Universal terminal blocks

Universal terminals OTL are designed for copper and aluminum conductors. The terminals are suitable for all types of copper or aluminum conductors with cross sections up to 300 mm². Multiple copper wires can be placed on the OTL terminal blocks according to the respective terminal type (see Table of universal terminals OTL wiring connectivity below). IP protection class for OTL terminals is IP20.

Certification and product safety

Universal terminals OTL are tested and certified by following standards:

  • EN 60947-7-1:2009 „Low-voltage switchgear and control gear – Part 7-1: Ancillary equipment – Terminal blocks for copper conductors“
  • EN 61238-1:2003 „Compression and mechanical connectors for power cables for rated voltages up to 30 kV (Um = 36 kV) – Part 1: Test methods and requirements“

All connectors used inside switchgears or similar appliances must fulfil these requirements.

EN 61238-1:2003 classifies connectors into two categories.

Class A undergoes heat cycle and short-circuit testing for electricity distribution and industrial networks.

Class B, only undergo heat cycle testing and are suitable for networks with rapid overload or short-circuit protection.

Universal terminals OTL are certified as Class A connectors, making them suitable for most applications. When choosing a connector, it is essential to ensure it bears the CE marking and Class A certification symbol, such as the FI mark, for reliable and safe electrical connections.
