What it is and what it does
The Siemens 3RT2015-2AP02-ZW96 is a SIRIUS power contactor in the compact S00 frame size, designed for switching motor loads and resistive loads in industrial control panels. It carries a 24 VDC coil rated at 10 A and includes an auxiliary switch. The coil uses spring-type terminals, and the contactor mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, making it a direct fit for standard panel layouts.
Key ratings and what they mean for fit
The 24 VDC coil draws 10 A at rated value, which is the inrush and hold current the control circuit must supply. For a PLC or relay output driving this coil, verify the output can handle the 10 A peak — many solid-state outputs are rated lower and would need an interposing relay. Switching frequency varies by duty: up to 1 000 operations per hour at AC-1 (resistive loads), 750/h at AC-3 (standard motor starting), and 250/h at AC-4 (plugging or inching). For a conveyor line running frequent start/stop cycles, the AC-4 limit governs the service life. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. In a non-conditioned cabinet near a furnace or compressor, the 60 °C ceiling is the hard limit — the contactor must be derated or relocated if ambient exceeds that.
Where it is used
The S00 frame size is the smallest in the SIRIUS contactor family, suited for low-horsepower motors and auxiliary circuits where panel space is tight — 45 mm wide and 73 mm deep.
