The AC-2 rating at 5.5 kW / 400 V is the motor-switching figure that governs real-world use: it confirms the contactor can handle the inrush and breaking duty of wound-rotor motors. For resistive loads (AC-12), the maximum operating current is 10 A. The contactor is also rated for DC switching at various voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the current limits for breaking DC inductive circuits, which arc differently than AC. The coil operates at 50/60 Hz with a voltage tolerance of 0.8 to 1.1 times the rated value. For type of coordination 2 (limited fault damage), the required upstream fuse is gL/gG 20 A; for type 1 (no damage to persons or installation, but contactor may need replacement), it is 35 A. ## Environmental limits and enclosure considerations The contactor is rated IP20 on the front and at the terminals, so it is touch-safe but not protected against water ingress — it must be installed inside a panel with a suitable enclosure rating.","metaTitle":"Siemens 3RT1317-2AN20 SIRIUS Power Contactor, S00, 4NO, 5.5","metaDescription":"Siemens SIRIUS 3RT1317-2AN20 power contactor, size S00, 4 NO main contacts, 5.5 kW at 400 V AC-2.
