Insulated Hollow Ferrule Sofamel 50 mm² APF-50,00/20 Blue

Product Description

The Sofamel Insulated Hollow Ferrule 50 mm² APF-50,00/20 Blue is the termination solution for large-gauge stranded conductors where maximum electrical and mechanical reliability is required. The electrolytic copper sleeve with tinned finish provides a large contact surface that significantly reduces resistance and heating at the connection point. Its nylon (PA) insulating skirt with L1 20 mm (format /20) ensures firm guidance of the wire bundle, deep crimping, and stability against vibrations in power terminals. The blue color allows immediate identification of the gauge, streamlining assembly, inspections, and future interventions in high-performance electrical panels and switchboards.

Main Features

• Nominal section: 50 mm² for very high current stranded conductor.
• Capillary tube made of tinned copper with very low resistivity and excellent corrosion resistance.
• Insulation in injected nylon PA: high dielectric strength and mechanical resistance.
• Extended sleeve length: L1 = 20 mm for deep terminals and firm tightening.
• Color code: blue for visual gauge identification.
• Uniform crimping that eliminates loose strands and minimizes hot spots under full load.

Advantages or Benefits

• Extremely stable connection in very high current demand applications.
• Lower voltage drop and longer service life due to optimized metallic contact.
• Quick and standardized installation; reduces errors, rework, and downtime.
• Order and traceability of wiring through color coding.
• Professional finish that enhances the perceived quality of the electrical cabinet.

Purpose or Applications

Suitable for power panels, heavy machinery, distribution bars, large variable frequency drives, high-current contactors, renewable energy and storage systems, inverters/UPS, and industrial chargers. Ideal when it is necessary to terminate 50 mm² conductors with deep insertions and maximum robustness.

Technical Specifications

Compatibilities

Compatible with crimping pliers and dies for large-section ferrules, industrial screw or spring terminals, DIN terminal blocks, and power connectors.

The Sofamel Insulated Hollow Ferrule 50 mm² APF-50,00/20 Blue provides safety, order, and superior electrical performance, meeting the highest standards in professional high-current installations.
