Terminales de horquilla no aislados SNB (tipo TU)
SNB TU-type non-insulated fork terminals are copper terminals for bolted conductor connections. The source lists 43 models with distinct fork widths, bolt-hole sizes and body dimensions.
- Listed conductor groups span 0.5–10 mm²; the 14 and 22 groups have no stated conductor range.
- Group-specific Imax values range from 19 to 115 A in the catalog.
- Choose by exact model, conductor group and bolt-hole diameter.
Descripción general
SNB Non-Insulated Fork Terminals (TU Type) are copper fork terminals for bolted conductor connections. The supplied catalog lists 43 models across seven SNB groups, with group-specific material thickness and Imax values.
Características
- Non-insulated copper construction: the source identifies a bare copper terminal with no insulating sleeve.
- Fork connection: the fork tip is designed for a bolted connection; its bolt hole is listed for each model.
- Model-specific geometry: B, F and L vary by model, while E, D and d are specified by group.

Guía de selección
Match the conductor group and required bolt-hole diameter first. Compare B, F, L and barrel dimensions E, D and d against the available connection space, then quote the exact SNB model code.
