A Crimping an OT or DT Terminal
Requirements for OT/DT terminals
● If a copper cable is used, use copper wiring terminals.
● If a copper-clad aluminum cable is used, use copper wiring terminals.
● If an aluminum alloy cable is used, use copper-to-aluminum wiring terminals,
or aluminum wiring terminals with copper-to-aluminum washers.
● Do not connect aluminum wiring terminals directly to the AC or DC terminal
block, as this may lead to electrochemical corrosion which aects the reliability
of cable connections.
● Comply with IEC 61238-1 requirements when using copper-to-aluminum wiring
terminals, or aluminum wiring terminals with copper-to-aluminum washers.
● Ensure that the aluminum side of the washer contacts the aluminum wiring
terminal, and the copper side contacts the terminal block.
