General: The OTL universal connectors offer the highest quaility product with versatile features for many industries. The connectors can be used for both copper and aluminium cable offering a wider cable selection than other universal connectors on the market. The connectors are supplied with pre-greased contact spaces, whilst the connections are made with hex screws guarantee easy, secure and quick installation.
The compact size and DIN rail or screw mounting of the connectors ensures efficient use of the space in tighter installation spaces.
Use: OTL universal connectors are used for the branching and connecting aluminium and copper cables. These small modules offer high power connections for the EV charging, Solar and Windfarm applications as well as many other uses.
Materials: The body of the OTL connectors is tin plated aluminium whilst the insulating cover is made of UL 94 V-0 polyamide.
