TOROIDAL CORE TRANSFORMER CT MAGNETIC INTERFERENCE BWCT-725T

Details description

TOROIDAL CORE TRANSFORMER CT MAGNETIC INTERFERENCE

BWCT-725T


l Mainly used in single phase or three phase electronic energy meter, serving as current sampling tool or the current measuring tool for general industrial instruments and measuring control equipment.

l The secondary coil and magnetic core adopt vacuum epoxy sealed package, excellent waterproof and anti-seismic performance and also has good insulating property.


l The primary coil can use copper bar or copper wire for connection.


l Accuracy class can be chose: 0.1 class, 0.05 class.


l Anti magnetic interface. It satisfies the relative requirement of IEC61036 Energy Meter Standard.

Note: Wire length and colors can be customized.
