Tri-Rated cable (also known as control panel wire or switchgear cable) is a fire retardant cable used in electrical cabinets, switch control, relay and instrumentation panels of power switchgear, and for internal connectors in rectifier equipment, motor starters and controllers. As a result, tri-rated cable has applications in most industries. These flexible, high temperature, flame-retardant, single core cables have a single layer of heat resistant polyvinyl chloride (PVC) insulation.
- Application: Heat resistant, flame retardant cable designed for use in the switch control, relay and instrumentation panels of power switchgear and for purposes such as internal connectors in rectifier equipment, motor starters and controllers. Tri-rated cable is sometimes referred to as BS 6231 cable, H07V2-K or panel wire.
- Suitability: For internal connectors in rectifier equipment, motor starters and controllers.

It derives its name from meeting the specifications of three separate standard-setting bodies – the British Standards Institute (BSi), the Underwriters Laboratories’ (UL) Appliance Wiring Materials (AWM), and the Canadian Standards Association (CSA) – hence making it tri-rated. This product’s triple rating makes it highly sought-after around the world as the triple certification of these cables enables their use in the North American markets as well as the European ones, which can result in a leaner and more flexible equipment manufacturing process. These cables are referred to as H05V2-K and H07V2-K under their European harmonisation (HAR) designation code.
British Standard Institute – British Standard BS6231 Type CK. This standard covers single core PVC insulated flexible electrical cables of rated voltage 600/1000V for switchgear and control gear wiring.
British Standard BS6231 Type CK specifications require this high temperature cable to operate at a maximum temperature of 90oC in continuous use, however tri rated cable has a maximum operating temperature of 105oC in order to also comply with UL758 and CSA 22.2 No.210. Tri-rated cable, panel wire manufactured to BS6231 Type CK, should not be confused with other cable manufactured to BS6231 Type BK which has a maximum conductor operating temperature of 70oC.
Canadian Standards Association – CSA 22.2 This standard specifies the requirement for flexible cords, elevator cables, and hoistway cables rated to a maximum of 600V.
UL 758 This standard specifies the requirements for flexible cords, elevator cables, electric vehicle cables, and hoistway cables rated up to 600V.
