Product Description
Overview
The LMCK-36 600/5A Accuracy Class 0.5 is a high-capacity, high-precision split-core current transformer ideal for metering, monitoring, and protection in electrical systems drawing up to 600 amps. It converts a 600 A primary current to a 5 A secondary current, with ±0.5% accuracy under rated conditions. The 36 mm aperture (window) gives flexibility for larger conductors or busbars, making it suitable for demanding industrial or commercial installations.
Key Features
-
Primary Current Rating: 600 A AC
-
Secondary Current Rating: 5 A AC
-
Accuracy Class: 0.5 (±0.5%) — ensures quite precise measurements for metering and power monitoring under rated load
-
Model / Series: LMCK-36 — 36 mm inner diameter window / hole size for the conductor.
-
Design: Split-core (clamp-on) with self-locking mechanism for tool-free, non-invasive mounting
-
Housing: Flame-retardant plastic that meets isolation and safety norms; moisture-protected; stable performance with minimal maintenance.
Technical Specifications (Typical / From LMCK-36 Data)
| Specification | Typical Value / Comment |
|---|---|
| Window / Aperture Diameter | ~36 mm (inner hole size) |
| Accuracy Class | 0.5 (±0.5%) |
| Current Ratio | 600:5 A |
| Rated Frequency | 50/60 Hz (common for LMCK series) |
| Housing Material | Flame-retardant plastic, isolation per UL94-V0 etc. |
| Burden / Secondary Load | (to be confirmed with datasheet; typical values may be in the few VA range) |
| Operating Temperature Range | (manufacturer spec needed) |
| Safety / Isolation | Secondary must never be open when primary is energized; safe insulation, protective enclosure. |
Applications
-
High current panel and switchboard metering / monitoring
-
Industrial machinery, busbar systems, large HVAC units, etc.
-
Retrofit installations where existing conductors are in place and cannot be interrupted
-
Use with submeters, power analyzers, energy management systems
Installation & Safety Guidelines
-
Ensure the conductor or busbar fits through the 36 mm window without forcing or damaging insulation
-
Always connect the secondary output to a load (meter, burden resistor) — do not leave secondary open when the primary is energized
-
Clamp fully closed and locked; ensure mechanical stability
-
Avoid placing near strong external magnetic interference or extreme environmental exposure
-
Follow relevant local safety, grounding, electrical code requirements
Benefits
-
Very good measurement accuracy (0.5%) — suitable for applications where precision matters (billing, energy auditing, sensitive monitoring)
-
Non-intrusive installation — clamp-on design reduces downtime / labor costs
-
Capable of handling 600 A on primary, which works for fairly large loads
-
Durable housing, moisture protection, stable performance
