## Long description

Connector BLOW 43-003# insulated wide screw 3.7 mm for 4.3 mm cable is a compact electrical connector intended for reliable joining, terminating and repairing of single-core conductors with a 4.3 mm conductor diameter. The device features a 3.7 mm screw that secures the conductor inside an insulated housing, while a wide contact area ensures stable electrical conductivity. The insulated body reduces the risk of accidental contact and supports safe handling in household and light industrial wiring tasks.
Advantages
The connector provides a wide contact surface that improves current transfer and reduces local heating. Its insulated housing offers protection against accidental short circuits and allows safer manipulation in confined spaces. The 3.7 mm screw design permits firm mechanical fixation of conductors, ensuring vibration-resistant connections. Its compact dimensions make it suitable for installations where space is limited while maintaining robust electrical contact.
Suitable for
Joining or splicing single-core cables with 4.3 mm conductors
Terminating wires in household electrical installations
Repairing damaged cable sections in light industrial equipment
Applications requiring insulated screw connections and space-saving components
Key specifications
Screw diameter: 3.7 mm
Designed conductor diameter: 4.3 mm
Insulated housing for electrical safety
Wide contact area for improved conductivity
Compact form factor suitable for confined spaces
How to use
Strip the cable insulation to the appropriate length, ensuring the conductor diameter matches the connector specification for a secure fit. Insert the conductor into the connector until it seats against the contact surface, then tighten the 3.7 mm screw to achieve mechanical and electrical fixation. Verify the firmness of the connection by gently pulling the conductor and, if required, apply additional tightening to meet local installation standards. Ensure the insulated housing remains intact and fully covers conductive parts to maintain safety.
Usage recommendations
Use the connector only with compatible single-core conductors of the specified diameter. Avoid over-tightening the screw to prevent conductor damage and ensure connections are made with power off. Inspect connections periodically for signs of looseness or corrosion, particularly in environments with vibration or humidity.
