常见问题

What is the purpose of silver plating on fixed contacts?

Silver plating reduces contact resistance, improves conductivity, provides better arc resistance, and prevents oxidation for more reliable electrical connections.

How often should fixed contacts be inspected?

Inspect every 6-12 months or after 100,000 operations, checking for pitting, wear, discoloration, and proper contact pressure.

Can fixed contacts be replaced individually?

Yes, but must be replaced as matched sets with moving contacts to ensure proper alignment and contact pressure.
