The Siemens SIRIUS 3UF7114-1BA01-0 is a current/voltage measuring module with overload protection rated CLASS 5E. It detects current, voltage, and frequency on AC supplies from 110 to 690 V at 50/60 Hz. Energy measurement accuracy runs ±5% from 47 to 1260 A, and ±10% from 1260 to 5040 A, both at 25 °C within the defined voltage and power factor range. Trip class 5E means it handles motor protection with a shorter thermal memory curve — useful for frequent starts or when you need tighter overload differentiation.
