Folding current transformer SC1 080/5A 0.7VA Class 3. Folding current transformer for easy cable conversion with the option of mounting on the top hat rail, mounting plate or fastening option with a clamping mechanism directly on the conductor. The transformer can be easily short-circuited and thus secured in the mounted state using an enclosed short-circuit bridge and the appropriate terminal point. This means that no dangerous voltage can occur on the open secondary circuit and damage to measuring devices, the transformer itself and personal injury are excluded.
