Split core current transformer LMZK3-10 series
LMZK series split-core current transformers are suitable for the current measurement and microcomputer protection below 10kV circuit on AC power systems. This current transformer has many advantages: packed size, small weight, openable and easy installation, etc. They have been widely used in all-insulation loop-network switch cabinets. It can be clamped on the connected cables simply and rapidly. They have been widely used in many all-insulation loop-network switch cabinets such as ABB-Safe Ring/SafePlus, Schneider RM6/SM6, EATON SVS, Germany GA/GE, France FB, and Korea SS.
This current transformer adopted high-quality silicon steel sheet with high permeability magnetic material, which have features such as divisible iron core and small magnetic circuit loss. High-quality epoxy resin pouring in the plastic casing is adopted by semicircle ring core and secondary winding, which is moisture-resistant with stable performance.
The two-circular rings were clamped on the spilt-phase cables tightly by hoops, Integrated with the cables, have a delicate appearance.
(Note: current transformers with different specifications and parameters can be customized according to your requirements.)
