FI/LS switch, 6 kA, 4P type A, 30 mA, B-Char, In: 16A Un: 400V FI/LS switch SENTRON 5SU1 for combined protection against overload, short circuit and residual currents. Our FI/LS switches (RCBO) are VDE-tested and certified according to DIN EN 61009-1, DIN EN 61009-2-1. With their double-chamber terminals, the connection of conductors with different cross-sections is very easy. Other Siemens SENTRON protective switching devices can be connected quickly and easily to the 5ST3 pin busbars. The Datamatrix code on the device gives you quick access to all technical data in the Siemens Industry Online Support app.The SENTRON protective switching devices can be expanded to include many functions using the consistent accessories from the modular system.Optimal technology for your safety - only from Siemens.
