The AB 500-3A (Abwurfbehälter) was a cluster bomb used by the Luftwaffe during World War II.

In the center of the beam, there was an adjustable circular metallic band that was divided into two U-shaped sections.

There was a vertical bulkhead which ran through the center of the beam and the adjustable band which housed a rectangular compartment that housed the cables needed for arming the Rheinmetall electric fuzes used by the German SD series of bombs.

The German's captured large amounts of ordnance after the Fall of France and put these to use.

It is possible to narrow down the models of French bombs used from TM 9-1985-6, French and Italian Explosive Ordnance because not all of the 50kg and 100kg bombs were nose fuzed and the AB 500-3A had an arming system for mechanical nose fuzes.
