The FSTTB4 DIN rail terminal block combines a slim 6.2 mm profile with a 4-position, two-layer configuration for efficient cabinet wiring. Its pull-back spring connection provides secure, convenient conductor termination while supporting rigid wires up to 6 mm² and flexible wires up to 4 mm². Rated at 500V/32A under IEC standards and 300V/30A under UL requirements, it is built for dependable industrial applications. The PA66 housing features UL94 V-0 flame resistance, while tinned copper alloy conductors ensure stable electrical contact. REACH/RoHS compliance adds further installation confidence.
