Product Description

Overview

The LMCK-24 100/5A Accuracy Class 1.3 is a split-core (clamp-on) current transformer designed for easy, safe measurement of AC current in a live conductor without the need to disconnect wiring. With a primary current rating of 100 A and a secondary output of 5 A, this CT is suitable for energy monitoring, protection and measurement functions in industrial, commercial, or residential electrical systems.

Key Features

  • Model: LMCK-24

  • Primary Current: 100 A AC

  • Secondary Current: 5 A AC — ratio 100:5

  • Accuracy Class: 1.3 (C1.3), meaning ±1.3% error under specified conditions

  • Type: Split-core / clamp-on transformer — allows installation around conductors without having to break the circuit

  • Window/Core opening size: (if same as LMCK-24 standard) ~24 mm inner diameter (depends on variant) — large enough for many typical cable sizes. 

  • Housing: Flame retardant plastic, moisture protected; stable performance, minimal maintenance required. 

  • Self-locking clamp mechanism: Easy and safe installation around conductors. 

Technical Specifications

Specification Detail
Primary current rating 100 A AC
Secondary current rating 5 A AC
Transformation ratio 100:5
Accuracy class 1.3 (Class C1.3)
Core / window size ~24 mm opening (depending on exact LMCK-24 version)
Housing / Enclosure Flame-retardant plastic; moisture protected; self-locking clamp design 
Burden (max load on secondary) To be specified by manufacturer or in datasheet
Safety / insulation Plastic case conforms to standard requirements; safe handling recommended; secondary must not be left open circuit when primary is energized 
Operating temperature / environmental limits To be specified by the manufacturer (e.g. −20°C to +70°C etc.)

Applications

  • Energy and power monitoring in switchboards, panels, and distribution boards

  • Feed into meters or monitoring devices (PLCs, SCADA, power analyzers)

  • Retrofitting existing circuits where opening the primary conductor is inconvenient

  • General protection, current over-load detection, load balancing

Installation & Use Notes

  • Ensure the conductor to be measured fits through the clamp opening comfortably without deformation.

  • Do not open the secondary circuit when the primary is energized. Always connect the secondary to a load (meter, burden resistor, etc.) to avoid dangerous voltages.

  • Mount the CT securely; ensure clamp is fully closed and locked.

  • Minimize external magnetic interference: avoid placing near large magnetic fields or heavy electromagnetic equipment unless shielded.

  • Ensure compliance with local electrical codes and standards.

Benefits

  • Non-intrusive installation reduces downtime and labour cost

  • Reliable measurements thanks to accuracy class 1.3

  • Durable build, minimal maintenance needed

  • Suitable for many standard measurement tasks
