Zero Phase Current Transformer For Electrical Safety

When a current exceeding 30 mA passes through the human body the individual will be at serious risk of a fatal electric shock if the current is not interrupted in a timely manner.

Besides, with the increasing ratio of electrical fire to fire, electrical fire has badly threatened people’s life and property security.

Electrical safety devices that shuts off an electric power circuit when it detects that current is flowing along an unintended path, such as through water or a person.

Our zero phase current transformer applied on customers successful projects for EV charging device，GFCI, RCD preventing from electric shock.

Why Choose us?
