Overview
The Weidmüller 2603450000 is a residual current transformer designed for industrial applications, specifically identified by the order code CMA-RCM-DACT-120. It features a primary current rating of 25 A and a secondary current rating of 40 mA. The device operates at a frequency of 50 Hz and utilizes a DIN Rail mounting style. It incorporates a fixed switching hysteresis of 5% to ensure stable detection of residual currents.
Feature Summary
- Highly sensitive current sensor for detecting even the smallest residual currents
- Fixed switching hysteresis ensures stable operational performance
- Designed for precise measurement of load current consumption using rms value methods
Applications
- Detection of small residual currents in industrial systems
- Precise measurement of current consumption for connected loads
- Asymmetrical cable feed-through monitoring
Procurement Notes
Verify the specific order code CMA-RCM-DACT-120 against the manufacturer's official documentation to confirm compatibility with existing system requirements. Ensure that the 25 A primary current rating and 40 mA secondary output align with the intended circuit design before finalizing procurement decisions.
Selection Notes
Select this component when high sensitivity for residual current detection is required in industrial environments. The fixed 5% switching hysteresis provides reliable operation without excessive sensitivity to noise. Confirm that the DIN Rail mounting style fits the available panel space and that the 50 Hz frequency matches the system's power supply characteristics.
Part Context
This part belongs to the Weidmüller Current Transformers - Industrial category. It is a closed current transformer device intended for accurate load monitoring. The product is manufactured by Weidmüller and is distinct from general-purpose sensors due to its specific residual current detection capabilities and industrial-grade construction.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing control systems before considering alternative models.
