2420920000

Overview

The Weidmüller 2420920000 is a CMA-31-400-5A-5VA-1 current transformer designed for precise measurement of load current consumption using RMS value methods. It features a rated primary current of 400 A and a secondary output of 5 A, with a maximum operating voltage of 400 VDC. The device supports a rated residual current of 400 mA and operates within a temperature range of -25°C to +70°C. Measuring 52 mm in length, it utilizes a terminal block termination style and is intended for DIN rail mounting in industrial monitoring applications.

Feature Summary

Enables precise current consumption measurement via RMS value calculation
Supports high-current sensing up to 400 A primary rating
Designed for integration into industrial monitoring systems

Applications

Industrial monitoring systems requiring accurate current data
Load current consumption measurement in automation setups
DIN rail mounted electrical distribution panels

Procurement Notes

Verify the specific datasheet version (CMA-31 series) to confirm terminal block compatibility and insulation ratings. Ensure the application environment stays within the specified -25°C to +70°C operational range. Confirm that the 400 VDC maximum operating voltage aligns with the system's electrical design requirements before procurement.

Selection Notes

Select this component when a 400 A primary current rating and 5 A secondary output are required for RMS-based monitoring. Consider the 52 mm form factor for DIN rail space constraints. Validate that the terminal block termination style matches existing wiring infrastructure and that the 400 mA residual current capability meets safety standards.

Part Context

This part belongs to the CMA-31 series of current transformers from Weidmüller, engineered for industrial-grade performance. It complements other models like 2420980000 by offering a standardized 5 A output for consistent interfacing with downstream measurement devices and control systems in heavy-duty environments.
