DC TOROIDAL COIL CURRENT TRANSFORMER BWCT-704/ BWCT-704D

Details description

DC TOROIDAL COIL CURRENT TRANSFORMER

BWCT-704/ BWCT-704D


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 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 D type has the DC component sensing property; DC component measure has high accuracy, which can satisfy the relative requirement of IEC61036 Energy Meter Standard.


Note: Wire length and colors can be customized.
