Current Transformers

Safely monitor high currents without inserting a measuring instrument in the load circuit. These transformers contain only a secondary winding, which surrounds a load-carrying conductor (acting as the primary) and generates a smaller current that is proportional to the load current. The smaller current can be measured by a standard ammeter (sold separately) for monitoring purposes, or can open an overload relay to protect the equipment if the load current exceeds a certain value.
