Meets your requirements: Variable adjustable torque covers a wide range of applications. Increases your efficiency: The right torque protects you from material damage and rework. Reduces your costs: The right torque protects you from warranty claims. Offers you full protection: Each tool is individually tested at 10,000 V AC and approved for 1,000 V AC. Application: Safe installation of terminals and sleeves, conductor connections, screwing busbars. For work in the area of live parts up to 1,000 V AC. When working on live parts, the safety of the user is the top priority. Electricians are well equipped with the insulated torque wrench with a 10° switching angle, especially when screwing busbars in the distribution box. The torque wrench with clockwise/anticlockwise rotation is therefore ideal for powerful but controlled tightening. By pulling out and turning the end of the handle, the required torque value can be set by hand using the numerical scale. Furthermore, the socket wrenches fitted to the 3/8' square drive offer a secure hold thanks to the ball lock. When tightened carefully, the torque mechanism in the wrench bends noticeably when the set torque value is reached. The insulated torque wrench is subjected to a routine test in accordance with the international standard EN/IEC 60900 and enables safe work in the area of live parts up to 1,000 V AC. Only to be used with insulated Wiha socket wrench inserts. DIN EN/IEC 60900.
