But increasing safety requirements have created an immediate need to reduce the potential for arc flash even further. OSHA, for example, uses the new requirements of NFPA 70E to judge whether an employer \u201cacted reasonably\u201d in protecting its workers from these arc flash hazards.\n\t\t\t\t\t<\/div>\n\t<\/div>\n<\/div>\n\n<div class=\"read-more-wraper\">\n\t\t\t<a class='read-more' href=https://eecoonline.com/brand/'//inspire//mitigating-arc-flash-hazards-with-current-limiting-fuses'>/n/t/t/tRead More ><\/a>\n\t<\/div>\n","slug":"mitigating-arc-flash-hazards-with-current-limiting-fuses","view_link":"\/inspire\/mitigating-arc-flash-hazards-with-current-limiting-fuses","action_configuration":{"update":false,"delete":false}},{"id":"98","title":"New VFDs Require High Speed Fusing Protection","first_topic_name":"Automation","second_topic_name":"Mersen","description":" Over the years major manufacturers have removed internal semiconductor fuses to cut costs.
