## Summary description

Rittal AS 4051.543 is an insulated wire end ferrule for terminating 1.5 mm² conductors.

Supplied in a pack of 4000, these ferrules provide reliable, secure conductor connections for control cabinets, terminal blocks and industrial wiring.

## Long description

Rittal AS 4051.543 insulated wire end ferrules are designed for terminating and protecting 1.5 mm² conductors in electrical and control wiring. Each ferrule features a copper crimp sleeve for reliable electrical contact and a red polypropylene (PP) insulation collar to support insertion into terminal blocks and to prevent strand fraying. The ferrules are 8 mm long with a smooth outer diameter and are supplied in a bulk pack of 4000 items for larger installation projects and maintenance tasks.
Advantages
These ferrules combine a copper crimp barrel with a polypropylene insulation collar to deliver consistent electrical conductivity and mechanical protection. The insulated collar improves handling and guides the conductor into screw terminals, reducing the risk of stray strands and short circuits. Supplied in a large pack, they are convenient for frequent use in panel building and service operations, offering uniform quality across many terminations.
Suitable for
Termination of multi‑strand conductors with a nominal cross‑section of 1.5 mm²
Wiring inside control cabinets, terminal blocks and distribution panels
Industrial and commercial electrical installation and maintenance work
Applications where consistent crimp quality and protection against strand splaying are required
When it may not be suitable
These ferrules are specifically sized for 1.5 mm² conductors; they are not suitable for larger or significantly smaller conductor cross‑sections. They are intended for insulated termination into screw or clamp type terminals and may not be appropriate where non‑insulated or special high‑temperature terminations are required.
Key specifications
Conductor cross‑section: 1.5 mm²
Ferrule length: 8 mm
Insulation material: polypropylene (PP)
Barrel material: copper
Insulation colour: red
Packed quantity: 4000 pieces
Outer diameter: approximately 4 mm
How to use
Strip the conductor to the correct length, insert the strands fully into the copper crimp sleeve until they reach the base of the insulation collar, then crimp securely using an appropriately sized insulated ferrule crimping tool. After crimping, check that the ferrule is firmly attached and that no stray strands protrude. Insert the terminated conductor into the terminal block or clamp and tighten the terminal screw to the manufacturer‑specified torque.
What to consider before purchase
Confirm conductor cross‑section is 1.5 mm² to ensure compatibility
Verify required ferrule length and outer diameter for your terminal type
Consider pack quantity (4000 pieces) relative to project needs and storage
Ensure a compatible crimping tool is available for reliable terminations
Usage recommendations
Use a quality ratchet or press crimping tool sized for 1.5 mm² ferrules and follow terminal manufacturer torque ratings. Store unopened packs in a dry environment to prevent contamination and keep ferrules in original packaging until use to maintain consistent handling and traceability.
