SHB Heat Shrinkable Fork Terminals (TU Type)
SHB TU-type heat shrinkable fork terminals combine a copper fork terminal with a heat-shrink sleeve. The catalog lists 29 models for 0.5–6 mm² conductors.
- Red, blue and yellow groups have separate Imax, tube thickness and E/D dimensions.
- Source operating range: −55 to +125 °C; initial shrink temperature: 80 °C.
- Select by conductor group, bolt-hole diameter and B/F/L dimensions.
Overview
SHB Heat Shrinkable Fork Terminals (TU Type) are copper fork terminals with heat-shrink sleeves for bolted conductor connections. The supplied catalog lists 29 models in red, blue and yellow conductor groups. Bolt-hole and B, F and L dimensions are specified by model.
Features
- Heat-shrink sleeve: the source gives an initial shrink temperature of 80 °C and a minimum temperature of 130 °C for complete shrinkage.
- Copper fork terminal: the conductive terminal material is listed as copper.
- Group-specific selection: conductor section, Imax, material thickness and E/D dimensions differ by group.
