Product Description

Overview

The LMCK-50 800/5A Accuracy Class 0.5 is a split-core (clamp-on) current transformer designed for accurate measurement of high AC currents without interrupting the primary circuit. With a primary rating of 800 A and secondary output of 5 A, and an error tolerance of ±0.5% under rated conditions, it suits precision metering and monitoring in demanding industrial, commercial or high-load applications.

Key Features

  • Model / Series: LMCK-50 (Zhikai) – part of the split-core current transformer family. 

  • Primary Rating: 800 A AC 

  • Secondary Rating: 5 A AC 

  • Accuracy Class: 0.5 (i.e., ±0.5%) — good for precision metering applications where lower error is required.

  • Window / Inner Hole Size: ~50 mm (inner diameter), matching LMCK-50 family which supports up to 50mm hole size. 

  • Housing: Flame-retardant plastic enclosure, moisture-protected, stable performance, minimal maintenance. 

  • Clamp / Split-Core Design: Self locking clamp mechanism, allowing for easy installation / retrofit without disconnecting the primary conductor. 

Technical Specifications (As Expected / Typical)

Specification Detail / Expected Value
Primary current rating (In) 800 A AC
Secondary current rating (Is) 5 A AC
Transformation ratio 800 : 5
Accuracy class 0.5 (±0.5%) at rated current
Inner diameter / window size ~50 mm 
Rated frequency 50/60 Hz (confirm supplier spec)
Housing material Flame retardant plastic; inert, moisture-protected 
Burden (maximum VA load of secondary) To be confirmed with datasheet — typical CT load specs needed
Operating temperature / environmental limits Supplier-specified; likely standard industrial ambient (e.g. -20°C to +60°C)
Safety / Insulation Plastic enclosure; secondary winding must not be open when primary is energized; isolation meets UL94-V0 for plastic case. 

Applications

  • High current load monitoring in industrial switchboards or distribution panels

  • Precision energy metering, auditing and power quality applications

  • Integration with power analyzers, PLCs, SCADA or building management systems

  • Use where the primary cable/conductor cannot be disconnected (retrofit)

Installation & Safety Notes

  • Ensure the conductor or busbar fits through the ~50 mm opening without strain, deformation, or damage to the conductor insulation.

  • The secondary circuit must always be terminated (connected to the measuring device or burden resistor); never leave the secondary circuit open while the primary is carrying current.

  • Secure the clamp fully, ensure mechanical integrity, avoid mechanical vibration affecting readings.

  • Avoid placing the CT in proximity of strong external magnetic fields that could distort readings.

  • Follow local electrical codes for grounding, insulation, enclosure, etc.

Benefits

  • ±0.5% accuracy gives high fidelity in measurements—good for billing, precision energy monitoring

  • Large aperture (~50 mm) allows for large conductors or busbars

  • Clamp-on installation means easier, safer retrofitting without interrupting operations

  • Durable construction (plastic, moisture protection) means lower maintenance
