Product Description

30KVA Three Phase Voltage Transformer 380V To 220V Over Current Protection


1. Product Overview



The transformer introduced here is a 30KVA three phase transformer, with input voltage 380V and output voltage 220V. The rated capacity of three phase transformer ranges from 500VA to 1000KVA. It could be tailored according to your needs. Also, the primary and secondary voltage could be customized according to your request.


This transformer is designed with an enclosure and an over-current protection switch. When the rated current it over the rated one, the protection switch would react and trip to get the transformer stop working. If it trips, it gives out signal to you that the load is over the rated capcity. So you could adjust the load and restart the load equipment and transformer again.
