Unique-Bargains 12 Position Dual Row Type H Wire Cap Connector 20A 380V Pack of 5

12-Position Dual-Row Wire Cap Connector

This 12-position dual-row wire cap connector handles 20 A at 380 V. Each unit accepts cables up to 4.4 mm in diameter and uses slot-type screws on a 10 mm and 13 mm pitch. The pack contains five transparent PC-insulated blocks with brass contacts and zinc-plated iron screws. It suits lamp, lighting, appliance and distribution-box wiring.

Practical Limits of the Screw Terminal Interface

The screw-terminal barrier strip tops out at 20 A and 380 V, so circuits beyond those ratings need a different connector. Cable entry is fixed at 4.4 mm, limiting conductor size. The 10 mm and 13 mm screw spacing sets the minimum wire-bend area. Only slot-drive tools can tighten the screws, and the PC housing defines the operating temperature envelope.

When to Replace Older Terminal Strips

This block replaces cracked or oxidised strips in lighting, appliance and distribution cabinets where 12 positions in two rows are required. The jump is worth it when the existing hardware cannot accept 4.4 mm conductors or has lost insulation integrity. It does not suit builds needing more than 12 positions, higher current than 20 A, or a different screw pitch.
