## Summary description

Insulated quick connector by Prolech for electrical wires with cross-sections from 0.5 to 1.0 mm². Red, large size, supplied in a pack of 100.

## Long description

Prolech insulated quick connector large 0.5–1.0 mm² red, pack of 100 is a compact insulated splice designed for fast joining of single-core electrical conductors with cross-sections from 0.5 to 1.0 mm². The red large-size connector is intended for applications where reliable electrical contact and insulation are required, such as automotive wiring, household electrical repairs and lighting circuits. Supplied in a pack of 100, it supports repeated use in workshop or production environments and simplifies cable joining with a crimp or tool-assisted insertion method.
Advantages
The connector combines insulation and contact in one component, reducing the need for additional heat-shrink tubing or separate insulating sleeves. Its design allows consistent contact pressure on conductors, which improves electrical continuity and reduces the risk of intermittent connections. The red colour provides quick visual identification of the conductor size range, and the bulk packaging of 100 pieces offers convenience for larger projects or inventory stocking.
Suitable for
Automotive wiring repairs and splices
Household electrical repairs and small appliance wiring
Lighting circuits and fixture connections
Workshop assembly and maintenance tasks
Key specifications
Conductor cross-section compatibility: 0.5–1.0 mm²
Connector size: large (red colour code)
Insulation: integrated insulated housing for protection against short circuits
Packaging: pack of 100 pieces for bulk use
Intended conductor type: single-core (solid) wires
How to use
Strip approximately 5–7 mm of insulation from each conductor, insert the stripped ends into the connector until they meet the internal contact, and apply a crimping tool or the specified insertion tool according to standard practice for insulated quick connectors. Verify that the conductors are held firmly and perform a pull test to confirm mechanical retention. After joining, ensure the insulated housing fully covers exposed conductors and that the connection is not under mechanical strain.
Usage recommendations
Use the connector within its specified conductor range (0.5–1.0 mm²) and select the appropriate crimping or insertion tool to achieve reliable electrical contact. Avoid using the connector on stranded cables unless the cable is compatible with the connector type and appropriate ferrules or preparation methods are applied. Store the pack in a dry environment to preserve insulation integrity and inspect connections visually and electrically after installation.
