currentcast resinIEC

DESCRIPTION The adapter transformer cod.TDP010... is used, in connection with 3 or 4 current transfor- mers, to sense the differential current in case it is not possible, with a single toroid, to grip all the conductors of the system to be protected. The current transformers used (to be ordered separately) must be of the same type; for upgrading of existing systems are particulary well suited the split core transformers ( see codes TAA030..., TAA080..., TAA120..., TAA160... ) - Technical data accuracy class 0,5 self estinguishing thermoplastic material UL 94-V0 operating frequency 40 - 65Hz per reference insulation voltage 0,72 kV test voltage 3 kV x 1’ 50 Hz protection IP 20 safety factor N < 5 operating temperature -25 +50 °C storage temperature -40 +80 °C manufactured according to CEI EN,IEC VDE, BS, UTE
