What you need to know before choosing a mast terminal block

• in which voltage system you will use the terminal blocks (TN-C, TN-S)
• what is the cross section of the power line conductors
• how many terminals you require in the assembly (is tapping expected or not)
• what type of fuse carrier you will use
• whether you want to use the fuse carrier types offered

 What you may be interested in before choosing a pole terminal block and what benefits you will get from using these products:

- All terminal blocks assembled from RSA 6, RSA 10, RSA 16 terminals meet the legislative requirement of the standard - IP 20 protection. Types assembled from RSA 35 terminals must be supplemented with accessories (cover plate and side cover) to achieve IP 20 protection and only if the cross-section of the connected conductor is 10 mm2 and lower. If the terminal blocks assembled from RSA 35 terminals are not equipped with accessories, their protection rating is IP 10- You can connect both aluminium and copper conductors to all types of pole terminal blocks.All terminals in the pole terminal block assemblies are marked with a description on the marking strips - the insulation material used, all offered mast terminal blocks have a certificate of the state testing laboratory EZÚ Praha, declaration of conformity, also in the sense of EU legal standards, they bear the CE mark.

Mast terminal blocks are supplied as standard in dozens of different designs and combinations. In addition to these terminal blocks, atypical assemblies are also produced according to specific customer requirements.
