Siemens SIRIUS S2 Power Contactor 3RT2036-3AP00
The Siemens 3RT2036-3AP00 is a SIRIUS S2-frame power contactor rated for 52 A at 480 V, making it a solid choice for switching motor loads and resistive circuits in industrial control panels. It mounts via screw or snap-on onto standard 35 mm DIN rail per DIN EN 60715, with spring-type terminals on the magnet coil for quick wiring. Rated for AC-3 duty up to 800 operating cycles per hour, this contactor handles frequent motor starting without overheating. The mechanical life is rated at 10 million cycles typical, so it's built for high-throughput lines where replacement downtime costs real money.
Mounting & Clearance
The 3RT2036-3AP00 fits a 55 mm wide DIN-rail footprint (114 mm tall, 130 mm deep). Required clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. The mounting position allows +/-180° rotation on a vertical surface and can be tilted forward/backward by +/-22.5° — useful when panel layout forces an odd angle.
