The Voltcraft measuring lead MSB-300 is optimized for electrical connections and low-voltage measurements in laboratories and workshops. The rated current is 10 A and the rated voltage is 30 V AC (alternating current) and 60 V DC (direct current). Extremely flexible: The cable material used is of exceptionally flexible quality. Unlike cheaper and stiffer materials, tangling is nearly impossible here. Increased tensile strength: Particularly tear-resistant plastic fibers enhance the 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. For your safety: The measuring lead is double insulated in two colors. If the first insulation layer is damaged, a differently colored insulation layer becomes visible. This wear indicator reliably shows when the cable is worn out. For safety reasons, damaged measuring leads should be replaced immediately. Secure contact: The hard-nickel surface coating of the 4 mm lamella connectors allows for a high number of plug cycles.
