VDE 0620-1 Lehre 19b Shutter Force Test Gauge for 2.5A 250V Outlets

The VDE 0620-1 Lehre 19b Shutter Force Test Gauge for 2.5A 250V Outlets is engineered to measure the force required to open protective shutters on 2.5A 250V electrical outlets, ensuring strict compliance with VDE 0620-1 Lehre 19b, DIN 49440-2, and DIN 49437 standards. This precision instrument incorporates a movable design that enables full insertion under its own weight, with exact dimensional control and stable operational characteristics to deliver accurate and repeatable force measurements for outlet shutter compliance verification.

Specifications:
• Applicable standards: VDE 0620-1 Lehre 19b, DIN 49440-2, DIN 49437
• Rated parameters: 2.5 A, 250 V
• Core function: Testing the force required to open outlet shutters
• Key dimensions: 26.1 ± 0.5 (unit unspecified, per standard), R5.5 ± 0.1, 13.7 ± 0.7
• Design feature: Movable structure, fully insertable by its own weight
• Dimension adjustment: Allowable extension of dimension “a” up to 115.0 if the shutter cannot be fully opened (per standard provisions)
• Manufacturing requirement: Strictly fabricated in accordance with VDE 0620-1:2010 relevant specifications
• Compliance scope: Aligns with standard clauses 10.5 and 21 of DIN 49440-2 and DIN 49437

Test Procedures:
• Inspect the gauge for cleanliness, no visible damage, and confirm its movable structure operates smoothly before use.
• Secure the 2.5 A, 250 V outlet under test in a stable, horizontal fixture to prevent position deviation.
• Align the gauge with the outlet’s shutter opening position as specified in VDE 0620-1 Lehre 19b.
• Allow the gauge to insert fully into the outlet by its own weight without applying additional external force.
• Measure and record the force required to open the outlet shutter during the insertion process.
