Rated for 6 A at 24 V and 230 V, 3 A at 400 V, and 1 A at 690 V — the switching capacity drops as voltage climbs, so size for the worst-case circuit voltage, not the 24 V figure. The coil pulls in between 0.7 and 1.3 times rated voltage at both 50 and 60 Hz, and the operating time is 30-50 ms on both AC and DC — consistent pickup across supply types. No attachable auxiliary switch block is listed (0 attachable), so any added contact block requires a separate mounting or a different contactor variant. ## Terminal Capacity & Wiring Screw terminals accept solid wire: 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm². Stranded: 2x 1-2.5 mm² or 2x 2.5-10 mm². At 40 °C ambient, the main circuit accepts up to 1x 16 mm²; at 60 °C, up to 1x 25 mm² — derating for temperature means larger wire at higher ambient. Dimensions: 45 mm wide, 150 mm high, 165 mm deep. The 165 mm depth is the key panel clearance number — make sure the enclosure depth exceeds that with room for wiring. The storage range is wider — that limit governs handling, not running. ## Switching Rate & Arcing Maximum switching rate: 100 operations/hour at 230 V, 240 V, and 400 V; drops to 70/h at 480 V, 65/h at 500 V, 45/h at 600 V, and 36/h at 690 V. Arcing time is 10 ms — consistent, not a variable. Factor that into contactor life calculations for high-cycle applications.","metaTitle":"Siemens 3RT2628-1NF35 Contactor, 95-130 V AC/DC, 45 mm","metaDescription":"Siemens 3RT2628-1NF35 contactor with 95-130 V AC/DC coil. 6 A at 24 V, 6 A at 230 V, 3 A at 400 V.
