Product Description

Overview

The LMCK-50 1000/5A Accuracy Class 0.5 is a high-capacity, high-accuracy split-core (clamp-on) current transformer designed for demanding electrical measurement applications. With a primary current rating of 1000 A AC and a secondary output of 5 A, this CT delivers precise measurements (±0.5%) under rated conditions. Featuring a ~50 mm aperture, it accommodates large conductors or busbars, making it suitable for industrial, large commercial and energy metering settings.

Key Features

  • Primary Current: 1000 A AC 

  • Secondary Current: 5 A AC 

  • Accuracy Class: 0.5 (±0.5%) — high precision under rated conditions 

  • Model / Series: LMCK-50 — part of Zhikai’s split core (clamp-on) LMCK line with large aperture (≈50 mm) 

  • Housing & Build: Flame-retardant plastic, moisture protected; stable under normal operating conditions. Designed for durability and safe installation. 

  • Clamp / Split-Core Design: Self-locking clamp type; allows installation without disconnecting the conductor.

Technical Specifications (Typical / Expected)

Spec Value / Notes
Ratio (Primary : Secondary) 1000:5 A
Aperture / Window Diameter Approx. 50 mm (LMCK-50 model) 
Accuracy Class 0.5 (±0.5%) at or near rated current 
Frequency Typically 50 / 60 Hz (standard for LMCK series) 
Housing Material Flame-retardant plastic; adequate insulation, moisture protection 
Operating Temperature (To be confirmed with supplier) — typical ranges for similar CTs are approx. -25°C to +60°C or more.
Burden / Rated VA Load (Supplier datasheet required) — likely to be several VA (depending on secondary load and cabling)
Standards / Safety Designed to meet safety and measurement standards; ensure proper insulation, avoid open secondary under load etc.

Applications

  • Energy metering & billing systems, especially in industrial plants or large installations

  • Monitoring of heavy loads: large motors, transformer feeds, busbars, service mains

  • Retrofitting into existing wiring without interruption (clamp-on style)

  • Use with power analyzers, monitoring equipment, building management systems

Installation & Safety Notes

  • Make sure the conductor or busbar fits through the ~50 mm aperture without strain or bending of insulation

  • Always connect the secondary side to a measurement device or load (i.e. never leave secondary open while primary is energized)

  • Mount clamp securely and ensure full closure / locking for accuracy & safety

  • Avoid installing in environments with excessive moisture, strong magnetic interference, or temperatures beyond spec

  • Follow applicable electrical codes and safety standards

Benefits

  • High precision (Class 0.5) reduces measurement error — supports accurate energy tracking and billing

  • Large aperture makes it practical for high current conductors or heavy installations

  • Clamp-on design allows for easier installation and retrofitting without system shutdown

  • Durable build with protective housing reduces maintenance cost
