The safety plug is opened with a Phillips screw (PH2.5 bit). Then take a SL3 bit and lifts the lateral two bracelets on easily. Now can the plug head at the contacts simply pull out of the shaft. Since not a trick with the screw is. I have uploaded to pictures in the gallery.
The plug is very well made. Inside all connections are fitted with Phillips screws. Perfect. The terminals for neutral and phase conductor ferrules to take up to 2.5 mm² (gray). For the protective conductor to own terminals in Ösenform (red). Place is in the connector enough for it and when it was crimped properly, anyway.
Little info on the edge: The to be seen in the photos screwdriver is part of the set "Jackly JK 6089-A". Therefore, the above bit sizes.
My Conclusion:
Very good plug, flawless workmanship, price spike. Who knows ABL Sursum, gets a really good product. I recommend the plug and have a look at the manufacturer's site.
