Siemens 3UF7100-1AA00-0 Relay

Siemens 3UF7100-1AA00-0 is a current measuring module for the SIMOCODE PRO CU motor-management system, providing accurate current sensing as part of Siemens' motor-control solutions. It includes a built-in Durchsteckwandler (through-connecting transformer) and is specified for measuring currents from 0.3 to 3 A, enabling reliable monitoring of motor load within the SIMOCODE PRO CU ecosystem. With a 45 mm width, the module is designed for compact installation alongside other SIMOCODE components in standard control panels. The part is cataloged as 3UF7100-1AA00-0 in Siemens’ Industry Mall listings and is marketed by Siemens distributors under the SIMOCODE current-measuring family, reflecting its role as a dedicated current-measuring module rather than a standalone relay. Typical uses include motor-control applications where real-time current feedback informs protection logic and drive-control decisions in equipment such as automated lines, conveyors, and pump stations. The 3UF7100-1AA00-0 is a plug-in current-measuring module that integrates with SIMOCODE PRO CU, delivering a compact, Siemens-approved solution for monitoring motor currents without requiring additional sensing hardware.
