Rated control supply voltage is 24 to 240 V AC/DC, covering most common control voltages in industrial panels without needing a separate power supply module. Measurable voltage range is 0 to 400 V AC at line frequencies of 50 to 60 Hz, so it fits standard mains networks across global sites. The relay includes a delayed switching function with one delayed switching element, plus an error memory that latches the alarm state until manually reset — useful for unattended substations where you need to know an intermittent fault occurred.
Mounting position is any, so orientation is not a constraint in crowded panels. Dimensions: 78 mm high, 22.5 mm wide (one standard module width), 100 mm deep. Screw-type terminals accept solid wire 1x (20–12 AWG) or 2x (20–14 AWG), and stranded wire 1x (18–14 AWG) or 2x (18–16 AWG). Stripping length and torque are per standard Siemens practice for this terminal family. Clearance distances: upwards, forwards, backwards, downwards, and to the side are all 0 mm — meaning no mandatory air gap to adjacent components, though practical creepage distances for the 6 kV surge rating should be observed.
Ambient temperature range during operation: -25 to +60 °C, covering most indoor industrial environments without derating. Surge voltage resistance rated at 6 kV.
