5574V 1000V Insulated Dismantling Knife | VDE

Q1: What is the mechanical difference between 5572V and 5573V?

A: The 5572V features an injection-molded plastic back guard covering the spine of the blade. This insulation prevents short circuits if the back of the knife makes contact with adjacent energized terminals or busbars. The 5573V has a solid, fully exposed blade extending directly from the handle without plastic backing, allowing full blade depth for slicing thicker cable jackets and heavy rubber conduit.

Q2: What is the primary function of the 5574V dismantling knife?

A: The 5574V is a specialized dismantling knife (Abmantelungsmesser) designed specifically for slitting open the tough outer protective sheath of multi-core electrical cables. Its cutting edge is shaped to peel outer jacketing away cleanly without cutting into or damaging the insulation of the inner conductors.

Q3: Are these cable knives certified for live-line working?

A: Yes. The 5572V, 5573V, and 5574V are certified to IEC 60900 and DIN EN 60900 standards and tested up to 10,000V AC to ensure safety for live electrical work up to 1,000V AC and 1,500V DC.

Q4: Do these knives come with safety covers?

A: Yes. Each knife includes a transparent, impact-resistant protective sheath that snaps over the blade to prevent accidental cuts during storage and to protect the cutting edge from damage.
