Description
Single-phase transformers with standard EI shape lamination with welded core are produced in accordance with ČSN EN 61 558 in any voltage transfer combination between 1 V and 1 000 V, frequency 50/60 Hz, covering IP00, terminals IP20, insulation class B and a maximum ambient temperature of 40°C. Their sizes and rated outputs are shown in the table. Optional changes to the design include protective shielding, higher insulation class, higher ambient temperature, primary or secondary winding protection, or the addition of thermal fuses.
SR– welded core, transformer terminal block
SL – welded core, feed-through terminal block for mounting on TS 35 rail. For currents above 60 A.
