VOLTCRAFT Highly Flexible Safety Test Lead [4 mm Lamella Plug - 4 mm Lamella Plug] 0.75 m White MSB-501 10 A (VC-8063515)

In electronics labs and industrial maintenance, technicians often need a test lead that can bend around tight corners without kinking or breaking. The VOLTCRAFT MSB-501 safety test lead meets that need with a highly flexible silicone jacket that stays supple even in cold environments. This single lead is equipped with stackable 4 mm lamella plugs on both ends, making it easy to chain multiple leads for complex measurement setups. Rated for 10 A and up to 1000 V CAT III / 600 V CAT IV, it provides reliable connections for multimeters, power supplies, and other test equipment.

• Extending measurement setups in electronics laboratories
• Safe testing in industrial control panels (CAT III/IV)
• Educational experiments requiring flexible, stackable leads

Good to know

The lead is sold individually, so order the quantity needed for your application. The white colour provides high visibility against dark backgrounds, reducing the risk of misconnection. Always verify that your equipment's input ratings match the lead's voltage and current specifications before use.
