Siemens SIRIUS 3RT2036-3AL20-ZW97 — Power Contactor, Size S2
The S2 frame size means this contactor occupies a defined footprint on the DIN rail: 55 mm wide, 114 mm tall, and 130 mm deep.
Ratings and Switching Capability
Rated operational current at AC-1 (resistive load) is 52 A at 480 V; at AC-3 (motor starting) the contactor handles 800 operations per hour maximum. For AC-4 (plugging/reversing) the rate drops to 250 operations per hour. The auxiliary switch is included, with 18 to 1 main contact configuration. Coil draw is 0.36 A at 50 Hz and 0.39 A at 60 Hz, with a pickup time of 10 to 18 ms and arcing time of 10 to 20 ms.
Spring-type terminals accept 2x (0.5 to 2.5 mm²) solid or stranded wire. The terminal design reduces wiring time and ensures vibration-resistant connections in industrial environments.
