Product details
The CTK series of clamp current transformers uses a switchable silicon steel core or an ultra-microcrystalline core, wound with pure copper enameled wire, and the shell is made of PC or nylon engineering plastic. They are easy to install, have good linearity. Open-core current transformers play an irreplaceable role in electricity monitoring, industrial automation, and energy management due to their convenient installation and flexible use. With the development of smart grids and Industry 4.0, the demand for electrical parameter monitoring will continue to grow.
Product parameters
Main feature description
Primary current 5A-500A, secondary current 1mA-5A, inner diameter 10-50mm, accuracy class 0.5-2.
The iron core used undergoes high-vacuum heat treatment, resulting in excellent performance, stable accuracy, and high sensitivity.
The outer shell is made of high-toughness, flame-retardant PA66 material, possessing good anti-aging properties and an attractive design.
The clamp-on opening structure facilitates installation.

Product Application
Clamp current transformers (split core current transformers) are widely used in low-voltage power distribution system upgrades, smart grid construction, and energy consumption monitoring of various equipment due to their advantages of not requiring dismantling of the primary busbar, allowing for live installation, and ease of operation. They are primarily used in energy-saving retrofits for large enterprises, urban/rural power grid upgrades, data center monitoring, intelligent distribution areas, and power consumption monitoring of environmental protection equipment.
