Overview
YOCL ELECTRIC RHB Heat Shrinkable Ring Terminals combine a copper ring terminal with a heat-shrink sleeve for bolted wire connections. The 47 models cover three conductor-section groups, with different bolt holes and head dimensions.
Features
- Heat-shrink sleeve: provides insulated coverage around the wire barrel.
- Copper ring terminal: connects to a compatible bolted terminal.
- Color-coded sizes: red, blue and yellow distinguish the three conductor groups.
