Product Description
Overview
The LMCK-24 200/5A Accuracy Class 1 is a clamp-on (split-core) current transformer from the LMCK series, designed for accurate measurement of alternating current (AC) in electrical circuits. With a primary rating of 200 A and secondary of 5 A, this CT provides reliable current monitoring for industrial, commercial, or residential systems where a Class 1 accuracy is required.
Key Features
-
Model: LMCK-24
-
Primary Current Rating: 200 A AC
-
Secondary Current Rating: 5 A AC — giving a ratio of 200:5
-
Accuracy Class: 1.0 — meaning it will have a maximum permissible error of ±1% under rated conditions
-
Design: Split-core / clamp-on — easy installation around existing conductors without breaking the circuit
-
Core / Opening Size: Approx. 24 mm inner aperture (same “24” in LMCK-24 series suggests ~24 mm window) based on similar models from LMCK split-core CT line.
-
Housing: Flame-retardant plastic, moisture-protected, stable in performance, requires minimal maintenance.
-
Self-locking clamp: Facilitates safe, secure installation; portable and suitable for retrofits.
Technical Specifications

| Safety Notes | Secondary must not be open circuit when primary energized; ensure proper insulation and mounting |
Applications
-
Energy monitoring and metering in switchboards, panels, and distribution boards
-
Retrofitting or adding measurement to existing circuits without power interruption
-
Use with power meters, PLCs, monitoring & control systems, SCADA systems
-
Monitoring of motors, lighting, HVAC, and other electrical loads where accuracy class 1 is sufficient
Installation & Safety Guidelines
-
Verify that conductor fits comfortably through ~24 mm opening; avoid forcing or bending conductor unnaturally
-
Always ensure secondary is terminated (connected to meter / load); never leave secondary open during operation—this can lead to dangerous overvoltage and damage
-
Mount securely; close and lock clamp completely
-
Avoid installing in high ambient temperature beyond spec, very humid or corrosive environments (unless rated)
-
Use proper wire / cable protection at the entry points to avoid wear
Benefits
-
Non-intrusive installation saves labour and risk (no disconnection needed)
-
Class-1 accuracy gives reliable readings for general metering / billing where higher precision isn’t necessary
-
Durable, low maintenance, consistent performance
-
Widely compatible with standard measurement devices
