2656290000

Overview

The Weidmüller 2656290000, model KCMA-RCM-812D, is a split-core residual current transformer designed for precise load current consumption measurement using RMS value methods. It features a primary current rating of 18 A and a secondary current rating of 40 mA. The device accommodates round conductors with a maximum diameter of 80.00 mm. This component supports energy monitoring applications within industrial automation systems.

Feature Summary

• Split-core design enables installation around existing conductors without circuit interruption
• Utilizes RMS value methods for accurate current consumption measurement
• Supports large round conductor diameters up to 80.00 mm

Applications

• Energy monitoring in industrial automation systems
• Residual current measurement for load analysis
• Integration into smart metering infrastructure

Procurement Notes

Verify the specific ordering suffix matches the required technical specifications before purchase. Confirm that the primary current rating of 18 A aligns with the target application's electrical requirements. Ensure the split-core mechanism is compatible with the conductor size of 80.00 mm. Cross-reference the manufacturer part number 2656290000 with official catalogs to validate availability and compliance status.

Selection Notes

Select this component when RMS-based residual current measurement is required for loads up to 18 A. The split-core architecture is essential for retrofits or installations where breaking the primary circuit is not feasible. Consider the 80.00 mm conductor clearance requirement when designing enclosure layouts. Evaluate compatibility with downstream signal processing equipment accepting 40 mA secondary outputs.

Part Context

This component belongs to the KCMA series of current transformers from Weidmüller. It serves as a specialized sensor for industrial connectivity solutions, bridging power distribution monitoring with data acquisition systems. The product supports the company's focus on intelligent measurement systems and IoT-ready automation technologies.

Replacement Considerations

The similar product 2656280000 (KCMA-RCM-58D) offers comparable functionality but differs in conductor diameter capacity. Verify if the reduced clearance of the alternative model meets the physical constraints of the installation environment before substitution.
