Documentation

Certifications & approvals

UL (cULus)

Description

The F-U series fork cable lugs are made from electrolytic copper strip with a purity greater than 99.9% and undergo annealing and electrolytic tin-plating processes to facilitate crimping and increase resistance to mechanical stress.
They feature a PVC insulated cover with an internal funnel-shaped profile, designed to facilitate conductor insertion and help prevent wire kinking during wiring.
The internal knurling of the barrel improves contact between the conductor and the connector, helping to increase traction strength and ensure the long-term reliability of the connection.
