Fluorosilicone bearing grease improves reliability of circuit breakers

MOLYKOTE® brand Smart Lubrication™ technology from DuPont is enhancing the performance and reliability of electric utility high-voltage circuit breakers. Extensive field experience shows that lubricating breaker bearings with MOLYKOTE® 3451 Chemical Resistant Bearing Grease – a synthetic fluorosilicone oil thickened with PTFE – reduces failure rates and helps avoid equipment damage and power disruptions that can have significant customer service and financial impacts.

In utility circuit-breaker maintenance strategies, MOLYKOTE® 3451 Chemical Resistant Bearing Grease provides:

  • Longer lubricant life in harsh environments
  • Superior wear and corrosion protection
  • Reliability under heavy loads, in extreme heat and cold, and with intermittent operation
  • High resistance to oxidation and drying out
  • Prevention of sludge or varnish buildup

Deteriorated or inadequate lubrication is a common cause of circuit breaker failures. Electric utilities that lubricate breaker bearings with a synthetic fluorosilicone grease can help reduce failures significantly and improve overall reliability. MOLYKOTE® 3451 Chemical Resistant Bearing Grease lasts longer than other oils and greases in harsh environments. It is proven effective in preventing equipment damage, extending maintenance intervals and reducing power outages.

This fluorosilicone grease can help extend circuit breaker maintenance intervals up to 20 years or more and reduce problems and costs associated with slow trip times or failure to trip.
