Product details

The Siemens 3RP1540-2AN31 is a SIRIUS time relay with an adjustable timing range of 0.05 to 600 seconds, powered by a 200–240 VAC/DC control supply. It delivers a 5 A thermal current rating and mounts via screw or snap-on onto a standard 35 mm DIN rail — the usual panel integration for control cabinets. The relay output switches at 1 A at 24 V, 0.2 A at 125 V, or 0.1 A at 250 V, so it handles pilot-duty signalling loads rather than direct motor switching.

Integration & Environment

The 22.5 mm width and 84 mm height fit standard DIN-rail enclosures; mounting position is any, so it can be oriented for tight panel layouts. Operating temperature range is -25 to +60 °C, with storage and transport tolerance from -40 to +85 °C. Basic insulation and pollution degree 3 suit it for industrial control panels without special isolation barriers.
