The 10 is a two-pole jumper accessory designed for use with BUCHANAN 100 Series High Density Miniature terminal blocks. This jumper facilitates electrical connections between adjacent terminal positions, enabling flexible circuit configuration without requiring additional wiring. The jumper is compatible with Miniature nylon, Miniature polypropylene, and Single Tier block variants, as specified in the accessory compatibility table. It supports wire ranges from #30 to #12 AWG and operates at rated voltages of 300V for Miniature blocks and 600V for Single Tier blocks. The 10 jumper is commonly used in control panel applications and industrial electrical systems where space-efficient, modular terminal block configurations are required.
