## Summary description

Rittal AS 4051.617 sleeve ferrules for insulated wire termination. Copper tube with polypropylene insulation, sized for 0.75 mm² conductors, 12 mm length and 2.8 mm outer diameter. Supplied in pack of 500, these ferrules provide reliable conductor crimping, improved contact area and strand containment for control cabinets, panel wiring and machine installations.

## Long description

Rittal AS 4051.617 sleeve ferrules are crimp terminals designed for insulated wire termination on 0.75 mm² conductors. Each ferrule features a copper inner tube for reliable electrical contact and a polypropylene insulated collar to simplify insertion and prevent stray strands. With a length of 12 mm and an outer diameter of 2.8 mm, these ferrules are supplied in a pack of 500 and are intended for consistent, repeatable termination in control cabinets, panel wiring and machine installations.
Advantages
These sleeve ferrules combine a copper conductor sleeve with a polypropylene insulated collar to provide improved contact area, secure strand containment and reduced risk of wire separation during screw or clamp termination. The insulated collar eases handling and insertion into terminals while offering electrical insulation at the termination point. Supplied in a bulk pack of 500, they support efficient, high-volume wiring tasks and help maintain consistent crimp quality when used with an appropriate crimping tool.
Suitable for
 Termination of stranded wires with a nominal conductor cross-section of 0.75 mm²
 Control cabinet wiring and terminal blocks
 Panel building, industrial machinery and automation installations
 High-volume wiring tasks where consistent crimp quality is required
When it may not be suitable
These ferrules are sized specifically for 0.75 mm² conductors; they are not appropriate for significantly larger or smaller conductor cross-sections. They are intended for use with stranded wire and may not provide the intended benefit when used on solid conductors or conductors outside the specified size range. Proper crimping equipment is required to achieve reliable terminations; hand-twisting or incorrect tooling can lead to poor contact or conductor damage.
Key specifications
 Conductor cross-section compatibility: 0.75 mm²
 Inner sleeve material: copper
 Insulation collar material: polypropylene
 Total sleeve length: 12 mm
 Outer diameter: 2.8 mm
 Pack quantity: 500 pieces
How to use
Strip the stranded conductor to the appropriate length, insert the strands fully into the copper sleeve until the insulation collar seats against the wire insulation, and apply a suitable crimping tool matched to the ferrule size to form a secure mechanical and electrical connection. After crimping, inspect the termination to ensure the sleeve has compressed evenly around the conductor and that no stray strands are protruding. Insert the crimped ferrule into the terminal or clamp and tighten the screw to the manufacturer's recommended torque.
What to consider before purchase
 Confirm conductor cross-section; these ferrules are for 0.75 mm² stranded wire
 Verify the required sleeve length and outer diameter fit your terminal blocks and cable routing
 Ensure you have a compatible crimping tool for insulated ferrules of this size
 Buy an appropriate quantity for your project; this product is supplied in packs of 500
Usage recommendations
Use these ferrules with a dedicated insulated-ferrule crimping tool sized for 0.75 mm² to achieve repeatable, low-resistance terminations. Store unused ferrules in a dry environment to avoid contamination, and always follow terminal manufacturer torque specifications when fastening crimped conductors.
