Overview
The Weidmüller 2603420000 is a residual current transformer, model CMA-RCM-DACT-20. It features a primary current rating of 25 A and supports round conductors with a diameter of 2 cm. The device operates at 50 Hz and utilizes a closed current transformer design for accurate detection. It is engineered for DIN rail mounting to ensure secure installation in industrial control panels.
Feature Summary
- Highly sensitive current sensor for detecting minimal residual currents
- Fixed switching hysteresis of 5% for stable operation
- Closed current transformer design ensuring precise measurement
Applications
- Industrial residual current monitoring systems
- DIN rail mounted electrical protection circuits
- Detection of small leakage currents in AC systems
Procurement Notes
Verify the specific datasheet version for the CMA-RCM-DACT-20 series to confirm technical compliance. Ensure the application environment matches the 50 Hz operational frequency and 25 A primary current rating. Confirm that the conductor size fits within the specified 2 cm diameter requirement for proper installation and accuracy.
Selection Notes
Select this component when high sensitivity is required for residual current detection in industrial settings. The fixed 5% hysteresis provides reliable switching without unnecessary fluctuations. Ensure compatibility with existing DIN rail infrastructure and verify that the closed core design meets the specific safety standards required for the target electrical system.
