Note:
Two single-phase step transformers (in V-circuit) according to DIN EN 61558, VDE 0570, part 2-13. Common exit and entry coil. Coils without galvanic separation. Connection to cage clamps, prepared for safety class I, ta 40°C, 50/60 Hz, dip impregnated.
Options:
* These transformers are suitable as in-line transformers for electrical consumers, e.g. speed control of 3-phase ventilated motors. * 1 set consists of two single-phase transformers. * Ordering a single unit is also possible. * Wiring two single-phase transformers in V-circuit produces a three-phase system suitable for this application.
