Series 7400 VDE Kraftform adjustable torque handle 7444 VDE, 1.7-3.5 Nm, up to 1000 V - Wera 05074757001

Electricians have to observe defined tightening torques on terminals and switchgear while being protected against live voltage. The 7444 VDE torque handle combines both: it is insulated for safe work up to 1,000 volts, can be set by hand between 1.7 and 3.5 Nm and gives a distinct audible and perceivable signal when the value is reached.

Benefits

• Individually tested at 10,000 volts in accordance with IEC 60900 for safe working on live parts up to 1,000 volts
• Simple setting of the required torque by hand, easy-to-read scale with 0.10 Nm graduation
• Distinct audible and perceivable excess load signal when the pre-set torque is reached
• Unlimited loosening torque for seized screws
• Interchangeable blade system for Kraftform Kompakt VDE blades and control cabinet keys: removal by pulling down the release switch

Applications

For electrical installation, control cabinet construction and service on electrical systems where screws have to be tightened to a defined torque between 1.7 and 3.5 Nm. Blades are exchanged according to the required profile and selected separately.

Standards and safety

Insulated as per IEC 60900, each tool is individually tested at 10,000 volts and approved for work up to 1,000 volts. The measurement accuracy of ± 6 % complies with EN ISO 6789.
