The adjustable time range spans 0.05 to 100 seconds, giving you a wide window for delayed start or sequenced motor engagement without an external timer module. The recovery time is 150 ms, meaning the relay resets quickly between cycles — relevant for rapid restart sequences in conveyor or pump applications where the motor must re-engage after a brief stop. ## Mounting and panel fit — clip-on DIN rail, any orientation Fastens via clip-on onto standard DIN rail, with a width of 45 mm, depth of 74 mm, and height of 38 mm. The mounting position is unrestricted — install it in any orientation, same as a contactor — which simplifies panel layout when space is tight. Clearance around the unit is zero in all directions (upwards, forwards, backwards, downwards, at the side), so it can be stacked directly against adjacent devices without derating for spacing. ## Environmental limits — storage and operation Rated for operation from -25 °C to +60 °C, with storage and transport tolerance from -40 °C to +85 °C. The basic insulation type covers standard industrial panel environments — no special derating needed for typical control cabinet conditions.","metaTitle":"Siemens 3RA2815-1AW10 SIRIUS Motor Starter, 3 A","metaDescription":"Siemens 3RA2815-1AW10 SIRIUS motor starter, 3 A max, adjustable time 0.05-100 s, AC/DC 24-240 V.
