Siemens SIRIUS 3UF7104-1BA00-0 is a current measuring module that sits in the motor feeder circuit to detect current and provide overload protection. It operates on AC supplies rated 110-690 V at 50 or 60 Hz, draws 0.2 W, and offers a trip class of CLASS 5E. The module carries UKCA approval (ITS21UKEX0464) and meets RoHS requirements (substance prohibitance date 07/01/2006), which covers compliance documentation for most cross-border procurement lines.
The module measures 145 mm wide, 147 mm high, and 148 mm deep, with a required top clearance of 30 mm and bottom clearance of 30 mm; left and right clearances are 0 mm. That 30 mm top gap is the one that catches panel layout—plenty of headroom for cable entry or busbar pass-through. It mounts in any position, directly or stand-alone, so no special DIN rail adapter needed. Protection class IP00 means it needs to be inside an enclosure. Rated for ambient operation from -25 to +60 °C, with storage and transport tolerance from -40 to +80 °C, and altitude derating: 2 000 m max; 3 000 m at +50 °C; 4 000 m at +40 °C (no protective separation). Vibration resistance: 1-6 Hz at 15 mm, 6-500 Hz at 2 g.
