The name Tri-Rated comes from the fact that the cable meets the specification of three seperate standards. These being the British Standards Institute (BSi), the Underwriters Laboratories (UL) Appliance Wiring Materials (AWM), and the Canadian Standards Association (CSA) - hence the name tri-rated.
Tri-Rated cable (also known as BS6231 control panel wire or switchgear cable) is a fire retardant cable used in electrical cabinets, switch control, relay and instrumentation panels of power switchgear.
Triple certification of tr-rated cable enables their use in the North American markets as well as the Europe. These cables are referred to as H05V2-K and H07V2-K under their European harmonisation (HAR) designation code.
Tri-rated cable is designed and manufactured to be used in the wiring of electrical cabinets, switch control, relay and instrumentation panels of power switchgear. It can also be used for internal connectors in rectifier equipment, motor starters and controllers. Tri_rated cable is also designed for use inside small electrical devices. As a result, tri-rated cable has applications in most industries.
