FST4-HT is built for fixed industrial wiring where a larger conductor interface is required without resorting to screw-clamp termination. Its pull-back spring connection provides efficient wire insertion and a secure connection, while the four-position layout helps keep multi-circuit assemblies organized. Copper-alloy contacts with tinned surfaces support dependable electrical continuity, and PA66 insulation with UL94 V-0 flame resistance adds a strong safety foundation. This terminal is well suited to control cabinets, automation equipment, power distribution assemblies, and other demanding industrial wiring applications.
