Main contacts rated for AC-3 switching up to 690 V maximum; the DC-13 rating at 220 V is 0.3 A, so don't expect heavy DC load handling from this AC-optimized coil variant. ## Mounting and integration — panel fit 45 mm wide, 85.5 mm tall, 91 mm deep — the S0 footprint is standard across the SIRIUS contactor family. That gives you options when the panel layout is tight. Wire range: 2x (0.5…1.5 mm²) solid/stranded or 2x (0.75…2.5 mm²) finely stranded with ferrule. Auxiliary switch blocks can be added on the front — the product extension is supported. Coil draw: 0.82 W closing, 0.24 W holding at DC. Shock resistance: 12.5g / 5 ms or 7.8g / 10 ms sine pulse. Acceptable for PLC-level control signals (17 V, 5 mA) on the auxiliary contacts. For type 1 coordination (no weld prevention, just no fire risk on fault), use gL/gG NH 3NA fuses rated 80 A. For type 2 coordination (limited contact welding), step down to 35 A fuses. Maximum mechanical switching rate: 800 cycles/hour at AC-3, 250 cycles/hour at AC-4. Ambient operating range -10…+55 °C; storage -25…+70 °C.","metaTitle":"Siemens 3RT7026-1AF00 S0 Contactor, 3-Pole AC Coil, IP20","metaDescription":"Siemens 3RT7026-1AF00 S0 contactor, 3-pole, AC coil, IP20 finger-safe.

The 3RT7026-1AF00 is the newer SIRIUS generation; the 3RT6026 is the previous series. Both share the same 45 mm width, 35 mm DIN rail footprint, and screw terminal pattern, so a panel designed for the 3RT6026-1AN20 should accept the 3RT7026-1AF00 without rewiring. The deciding factor is lifecycle: the 3RT7026 is current production, while the 3RT6026 may be harder to source new."},{"question":"Where can I buy 3RT7026-1AF00?","answer":"Sourced and quoted to order against an RFQ through independent distribution.

Both are S0-frame contactors with the same 45 mm width, same 35 mm DIN rail mounting, and same screw terminal layout. The 3RT7026-1AF00 is the direct current-production replacement for the earlier 3RT6026 series, so no rewiring or panel modification is needed."},{"question":"What are the key dimensions of 3RT7026-1AF00?","answer":"Width 45 mm, height 85.5 mm, depth 91 mm.
