Frequently asked questions

What is the purpose of the FTFM function in the Siemens 3VA5125-6ED31-0AA0 circuit breaker?

The FTFM (Fixed Thermal-Fixed Magnetic) function in the Siemens 3VA5125-6ED31-0AA0 ensures reliable protection against both sustained overloads (thermal) and instantaneous short circuits (magnetic). The overload setting (Ir) is permanently set to 25A, and the short-circuit setting (Ii) is fixed at 12 times the nominal current.
