Product Description

Overview

The LMHK-612 (60×120 mm) 2500/5A Accuracy Class 0.5 is a high-precision, open / clamp-on (split-core) current transformer designed for heavy-duty electrical monitoring applications. With a massive primary current rating of 2500 A AC and a standard 5 A secondary output, this CT provides ±0.5% accuracy under rated conditions. The large window (≈ 60×120 mm) allows it to accommodate large busbars or multiple conductors, making it ideal for industrial, commercial, or utility electrical panels.

Key Features

  • Model / Series: LMHK-612

  • Primary Current Rating (In): 2500 A AC

  • Secondary Current Rating (Is): 5 A AC — transformation ratio 2500:5

  • Accuracy Class: 0.5 (Class 0.5) — high fidelity measurements suitable for billing, monitoring, and power quality tasks

  • Window / Aperture Size: ~ 60×120 mm — this large opening is suitable for thick busbars or bundled conductors

  • Design: Split-core / clamp-on style, allowing installation without breaking existing conductors

  • Housing & Materials: Flame-retardant plastic casing, moisture protection, durable core material; designed for stable performance and low maintenance

Technical Specifications (Typical / Expected)

Specification Value or Comments
Primary : Secondary Ratio 2500 : 5 A
Accuracy Class 0.5 (±0.5%) under rated burden
Window Aperture Approx. 60 mm × 120 mm
Rated Frequency 50 / 60 Hz (verify with manufacturer)
Maximum Burden (VA) Usually in the order of 10-15 VA for transformers of this size and accuracy; must be confirmed
Insulation / Dielectric Strength High insulation, likely several kV for test rating; case designed to meet safety standards
Operating / Ambient Temperature Expected −25 °C to +75 °C (verify)
Mounting / Installation Clamp / split-core type; ensure good mechanical fit and locking; secure mounting essential

Applications

  • Industrial switchgear and distribution boards with high current busbars

  • Utility metering / energy management in big commercial installations

  • Accurate power monitoring, billing, and power quality measurement where high currents are involved

  • Retrofit or upgrade jobs where the existing equipment or busbars cannot be dismantled

Installation & Safety Notes

  • Ensure the conductors or busbars fit cleanly through the large aperture without causing damage to insulation

  • Always connect the secondary winding to a measuring instrument or burden resistor; never leave secondary open when primary is energized — this can cause dangerous voltages

  • Clamp must be fully closed, locked, and mechanically secure for accurate performance and safety

  • Avoid placing near strong external magnetic or electromagnetic interference sources

  • Protect the unit from environmental extremes (humidity, dust, high temperature) beyond its rated limits

  • Adhere to local electrical codes, wiring, grounding, and insulation standards

Benefits

  • Very high current capacity (2500 A) in a compact design for large aperture systems

  • Excellent measurement accuracy (0.5%) — suitable for critical monitoring and billing applications

  • Clamp-on / split-core design for easier installation / retrofitting without service interruption

  • Durable design with safety minded features
