Technical Specifications

Version & Model Difference

The Siemens 3TF series includes various versions differentiated by coil voltage, rated current, and auxiliary contact configurations. The 3TF3211-0XP0 is a specific variant with a 230V AC coil and 32A rating. Other versions in the series, such as 3TF3211-0XM0 (24V AC coil) or 3TF3211-0XP2 (with different coil voltage), offer similar performance but with different control voltages. Additionally, the 3TF series has been largely superseded by the newer 3RT series (e.g., 3RT2015-1BB41), which offers similar ratings with enhanced features like electronic coil control and higher switching frequencies. However, the 3TF series remains popular for replacement and maintenance in existing installations.
