Overview
The Weidmüller 2680210000 is a CMA-41 series industrial current transformer designed for precise RMS-based load current measurement. It features a primary current rating of 1 kA and a secondary output of 5 A. The device supports a maximum burden load of 5 VA with an accuracy class of 0.5. Operating at 50 Hz, this closed-core unit is engineered for DIN rail mounting in industrial environments to facilitate accurate monitoring of high-current AC circuits.
Feature Summary
- Closed-core design for precise RMS current measurement
- DIN rail mounting configuration for industrial integration
- High primary current capacity up to 1 kA
Applications
- Industrial power distribution monitoring
- Load current consumption measurement systems
- High-power industrial circuit protection interfaces
Procurement Notes
Verify the specific ordering suffix against official Weidmüller documentation to ensure compatibility with required accuracy classes and burden ratings. Confirm that the 5 VA load limit aligns with downstream instrument requirements. Check for any regional certification marks necessary for your specific installation environment before finalizing procurement.
Selection Notes
Select this component when primary currents reach 1 kA and a standard 5 A secondary output is required. Ensure the connected measuring instruments do not exceed the 5 VA burden rating. Verify that the 50 Hz operating frequency matches the system's electrical characteristics. Consider the DIN rail form factor for panel space constraints.
Part Context
This model belongs to the CMA-41 series of compact low-power current transformers from Weidmüller. The series focuses on converting high AC currents into standardized secondary signals for industrial sensing applications. It complements lower-rated variants within the same product family designed for currents up to 600 A.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Consult official manufacturer cross-reference lists for verified alternatives.
