## Summary description

Rittal AS 4051.580 insulated ferrules for wire terminations, composed of copper conductor with polypropylene (PP) insulation in yellow. Designed for 1.0 mm² conductor cross-section and 8 mm insertion length. Supplied as a pack of 500 pieces for reliable crimp connections in control cabinets, terminal blocks and electrical panels.

## Long description

Rittal AS 4051.580 insulated terminal ferrules are copper conductor end sleeves with a polypropylene (PP) coloured insulation designed for terminating 1.0 mm² solid or stranded conductors. Each ferrule provides an 8 mm insertion length and a plastic collar that stabilises the crimp and helps guide the conductor into terminal blocks and screw connections. The product is supplied in a pack of 500 pieces and is intended for making reliable, low-resistance crimp connections in control cabinets, distribution panels and electrical assemblies.
Advantages
These ferrules combine a tin-plated copper barrel for good conductivity with a yellow PP insulation that offers mechanical protection and clear visual identification. The plastic collar improves insulation retention and supports repeatable crimping quality when using a suitable crimping tool. The 8 mm insertion length is compatible with common terminal blocks and screw-type connectors, ensuring stable electrical contact and reduced risk of stray strands or loose connections.
Suitable for
Terminating 1.0 mm² conductors in control cabinets and switchgear
Electrical panels, distribution blocks and terminal strips
Industrial and commercial wiring where repeatable crimp quality is required
Applications requiring colour coding for circuit identification
When it may not be suitable
This ferrule is designed specifically for conductors with a 1.0 mm² cross-section and an 8 mm insertion depth. It is not suitable for larger or smaller conductor sizes; using the wrong ferrule size can result in poor crimps or unreliable electrical contact. It is also not intended for direct high-temperature or high-vibration applications unless paired with appropriate strain relief and installation practices.
Key specifications
Conductor material: copper (tinned)
Insulation material: polypropylene (PP), coloured yellow
Nominal conductor cross-section: 1.0 mm²
Insertion/crimp length: 8 mm
Plastic collar for improved insertion and retention
Pack quantity: 500 pieces
How to use
Strip the conductor to the specified length to expose the bare conductor matching the 8 mm insertion length. Insert the conductor strands fully into the ferrule barrel until the insulation collar seats against the wire insulation. Use a calibrated crimping tool designed for insulated ferrules to make a single, firm crimp at the barrel location. After crimping, inspect the connection for exposed strands and verify mechanical retention by a gentle pull test before inserting into the terminal block or screw connector.
What to consider before purchase
Verify conductor cross-section is 1.0 mm² to ensure proper fit and crimp quality
Confirm 8 mm insertion length is compatible with your terminal blocks or screw connections
Ensure you have a compatible crimping tool for insulated ferrules to achieve reliable crimps
Consider colour coding needs—yellow insulation is useful for identification
Usage recommendations
For consistent results use a dedicated insulated-ferrule crimping tool and match ferrule size to conductor cross-section. Store packs in a dry environment and handle crimps with care to maintain low contact resistance and secure mechanical retention in electrical panels and control cabinets.
