Specifications
Product Description
The Sofamel 4 mm² APF/D-4,00D Grey Insulated Double Hollow Ferrule provides a robust and professional termination when it is necessary to group two 4 mm² stranded conductors at a single connection point. The electrolytic copper sleeve with tinned finish ensures low contact resistance and excellent corrosion resistance, while the PA nylon cup keeps the wire bundle compact, provides insulation, and facilitates insertion into screw or spring terminals without damaging the conductor. It is the preferred choice for panel builders and technicians who require repeatable reliability in demanding electrical panels and switchboards.
Main Features
- Nominal section: 4 mm² per conductor (double ferrule/twin wire ferrule).
- Capillary tube made of tinned copper with high conductivity and oxidation resistance.
- Insulation in injected PA nylon, rigid and durable.
- Colour code: grey for immediate visual identification of the gauge.
- Uniform crimping prevents loose strands and hot spots during continuous operation.
- Approximate dimensions: L ≈ 18–19 mm; L1 ≈ 11–12 mm; D1 ≈ 7.0–7.5 mm; D2 ≈ 4.3–4.6 mm; Øi ≈ 3.1–3.3 mm.
Advantages or Benefits
- Greater electrical safety and mechanical stability of the connection.
- Optimizes current transfer and reduces contact losses.
- Speeds up series assembly and preventive/corrective maintenance.
- Order and tidiness in wiring with colour-coded gauge identification.
- Professional finish in accordance with best panel building practices.
Purpose or Applications
Recommended for advanced residential, tertiary, and industrial panels; distribution and control; variable speed drives, contactors, relays, power supplies, and modular terminals; instrumentation and PLC. Ideal when two 4 mm² cables are required to the same terminal without compromising reliability or panel aesthetics.
