Description
Overview
The LMCK-24 300/5A Accuracy Class 1 is a high-rating split-core (clamp-on) current transformer, designed for precise AC current measurement. With a primary rating of 300 A and secondary of 5 A, this model delivers reliable and accurate readings (±1%) under standard operational conditions. It's ideal for retrofits and new installations where the wiring can’t be disrupted.
Key Features
-
Primary Current: 300 A AC
-
Secondary Current: 5 A AC (output) — transformation ratio 300:5 A
-
Accuracy Class: 1.0 (±1%) under rated conditions / on standard burden
-
Window / Inner Diameter: ~24 mm, suitable for many cables or busbars without tight bending or deformation limits.
-
Type: Split‐core / clamp-on — allows installation without breaking the primary conductor.
-
Housing: Flame-retardant plastic enclosure, moisture protection, stable performance; low maintenance.
-
Safety Notes: Secondary winding must not be open-circuited when primary is energized. Always use with meter or burden load.

Applications
-
Monitoring electrical load in switchboards, control panels, and distribution circuits
-
Integrating with energy meters, power analyzers, PLCs, or building management systems
-
Retrofit projects where primary conductors remain energized
-
Use in industrial, commercial, or large residential installations
Installation & Safety Notes
-
Make sure the conductor or busbar fits cleanly into the ~24 mm window without deformation.
-
Never leave the secondary side open circuit when primary is carrying current — always connect to meter or burden load.
-
Secure the clamp / split core properly; ensure good mechanical fit.
-
Avoid placing near sources of strong magnetic interference.
-
Follow local electrical safety / grounding codes.
Benefits
-
Accurate (Class 1) readings for many measurement use cases
-
Non-intrusive installation saves time — no need to disconnect the primary circuit
-
Durable, stable, with low maintenance
-
Compatible with standard 5 A secondary devices
