The Voltcraft safety measuring lead MSB-501 is optimized for electrical connections and measurements in laboratories and crafts. The nominal current is 10 A, and the nominal voltage is 1000 V AC (alternating current) and 1000 V DC (direct current). According to CAT IV, the nominal voltage is 600 V AC and 1000 V DC. Extremely flexible: The cable material used is of exceptionally flexible quality. Unlike cheaper and stiffer materials, tangling with the Voltcraft MSB-501 is nearly impossible. Increased tensile strength: Particularly tear-resistant plastic fibers enhance tensile strength and extend the lifespan. Heat resistant: The measuring lead is insulated with silicone and is resistant to heat damage that can occur when working with hot soldering irons. Secure contact: The hard-nickel surface coating of the 4 mm safety lamella connectors allows for a high number of mating cycles.
