The KCISE CTK-16 Split Core Current Transformer is a high-precision AC Current Sensor designed for current measurement and monitoring in renovation projects. With a unique 45mm hole size and split core design, it enables tool-free installation without disconnecting existing cables—ideal for upgrading electrical systems in factories, commercial buildings, and residential areas. Supporting multiple current ratios (e.g., 100/5A, 200/5A) and RS485 data transmission, this transformer provides accurate current data for energy management, load monitoring, and equipment protection, making it a key component for smart electrical monitoring systems.
Split Core Design: Open the core, clamp it around the cable, and lock it—no need to cut or disconnect cables, reducing renovation time by 50% compared to traditional current transformers.
45mm Large Hole Size: Accommodates cables with an outer diameter of up to Φ16mm (for CTK-16), compatible with most single-phase electrical cables in residential and commercial scenarios.
Lightweight & Compact: Small size (54.43×45.8×66.7mm for CTK-16) allows installation in narrow electrical boxes or tight spaces.
Class 1 Accuracy: Ensures measurement errors within ±1%, meeting strict industrial and commercial accuracy requirements for energy metering and load analysis.
Multiple Current Ratios: Supports ratios like 100/5A, 200/5A, 250/5A, and 300/5A (for CTK-16), adaptable to different current ranges (150-300A input).
Stable AC Signal Output: Provides a standard 5A output (or 0.333V for specific models) for easy connection to meters, PLCs, or smart monitoring systems.
RS485 Communication: Enables long-distance (up to 1000m) stable data transmission, suitable for large-scale projects (e.g., factory workshops, commercial buildings).
Single-Phase Monitoring Optimization: Tailored for single-phase electrical systems, perfectly matching smart meters, smart circuit breakers, and energy management platforms (e.g., Tuya IoT cloud).
Wide Temperature Adaptability: Works in -20℃ to 60℃ environments, maintaining accuracy even in harsh industrial conditions.

Customized Ratio Options: Provide non-standard current ratios (e.g., 75/5A, 400/5A) based on customer project needs (minimum order quantity applies).
Installation Guidance: Offer detailed installation manuals, video tutorials, and online support to ensure correct clamping and wiring.
Quality Certification: Complies with international electrical standards, ensuring reliability for industrial and commercial use.
Bulk Order Discounts: Provide preferential prices for large orders (e.g., renovation projects, factory upgrades) to reduce customer costs.
After-Sales Calibration: Offer free calibration services within 1 year of purchase to maintain measurement accuracy.
No, it is a passive device—obtains energy from the measured current, no external power supply needed, simplifying wiring.
The CTK-16 is designed for single-phase monitoring. For three-phase systems, we recommend using 3 units (one per phase) or our CTK-36 model (for 300-600A three-phase current).
Connect the output to a standard ammeter. Compare the measured current (from the transformer) with the actual load current—errors within ±1% indicate normal operation.
