DIN-VDE 0620-1 Gauge 16c Test of Maximum Withdrawal Force AC 400/230 V 25 A

This DIN-VDE 0620-1 Gauge 16c is specialized in testing the maximum withdrawal force of AC 400/230 V 25 A plugs (3P + N + PE), strictly complying with the specifications of the DIN VDE 0620 series standards. It is an indispensable quality and safety verification tool for plugs and matching fixed sockets in household and similar applications, ensuring that the plug maintains a stable and reliable connection with the socket during operation. By verifying the withdrawal force, it prevents accidental disconnection that may cause electrical failures, equipment damage, or safety hazards.

Specifications:

• Complies with DIN VDE 0620-1 and DIN VDE 0620-2-1:2021-02 standards
• Applicable plug type: 3P + N + PE, AC 400/230 V 25 A
• Pin roughness: Rz 1.5 – Rz 2.5
• Key dimension: ø4.87 (tolerance: 0.00)
• Additional dimension: 2.6 (relevant specification as per product design)
• Critical requirement: The specified diameter shall not be exceeded when measured 19 mm from the plug’s front face
• Materials: – Body and pins: Hardened stainless steel – Handle: Insulating material (type selected by the manufacturer) – Auxiliary components: Insulating material (type selected by the manufacturer)

Test Procedures:

• Prepare the AC 400/230 V 25 A (3P + N + PE) plug and its matching fixed socket, ensuring both are in intact, unused condition and meet basic application requirements.
• Fully insert the plug into the socket in accordance with the intended use to achieve a secure and proper connection.
• Fix the socket firmly on a stable test platform to avoid displacement or movement during the force application process.
• Attach the gauge to the plug correctly, ensuring alignment with the direction of force application specified by the standard.
• Apply a gradually increasing pulling force to the plug through the gauge, maintaining a uniform and steady force application rate.
