The Siemens SIRIUS 3RT2015-2AP01-1AA0 is a size S00 power contactor with a 24 VDC coil, designed for switching motor loads in control panels up to around 3 kW at 400 V. It uses spring-type terminals for wiring and mounts on a 35 mm DIN rail per DIN EN 60715, fitting into compact panel layouts where the 45 mm width and 73 mm depth matter for rail spacing.
Key ratings and what they mean for fit
The 24 VDC coil draws 10 A at rated value, which is the pick-up current; the holding current is lower, but the 10 A figure governs the DC supply sizing and the free-wheel diode selection across the coil. At 400 V the contactor is rated 3 A, so it handles small motor loads — think fractional-horsepower pumps or small conveyors — not a 10 kW drive feed. The size S00 frame keeps the panel footprint tight, and the spring-type terminals accept 0.5 to 4 mm² solid or stranded wire, which covers standard control wiring without needing ferrules for stranded conductors. Operating temperature spans -25 to +60 °C, so it works in an unventilated enclosure near hot rolls or a furnace line, but the storage range of -55 to +80 °C is wider — that limit governs handling during shutdown, not running. The auxiliary switch is built in, saving a separate add-on block for status feedback to the PLC.
Mounting and integration
Snap-on mounting onto a 35 mm DIN rail per DIN EN 60715, with a screw option for vibration-heavy environments. The mounting position is standing on a horizontal surface. Clearance: 10 mm upwards and forwards, 6 mm at the side, 10 mm downwards — these matter for heat dissipation and arc-chamber clearance when the contactor is packed next to other devices in a row.
