Overview
The Weidmüller 2680220000 is a closed current sense transformer designed for precise measurement of load current consumption using RMS value methods. It features an asymmetrical cable feed-through and is intended for DIN rail mounting. The device operates at 50Hz with a primary current rating of 1.25 kA (1250 A) and a secondary current rating of 5 A. It supports a maximum burden of 5 VA and maintains a tolerance class suitable for industrial applications.
Feature Summary
- Provides precise current consumption measurement via RMS value methods
- Features an asymmetrical cable feed-through design for installation flexibility
- Constructed as a closed current transformer for secure signal acquisition
Applications
- Industrial current monitoring systems
- Energy management and power distribution panels
- Load analysis in electrical infrastructure
Procurement Notes
Verify the specific datasheet version to confirm technical compliance, as product representations may vary. Ensure the application environment matches the 50Hz operational frequency and 1.25 kA primary current rating. Confirm that the required secondary burden does not exceed 5 VA to maintain accuracy. Check for RoHS compliance details if environmental regulations apply to the project scope.
Selection Notes
Select this component when a closed-loop current transformer is required for high-current industrial measurements up to 1.25 kA. The asymmetrical feed-through design offers installation advantages over symmetrical alternatives in constrained spaces. Ensure the system interface accepts a 5 A secondary output and can handle the specified 5 VA burden without degradation of measurement precision.
Part Context
This model belongs to the CMA series of current transformers from Weidmüller, specifically engineered for industrial environments. The part number 2680220000 corresponds to the CMA-51-1250-5A-5VA-0,5 configuration, indicating its specific current ratings and burden capacity within the manufacturer's portfolio of precision measurement modules.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official Weidmüller catalogs for direct replacements or cross-references based on identical primary/secondary ratings and mechanical constraints.
