The primary advantage is safety reliability - the forced mechanical linkage ensures all contacts operate simultaneously, preventing dangerous partial contact states that could cause equipment failure or safety hazards.
Inspect contact blades every 6-12 months depending on switching frequency. High-cycle applications may require quarterly inspections to check for wear, pitting, or contamination.
Yes, but they must be replaced as matched sets within the same contactor to maintain proper alignment and contact force distribution. Always follow manufacturer specifications for replacement procedures.
