Liquid ingress protection is a critical element to
keeping electrical systems operational. Exposure
to water in indoor or outdoor applications, dust in
suspension, condensation and accidental spills
of machine oils and lubricants can all shorten the
life of your electrical system. One drop can be
enough to ruin your production, so when specifying
electrical components for mining and mineral
processing applications, consider the following
issues related to liquid ingress:
• Liquid exposure can cause deterioration of electrical
connections or short circuits
• Electrical system components designed with round
surfaces help to shed contaminants, rather than
creating a shelf where they can collect
• Abrasive and corrosive mine waters combined with
moisture present extra challenges for liquidtight
electrical components in mining and metal applications
• Appropriate product design, materials and labor skills
are required to ensure reliability, maintainability and
safety of electrical connections subject to liquid and
dust ingress
Thomas & Betts electrical solutions offer protection
against liquid, moisture and dust ingress.
