That wide-range coil is the key differentiator — it simplifies panel wiring because you don't need separate AC and DC coil variants, and it rides through brownouts better than a tapped-coil design. The 175 V minimum pull-in means it stays latched on a sagging 208 V line, which matters for sites with weak utility feeds. Main contact ratings: 10 A at 24 V and 230 V, 3 A at 400 V. The auxiliary switch is included, so you get a spare N.O./N.C. set for status feedback or interlocking without adding a side-mount block. Operating temperature range -40 to +70 °C, storage down to -55 °C. That -40 °C low end is unusual for a standard contactor — it's rated for unheated enclosures in cold climates or freezer-plant applications. ## Panel Integration & Wiring The snap-on feature speeds installation on a production line — push on, no tools. Screw terminals on the coil accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid/stranded, which covers most control-circuit wiring up to 14 AWG. Dimensions: 75 mm wide, 114 mm high, 130 mm deep — that's a compact S2 footprint, leaving room for a side-mount auxiliary block or a solid-state timer on the rail. That 6 mm side gap is tight — you can pack contactors rail-to-rail without a big air gap, which matters when you're squeezing 10 contactors into a 600 mm wide enclosure. The 10 mm vertical clearance is standard for finger-safe wiring duct. ## Performance & Coordination Coil inrush peaks at 5 A, holding at 2 VA (50/60 Hz). That's a low burden on a PLC output or a 24 VDC power supply — you can drive it directly from a typical 0.5 A solid-state relay without a booster. Compared to the 3RT2027-1NP30-ZX95 (a smaller S0 frame), the S2 frame of the 3RT2336-1NP30 gives you higher continuous current capacity and a wider coil voltage range. The S0 tops out around 7 A at 400 V; the S2 handles 3 A at 400 V but with a larger contact gap for better arc extinction. If your load is under 5 A at 400 V and you need the smallest footprint, the S0 is the tighter fit; for the 175-280 V coil flexibility and the cold-temperature rating, the S2 is the better pick.","metaTitle":"Siemens SIRIUS 3RT2336-1NP30 Contactor, S2, 175-280V AC/DC C","metaDescription":"Siemens SIRIUS 3RT2336-1NP30 contactor, size S2. 175-280V AC/DC coil, 10A at 24V/230V, 3A at 400V.

The S2 frame is 75 mm wide vs. the S0's 45 mm, and the depth is 130 mm vs. roughly 100 mm for the S0. The DIN rail mounting is the same, but the larger S2 may require shifting adjacent components or a wider enclosure. The wiring terminal sizes are similar (2x 0.5-2.5 mm²), so rewiring is not needed if the panel has spare space."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2336-1NP30","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT2336-1NP30 when reusing this data.
