Technical features

  • The housing of RS 4-16/4 and RSB 4-16/4 terminal blocks is made of high-quality imported plastics that have insulating properties as well as resistance to elevated temperatures, exceeding the characteristics of previously used materials (110°C without deformation). The material “NORYL” SEO, self-extinguishing category “Vo”, was used in their production.
  • The connectors are made of MS-line dim. 8 x 11 and galvanically protected for terminal type RS (RSB) 4-16/4.
  • The screws on the terminal contacts are in line with YUS MB1-111.Zn. and each contact is tightened with two screws.
  • A mechanism for hanging the terminal on a DIN 35 line is molded into the terminal housing on the underside.
  • The sealing cover is made of transparent LEXAN manufactured by “GE-Plastik” of the “Vo” self-extinguishing category.
  • One or more poles (for grounding) of the RS 4-16/1 type clamp can be added to the RS and RSB 4-16 clamps (with the help of a dovetail) if necessary.
  • With this new construction, many shortcomings that existed in previously applied terminals such as the RNSS 4-16 type terminal and others have been eliminated.


  • Primarily, the advantage and purpose of RSB series terminals is the possibility of sealing through the cover in the cabinets of measuring points in civil engineering from one meter.
  • The purpose of RS 4-16 type terminals has no limitations in terms of power terminals for all types of either industrial cabinets or any type of equipment containing electrical energy supply.
  • The label “ECO” means a more economical terminal in terms of price for situations where bridging is not required.
