## Summary description

Rittal AS 4051.583 crimp ferrules for insulated conductors, made of copper with polypropylene (PP) insulation in red. Designed for 1.5 mm² conductors, 8 mm tube length and 4 mm outer diameter. Supplied as 500 pieces per pack for reliable wire end termination in electrical panels, control cabinets and field wiring.

## Long description

Rittal AS 4051.583 crimp ferrules are insulated wire end sleeves designed for reliable termination of 1.5 mm² conductors. Each ferrule features a copper tubular insert with a red polypropylene (PP) insulation collar, 8 mm tube length and approximately 4 mm outer diameter. Supplied in a pack of 500, these ferrules are intended for use in electrical panels, control cabinets and field wiring where consistent, low-resistance connections and protection of stranded conductors are required.
Advantages
These ferrules provide a secure mechanical and electrical connection by compressing the copper tube onto stranded conductors, reducing strand splaying and ensuring a consistent contact surface. The polypropylene insulation collar aids insertion into terminal blocks, prevents insulation damage, and provides color coding for quick identification. The 8 mm tube length and 4 mm outer diameter are shaped to fit common terminal sizes for 1.5 mm² conductors, and the large pack quantity supports installations and maintenance tasks without frequent reordering.
Suitable for
Termination of 1.5 mm² stranded copper conductors in control cabinets and distribution panels
Field wiring and junction boxes where insulated ferrules improve connection reliability
Applications requiring color-coded identification and repeated use across multiple connections
When it may not be suitable
These ferrules are specifically sized for 1.5 mm² conductors; they are not suitable for larger or smaller conductor cross-sections. They are intended for copper conductors — use appropriate ferrules or terminals for aluminum or bimetallic conductors. In applications that require uninsulated ferrules, soldered joints, or specialized high-temperature materials, these standard polypropylene-insulated ferrules may not meet the requirements.
Key specifications
Conductor cross-section: 1.5 mm²
Tube length: 8 mm
Outer diameter (approx.): 4 mm
Material (tube): copper
Insulation material: polypropylene (PP)
Insulation colour: red
Pack quantity: 500 pieces
How to use
Strip the conductor to the appropriate length so that the bare strands fully enter the copper tube. Insert the stripped end into the ferrule until the insulation collar meets the conductor insulation. Use a compatible crimping tool sized for 1.5 mm² ferrules and apply a single, firm crimping action to compress the copper tube onto the conductor. After crimping, verify mechanical retention and electrical continuity. Insert the ferrule into the terminal and secure the terminal connection according to the terminal manufacturer's instructions.
What to consider before purchase
Confirm conductor type and cross-section are copper stranded conductors of 1.5 mm².
Check terminal block or connector dimensions to ensure compatibility with 8 mm tube length and ~4 mm outer diameter.
Ensure a crimping tool compatible with insulated ferrules for 1.5 mm² is available.
Consider pack quantity (500 pieces) relative to project needs and storage.
Usage recommendations
For reliable joints, use a quality ferrule crimper sized for 1.5 mm² ferrules, strip the conductor to the correct length, and inspect each crimp for firm mechanical retention. Use the red insulation colour for circuit identification where standard colour coding is applied.
