Suitable for 380-416 V three-phase industrial distribution systems, providing isolated power supply for 115 V or 230 V controlled loads When selecting, it is necessary to verify the total steady-state VA, impulse VA, and power factor of the control circuit to ensure that the impulse value is ≤ the transformer's allowable short-term overload curve Due to the absence of a fuse holder (suffix -0-N) at the factory, it is necessary to install suitable capacity quick break fuses or circuit breakers on the primary and secondary sides in accordance with NEC and local regulations to achieve short-circuit protection Typical applications include machine tools, pump stations, conveyor lines, etc., which require reducing the 400V voltage level to the control voltage“
