400A features a plug-in socket system that allows for the connection of plug-in protective devices to the external conductors L1, L2, L3, and N. This system ensures that devices and components can be plugged in and unplugged under voltage without load. Smisline TP is fully finger-safe - IPxxB. Integrated auxiliary busbars LA and LB can be used to supply control circuits (auxiliary contacts, etc.). Directly pluggable protective devices can be connected to the system at any position (within the grid dimensions). Additional DIN rail devices can be integrated into the system using universal adapters. Complete touch protection is only guaranteed with the SMISSLINE TP socket end piece.
