2753170000

Overview

The Weidmüller 2753170000 is a split-core current transformer designed for industrial applications. It features a primary current rating of 400 A and a secondary current rating of 1 A. The device supports a maximum load of 2.5 VA and maintains an accuracy tolerance class of 0.5. Physical dimensions include a height of 96 mm, length of 69 mm, and width specified in documentation. Operating temperature ranges from -5 °C to +50 °C. It utilizes wire leads for termination and employs a free-hanging mounting style.

Feature Summary

• Split-core design allows installation without disconnecting the primary conductor
• Utilizes rms value methods for precise current consumption measurement
• Supports asymmetrical cable feed-through configurations

Applications

• Industrial current monitoring systems
• Energy management and power distribution analysis
• Load current measurement in electrical panels

Procurement Notes

Verify that the specific order number 2753170000 matches the required 400 A primary rating and 1 A secondary output. Confirm the 2.5 VA burden capacity aligns with connected metering or relay inputs. Ensure environmental conditions remain within the -5 °C to +50 °C operating range. Check regional availability restrictions as some distributors may report limited stock or shipping limitations for this component.

Selection Notes

Select this model when non-intrusive installation on existing busbars or cables is required. The split-core architecture facilitates retrofitting into active electrical infrastructure. Verify that the 400 A primary rating covers the maximum expected load current. Ensure the secondary circuit impedance does not exceed the 2.5 VA limit to maintain the 0.5 accuracy class. Consider the physical clearance needed for the 96 mm height and 69 mm length during panel layout.

Part Context

This component belongs to the KCMA series of industrial current transformers by Weidmüller. The series focuses on accurate AC current sensing for industrial automation and energy monitoring. The KCMA-42 variant specifically addresses higher current ratings up to 400 A while maintaining compact form factors suitable for standard electrical enclosures and switchgear applications.
