Product Overview: Through-Hole Ring CT 0.66kV for Metering

EcoNewlink’s Through-Hole Ring CT 0.66kV for Metering is a compact ring current transformer engineered for accurate, repeatable measurement in energy meters, panelboards, and smart distribution systems. Built for metering accuracy and simple through-hole installation, this ring CT is ideal for electricians, electrical panel builders, EPC contractors, and system integrators who demand reliable current measurement without complicated wiring changes.

Key Features

  • Rated voltage: 0.66kV — compatible with low-voltage metering systems.
  • Through-hole (ring) design — fits conductor without disconnecting circuits for fast retrofit and installation.
  • High metering accuracy — optimized for energy meter integration and billing-grade measurement.
  • Robust insulation and mechanical strength — ensures safety and long-term stability.
  • Compact footprint — saves panel space and supports high-density layouts.

Benefits for Your Project

EcoNewlink Through-Hole Ring CTs reduce installation time and human error, lowering labor costs and downtime during upgrades. Their metering-grade performance ensures accurate energy data for billing, load monitoring, and power quality analysis. Because the design eliminates the need to open existing busbars or disconnect conductors, it is especially useful in live system retrofits.

Applications

Common uses include:

  • Integration with multifunction power meters and energy meters
  • Commercial and industrial electrical panels
  • Energy monitoring in buildings, factories, and microgrids
  • OEM assemblies for switchboards and distribution cabinets
