Metallic Bimetal Strip for Relay Thermal Protection from China
A bimetallic strip made of two bonded metallic alloys for thermal snap-action relays under HTS 8536.30.40. It mechanically deforms when heated to open or close electrical contacts, providing over-temperature protection. Reacts mechanically to temperature changes per subheading requirements.
