Pin-Type Zero-Sequence Current Transformer
The pin‑type zero‑sequence current transformer features pin terminals for direct PCB mounting, designed specifically for zero‑sequence current monitoring and ground fault protection in three‑phase systems. With high accuracy and low phase error, it enables real‑time current vector summation detection, making it widely applicable in power protection, fault diagnosis, and load imbalance monitoring systems.
Pin-Type Zero-Sequence Leakage Current Transformer
The pin-type zero‑sequence leakage current transformer features pin terminals for direct PCB mounting, enabling high‑sensitivity detection of ground leakage current and zero‑sequence monitoring. With excellent electrical isolation and noise immunity, it is widely used in EV charging equipment, medical devices, and industrial safety systems for ground fault protection.
Closed Zero-Sequence Current Transformer Series
Residual Current Transformer (RCT) - Solid-Core Type
Through-Hole Current Transformer is designed for cable circuit applications, featuring compact structure and flexible installation. With bore diameters ranging from 30mm to 200mm, it accommodates main circuit currents from 63A to 2000A. The product offers accuracy classes from 0.2 to 1, meeting the latest national standards for balance characteristics. Unbalanced current output can be as low as 3mA, significantly reducing false alarms caused by magnetic interference. The full series complies wit
CTKY Series Circular Split-Core Residual Current Transformer (RCT)
Features a snap-open design for tool-free installation in confined spaces. Equipped with a nanocrystalline core for high sensitivity and low temperature drift, suitable for leakage current monitoring and protection in power distribution systems, charging piles, and photovoltaic systems, with tamper-proof and moisture-resistant housing.
ZH-CTK Series Rectangular Split-Core Residual Current Transformer
Features a rectangular split-core design for easy installation without power interruption on existing busbars or cables. Equipped with a nanocrystalline core for high accuracy and low temperature drift. The housing is made of flame-retardant ABS material, suitable for residual current monitoring and fault protection in power distribution systems, charging facilities, and industrial applications.
ZH-CTK Circular Split-Core Residual Current Transformer (RCT)
Featuring a circular snap-open/snap-close structure, it supports live-line rapid installation without disassembling busbars or cables. Equipped with a high-sensitivity nanocrystalline core, full epoxy resin encapsulation, and a flame-retardant ABS housing, it is suitable for residual current monitoring and ground fault protection in photovoltaic systems, charging piles, and power distribution systems.
