Factory wholesale 220v 12v Transformer - EI41 Vertical Low Frequency Lead Transformer Lamination Silicon Steel Sheet AC Transformer – Sanhe
Factory wholesale 220v 12v Transformer - EI41 Vertical Low Frequency Lead Transformer Lamination Silicon Steel Sheet AC Transformer – Sanhe Detail:
Introduction
SANHE-EI41 needs to be installed in the automatic switch of the distribution curcuit, and is connected with the three-phase circuit inside the automatic switch to monitor the grounding signal for necessary protection. When numerical signal and phase exceeds the standard range, this transformer will cooperate with the automatic switch to implement protection actions to prevent danger happening.
