Product Description

Overview

The LMHK-58 (50×80 mm) 1600/5A Accuracy Class 0.5 current transformer is a precision, open/clamp-on (split‐core) transformer designed for monitoring high currents in power systems. With a large aperture of approx. 50×80 mm, and a ratio of 1600 A primary to 5 A secondary, it delivers accurate measurement (±0.5%) suitable for demanding metering, protection, or power monitoring tasks.


Key Features

  • Model / Series: HK-58 (LMHK-58) split-core type with clamp/open design

  • Primary Current Rating: 1600 A AC 

  • Secondary Current Rating: 5 A AC 

  • Accuracy Class: 0.5 (±0.5%) under rated load, for precision metering tasks 

  • Window / Aperture Size: Approx. 50×80 mm to accommodate large conductors or busbars 

  • Type: Split-core, clamp/open style – allows installation without disconnecting the primary conductor 

  • Housing Material: Flame retardant plastic case, moisture resistant; built for stable performance in harsh industrial settings 


Technical Specifications (Typical / Expected)

Specification Detail / Expected Value
Ratio (Primary : Secondary) 1600 : 5 A
Accuracy Class 0.5 (±0.5%) 
Aperture / Window Size ~ 50×80 mm (busbar / cable space) 
Rated Frequency 50-60 Hz (usually) 
Burden / Secondary Load Typical VA rating for HK-58 at 1600/5A, class 0.5 often ~10 VA — check datasheet 
Operating Temperature Approx. -25 °C to +75 °C, industrial rating
Insulation / Dielectric Strength Usually meets standards (PC/UL94-V0 case, insulation resistance, etc.) 
Mechanical Type Clamp / split core with self-locking mechanism, large window for bus-bars or thick conductors

Applications

  • Industrial / commercial power metering, energy management systems

  • Monitoring high-load circuits: large motors, transformer feeders, busbars

  • Protection systems where accurate current measurement is required

  • Retrofit applications: open design allows installation without circuit interruption

  • Integration with power analyzers, SCADA, building management systems


Installation & Safety Instructions

  • Ensure the conductor or busbar to be measured fits nicely through the 50×80 mm opening, without strain or deformation.

  • Never leave the secondary open when the primary is energized — always connect a proper measurement device or load (meter / burden) to avoid dangerous voltages.

  • Secure the clamp fully; ensure locking mechanism engaged, stable mounting.

  • Avoid placing near strong external magnetic fields or in environments above the maximum rated temperature / moisture.

  • Comply with local electrical standards and safety codes.


Benefits

  • High accuracy (0.5%) improves measurement reliability, especially for billing, power quality, audits.

  • Large aperture allows for thick cables or busbars without requiring modifications.

  • Split-core/clamp design easing installation and reducing system downtime.

  • Durable materials and housing reduce maintenance and prolong lifespan.
