Folding current transformer SC2 500/5A 2.2VA Class 1. Folding current transformer for easy cable conversion with the option of mounting on the top hat rail, mounting plate or fastening with a clamping mechanism directly on the conductor. The converter can be easily short-circuited and thus secured in the mounted state using an enclosed short-circuit bridge and the appropriate terminal point. As a result, no dangerous voltage can occur on the open secondary circuit and damage to measuring devices, the converter itself and also personal injury are excluded.
