Copper Disconnects
Making connections for high-amperage loads has never been easier!
High-Amperage Quick Power Disconnects
• Designed to be the fastest “off-load”
connection possible, while maintaining
system integrity
• Uses a multicontact approach to provide
low insertion and extraction forces with
low resistance and temperature rise
• Enables multiple connections and
disconnections without changing or
degrading performance characteristics
• Unique construction:
- Made from 99.9% conductive copper,
silver plated
- Contact design features louvered band
of beryllium copper
- All raised edges of louvered band
are deflected, producing a multitude
of high-force contact points
- Each contact point is typically in the
force range of 8,000 to 10,000 psi
- High currents, caused by short circuits
or sudden surges, make contact
interface even more efficient
by increasing contact pressure
