Dimensions - 159 x 154.5 x 39 mm Primary bar - 4 x 80 x 10 mm Round conductor - ⌀ 80 mm Application Split core current transformers convert an alternating current of high value into a proportional, lower one, which is appropiate to be measured by standard instruments (ammeters, wattmeters, varmeters, power factor meters, relays, measuring transducers...) of rated currents 5 or 1 A. Their split core allows their installation in already existing networks without need to cut the conductors. They are suitable for indoor use in low-voltage networks, and they are built according to IEC and EN 61869-2 standards. Design features - The current transformers can be opened - Cases of self-extinguishing polycarbonate UL 94 - V0 - Double secondary terminals, for short circuiting the secondary winding before opening the measuring circuit - Mounting brackets for the panel mounting and fixing clamps for the fixing to the primary bus bar are included Accuracy Our current transformers fulfil the specifications of the accuracy classes 0.5, 1 and 3, for the rated burden indicated in the table, in the same instrument
