The DERANCOURT CD4 20 Insulated Ratchet Torque Wrench (4–20 Nm) is a precision-engineered tool designed for controlled tightening in live electrical environments. Certified to EN IEC 60900 for electrical insulation (up to 1000V AC / 1500V DC) and EN ISO 6789 Type II Class A for torque accuracy, it provides both safety and reliability for electricians and professionals working near live parts.
With a graduated torque adjustment range of 4–20 Nm, this insulated torque wrench ensures high precision. The torque value, displayed in Nm or Lb/ft, is set by turning the rear handle and aligning the graduation with the vertical dial mark. A secure locking mechanism prevents accidental torque loss during operation.
Functioning like a ratchet spanner, the CD4 20 releases the handle by approximately 7° with a clear audible click once the preset torque is reached. It then automatically resets, ready for the next tightening sequence. The right-step ratchet system ensures smooth and efficient tightening, while the insulated handle offers maximum protection against electrical hazards.
