2753210000

Overview

The Weidmüller 2753210000 is a split-core current transformer designed for precise measurement of connected load current consumption using RMS value methods. It features an asymmetrical cable feed-through and free-hanging installation style. The device supports a primary current rating of 800 A with a secondary current output of 1 A. Rated power is 2.5 VA, and it maintains a tolerance class of 0.5. Operating temperature ranges from -5 °C to +50 °C. Physical dimensions include a height of 96 mm, length of 69 mm, and width of 67 mm.

Feature Summary

• Split-core design enabling non-intrusive installation around existing conductors
• Asymmetrical cable feed-through for space-saving integration
• RMS value measurement method ensures accurate current consumption monitoring

Applications

• Precise measurement of electrical load current consumption
• Industrial energy monitoring systems
• Power distribution network analysis

Procurement Notes

Verify the specific order number 2753210000 against manufacturer documentation to confirm compatibility with required primary current ratings and burden specifications. Ensure environmental conditions remain within the specified operating temperature range of -5 °C to +50 °C during deployment. Confirm that the asymmetrical cable feed-through accommodates the target conductor size for proper mechanical fit and electrical isolation.

Selection Notes

Select this component when high-accuracy RMS measurement is required for high-current applications up to 800 A. The split-core architecture facilitates retrofitting into existing electrical infrastructure without disconnecting main conductors. Consider the 2.5 VA rated power and 0.5 tolerance class to ensure compatibility with downstream metering or control devices requiring stable signal input under varying load conditions.

Part Context

This model belongs to the KCMA series of industrial current transformers manufactured by Weidmüller. These devices are engineered for robust performance in demanding electrical environments. The split-core configuration distinguishes them from solid-core alternatives, offering flexibility for installations where permanent circuit interruption is impractical or unsafe.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify exact dimensional constraints and electrical characteristics before considering alternative models from other manufacturers to ensure functional equivalence.
