Compatibility & Replacements
The Siemens 180SHT 25-131-044-001 is a direct replacement for identical units in existing installations. When specifying replacement or additional CTs, verify the ratio (100:5A), voltage rating (600V), and frequency compatibility (50–400 Hz) with your metering or protection scheme. Other Siemens 180SHT variants with different ratios (such as 150:5A, 200:5A, or 600:5A models) are available for different application requirements; consult with your controls integrator or switchgear designer to confirm the correct transformation ratio for your circuit. Current transformers must be selected to avoid saturation and ensure accurate relay operation and metering integrity.
