## Summary description

Rittal AS 4051.620 is a pack of 500 insulated ferrules made of copper with polypropylene (PP) insulation in red. Designed for 1.0 mm² conductors and 12 mm length, these crimp end sleeves provide reliable conductor termination, improved contact surface and strain relief for electrical panels, control cabinets and wiring harnesses.

## Long description

Rittal AS 4051.620 ferrules are insulated crimp end sleeves designed for safe and reliable termination of 1.0 mm² copper conductors. Each pack contains 500 red polypropylene (PP) insulated ferrules with a 12 mm insulated sleeve length. These ferrules improve electrical contact, protect stranded wires from fraying, and provide strain relief in control cabinets, terminal blocks and wiring harnesses.
Advantages
The PP-insulated collar ensures secure insertion into terminals and reduces the risk of short circuits by covering exposed conductor ends. Copper construction provides good electrical conductivity and corrosion resistance for standard indoor electrical installations. The 12 mm sleeve length accommodates insulated connections and helps maintain consistent crimping quality when used with appropriately sized crimping tools.
Suitable for
Termination of 1.0 mm² stranded copper conductors
Wiring in control cabinets and distribution panels
Terminal block and relay connections in industrial equipment
Electrical harness assembly and maintenance
When it may not be suitable
These ferrules are intended specifically for 1.0 mm² conductors; they are not suitable for larger or smaller wire cross-sections. They are designed primarily for general indoor electrical and control applications and are not intended for direct exposure to harsh outdoor environments or continuous high-vibration conditions without verifying compatibility with the specific installation.
Key specifications
Conductor cross-section: 1.0 mm²
Material (inner): copper
Insulation material: polypropylene (PP)
Insulation length: 12 mm
Color: red
Pack quantity: 500 pieces
How to use
Strip the conductor to the appropriate length, insert the stranded wire into the ferrule barrel until the insulation collar meets the conductor insulation, and crimp the ferrule using a matching crimping tool or ratchet crimper sized for 1.0 mm² ferrules. After crimping, visually inspect the connection for complete compression and that no strands remain outside the barrel. Insert the ferrule into the terminal and secure the terminal screw or clamp according to the equipment manufacturer's instructions.
What to consider before purchase
Verify conductor cross-section is 1.0 mm² and that wires are stranded, not solid
Confirm compatibility of your crimping tool with 1.0 mm² insulated ferrules
Check required insulation color coding for your installation (red)
Ensure the 12 mm insulation length fits terminal depth and clearance constraints
Usage recommendations
Store ferrules in a dry, dust-free environment and use a proper insulated crimping tool to achieve consistent, reliable terminations. For installations subject to vibration or outdoor exposure, assess additional protective measures or select ferrules and terminals rated for those conditions.
