Meets your requirements: The variable adjustable torque covers a wide range of applications. Increases your efficiency: The correct torque prevents material damage and rework. Reduces your costs: The correct torque protects against warranty claims. Provides full protection: Each tool has been individually tested at 10,000 V AC and is rated for 1,000 V AC. Application: Safe installation of terminals and couplings, conductor connections, and bolting of busbars. For work on live parts up to 1,000 V AC. When working on live parts, the safety of the user is the top priority. Especially when bolting busbars in distribution boxes, electricians are well-equipped with the insulated torque wrench featuring a 10-degree switching angle. The torque wrench with right/left rotation is ideal for powerful yet controlled tightening. By pulling and turning the end of the handle, the required torque value can be manually set according to the numerical scale. Additionally, the socket wrenches attached to the 3/8 inch square drive provide a secure grip thanks to the ball lock. When tightening with feel, the torque mechanism in the wrench noticeably gives way upon reaching the set torque value. The insulated torque wrench is subjected to a piece test according to the international standard EN/IEC 60900, allowing for safe work on live parts up to 1,000 V AC. To be used only with insulated Wiha socket inserts. DIN EN/IEC 60900.
