Suitable for electrical installations, repair work, and prototyping where compact, reliable insulation and secure electrical contact are required.

## Long description

Prolech large wire connector for conductors with cross-section 0.5–0.75 mm² in brown, supplied in a pack of 100. This connector is designed to join solid and stranded copper conductors of the specified gauge, providing compact insulation and reliable electrical contact. The body material and internal contact geometry are intended for repeatable connections in electrical installations, repair work and prototyping, allowing either hand insertion or use with simple insertion tools.
Advantages
The connector offers a compact footprint and clear color coding for easy identification. It supports both solid and stranded conductors within the specified cross-section range and provides secure mechanical retention and electrical continuity when properly installed. Supplied in a bulk pack of 100, it is convenient for larger jobs and reduces the need for frequent restocking. The design permits quick splicing without soldering and simplifies repetitive installation tasks.
Suitable for
Household and light commercial electrical wiring tasks
Repair and maintenance of appliances and fixtures
Prototype circuit assembly and small electronics projects
Panel and junction box connections requiring compact insulated splices
Key specifications
Conductor cross-section compatibility: 0.5–0.75 mm²
Compatible conductor types: solid and stranded copper conductors
Color: brown for easy identification in multi-connector assemblies
Pack quantity: 100 pieces per package
Connection method: push-in style with internal metal contact for mechanical retention
How to use
Ensure power to the circuit is switched off and wires are de-energized before beginning work. Strip the conductor insulation to the recommended length for the connector, align the bare conductor with the connector entry and push the conductor fully into the contact until mechanical stop is felt. For stranded conductors, twist strands if needed to maintain compact insertion. If available, use a compatible insertion tool to ensure consistent depth and engagement. Verify secure retention by a gentle pull test and restore power only after confirming correct installation and insulation integrity.
Usage recommendations
Use these connectors within the specified conductor cross-section range and for copper conductors only. Avoid using on damaged or corroded conductors. Store in a dry environment to prevent contamination of internal contacts. For critical or permanent installations, follow applicable electrical codes and, if required, consult a qualified electrician.
