Insulated Ferrules
Features
• Ferrules ensure reliable electrical connections when ter-
minating conductors in screw clamp terminal blocks.
• Fraying and breaking of wire strands is prevented and
the possibility of an unreliable connection is minimized.
• Insulated ferrules prevent conductor breakage due to
bending, wire stress or vibration, while facilitating wire
insertions into the terminal block clamp.
• Ferrules are the preferred alternative to twisting wire
stands or tinning the wire end before terminating into a
terminal block.
• Ferrules are thin-walled copper tubes, which are
mechanically crimped onto the ends of stranded wires.
• They are easy to use – simply strip the wire, slide the
ferrule onto the end of the wire and crimp.
How to Apply a Ferrule
• Strip the insulation from the end of the wire and insert
into the insulated end of the ferrule.
• Using the designated crimping tool, place the metal
shaft into the tool’s appropriate slot. Compress the tool
to make a crescent-shape depression along the length
of the ferrule.
• Insert the crimped ferrule into the terminal block.
• Tighten the ferrule and wire into the terminal block.
Materials
• High conductivity copper
• Tin plating
