Non-short-circuit-proof safety isolating transformer
A shield containing two overlapping vertical circles with a horizontal line across their overlap and two short parallel legs hanging from the lower circle. · also called “non short-circuit-proof transformer”, “not short-circuit proof”, “safety isolating transformer”
What the Non-short-circuit-proof safety isolating transformer symbol means
Safety isolating transformer, not short-circuit-proof
Marks a safety isolating transformer that is not short-circuit-proof on its own. The two short legs under the circles distinguish it from the short-circuit-proof version, which has a small closed box there. Such a transformer depends on separate protection against overload or a short circuit on its output.
