Currently, the housing of FEMAN’s terminal blocks is made exclusively from the highest quality imported plastic materials, self-extinguishing V-0, and has an insulation value of 750 V, as well as heat resistance to 1100°C without deforming. The block bases are constructed to fit all types of existing rails. FEMAN VS-clamps are completely made according to VDE – DIN standards for this type of product. Along with additional sizes of clamps ( 2,5 – 35 mm2 ), FEMAN makes all the accompanying gear/elements. In recent years, FEMAN has proven the quality of their terminal blocks, and the best evidence of this is the several million elements of all different sizes delivered and installed.
