This Hammond 4x10 inch Bus Bar has 0.25 inch tin plated copper rated 3200V glass-reinforced thermoset insulators.

Benefits

• Electro tin plated copper bus bar, 100/300 micro inches of plating
• The thin tin coating acts as a shield, inhibiting copper oxidization
• Copper oxidization causes a poor electrical contact which then gets hot and increases the copper oxidization rate
• Oxides, because of their poor conductivity, also cause arcing at the electrical contacts, eroding the copper
