## Summary description

Rittal AS 4051.547 ferrules are crimp terminal end sleeves made of copper with polypropylene (PP) insulation, designed for 1.5 mm² (AWG 16) conductors. Each insulated sleeve is 10 mm long. Supplied in a pack of 4000 pieces, they ensure reliable conductor termination, improved contact area and protection against strand fraying in electrical assemblies.

## Long description

Rittal AS 4051.547 terminal ferrules are insulated crimp end sleeves for conductors with a nominal cross-section of 1.5 mm² (AWG 16). Constructed from copper with a polypropylene (PP) insulation collar, each ferrule measures 10 mm in overall length and is supplied in a pack of 4000 pieces. These ferrules are intended to provide a consistent, compact conductor end suitable for secure screw and clamp connections in control cabinets, distribution blocks and terminal strips.
Advantages
The copper tube ensures good electrical conductivity and low contact resistance while the polypropylene insulation collar provides mechanical protection and prevents strand fraying during termination. The standardized 10 mm length gives a reliable insertion depth for most common terminal blocks. Supplied in a large pack of 4000, these ferrules support high-volume wiring tasks with consistent quality and repeatability.
Suitable for
Crimping onto stranded copper conductors of 1.5 mm² (AWG 16)
Termination in screw-type terminal blocks, distribution terminals and relays
Industrial control panels, distribution boards and machine wiring
Pre-assembled cable harnesses and series production wiring
When it may not be suitable
These ferrules are designed specifically for 1.5 mm² conductors; they are not suitable for larger or smaller conductor cross-sections. They are also intended for copper conductors and should not be used with aluminium conductors without proper treatment or transition components. For applications requiring heat-shrink insulation or special environmental sealing, these standard polypropylene-insulated ferrules may not provide sufficient protection.
Key specifications
Conductor cross-section: 1.5 mm² (AWG 16)
Material (tube): copper
Insulation material: polypropylene (PP)
Insulation type: plastic collar
Overall length: 10 mm
Pack quantity: 4000 pieces
How to use
Strip the stranded conductor to the appropriate length so that the bare strands can fully enter the copper tube. Insert the conductor into the ferrule until the insulation collar sits against the end of the cable insulation. Use a suitable crimping tool sized for 1.5 mm² ferrules and apply a single clean crimp stroke to compress the copper tube evenly around the conductor. After crimping, visually inspect the ferrule for a secure mechanical fit and correct deformation, then insert the terminated end into the terminal and tighten the connection according to the terminal manufacturer's torque specification.
What to consider before purchase
Verify conductor material and cross-section are compatible (copper, 1.5 mm² / AWG 16)
Ensure available crimping tool dies are suitable for 1.5 mm² insulated ferrules
Consider whether a different insulation type (e.g., heat-shrink) is required for the application
Confirm that a pack of 4000 pieces matches your usage rate and storage needs
Usage recommendations
Use a calibrated crimping tool with the correct die for 1.5 mm² insulated ferrules to achieve reliable electrical and mechanical performance. For repetitive production work, inspect a sample of crimps periodically to confirm consistent compression and contact quality. Store ferrules in a dry environment to avoid contamination of the copper surfaces before installation.
