2556040000

Overview

The Weidmüller 2556040000 is a current sense transformer designed for industrial applications. It features a primary current rating of 40 A and a secondary current rating of 1 A, operating at 50 Hz. The unit has a power rating of 0.3 VA and a tolerance class of 1. It is engineered for DIN rail mounting with dimensions of 27.5 mm in width and 46.5 mm in height. The device operates within a temperature range of -5 °C to +50 °C.

Feature Summary

Designed for accurate current sensing in industrial environments
Supports standard DIN rail mounting for panel integration
Provides galvanic isolation between primary and secondary circuits

Applications

Industrial current monitoring systems
Electrical protection relay inputs
Energy metering equipment

Procurement Notes

Verify the specific datasheet version for the 2556040000 part number to confirm mechanical dimensions and electrical tolerances match your system requirements. Ensure the mounting rail type is compatible with the DIN rail specification. Cross-reference the primary and secondary current ratings with your circuit design to ensure proper signal scaling and accuracy class compliance.

Selection Notes

Select this component when a compact, DIN-rail mountable current transformer is required for 40 A primary circuits. The 1 A secondary output is suitable for standard industrial measurement devices. Consider the 0.3 VA burden capability and tolerance class 1 accuracy for precision applications. Verify environmental temperature limits align with the installation site conditions.

Part Context

This part belongs to the Weidmüller current transformer series, specifically tailored for industrial control panels. It serves as a critical interface for converting high primary currents into measurable secondary signals. The product line emphasizes reliability and ease of installation in standard electrical enclosures using common mounting hardware.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer catalogs for equivalent models with matching 40 A primary, 1 A secondary, and DIN rail specifications.
