It measures from 0.05 A up to 10 A (the adjustable range), with a wider measurable span of 0.05 … 15 A available through the same input. The LCD display shows the actual current value and the set thresholds, so you can confirm the trip points without a clamp meter. The 0.05 … 10 A setting range covers small motor protection (fractional to about 5 kW at 400 V) and load monitoring on pumps, fans, or conveyors. The supply voltage accepts 20.4 … 264 V AC/DC — universal enough for 24 V control panels or 230 V line-powered installations without a separate supply module. Snap-on mounting on 35 mm DIN rail, 22.5 mm wide — fits a standard 1-module slot. Mounting position any, so it can go sideways or upside-down in a crowded cabinet. Operating temperature -25 … +60 °C, storage -40 … +85 °C. IP20 protection means it's touch-safe but not washdown-rated; install inside a panel with at least IP54 enclosure.","metaTitle":"Siemens 3UG4622-1AW30 SIRIUS Current Monitoring Relay, 0.05–","metaDescription":"Siemens 3UG4622-1AW30 SIRIUS current monitoring relay with digital setting, 0.05–10 A measuring range, LCD display, snap-on DIN rail mount.
