Universal terminals OTL are designed for copper and aluminium conductors. The terminals are suitable for all types of copper or aluminium conductors with cross-section up to 300 mm². Multiple copper wires can be placed to the universal terminals OTL blocks according to the respective terminal type. IP protection class for OTL terminals is IP20.
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.
