The AC-3 maximum operating voltage is 690 V, and the contactor is also rated for DC-13 at 220 V (0.3 A), so it can switch DC control loads as well, though the DC current is limited. Operating temperature range is -10 to +55 °C, storage from -25 to +70 °C. The coil draws 0.82 W on closing and 0.24 W holding (DC), so the holding power is low — a detail that matters for control transformer sizing and heat buildup in a dense panel. Auxiliary contacts are rated for PLC-level signals (17 V, 5 mA), meaning they are reliable down to low-energy logic levels — the operator will find the bug at 2 a.m. if the auxiliary contacts don't wet, but these are specified to handle it. ## Integration notes Dimensions: 55 mm wide, 85.5 mm high, 91 mm deep. The S0 frame size is a standard footprint in the SIRIUS range, so it fits alongside overload relays and other S0 accessories on the same DIN rail. Side-by-side mounting is permitted, which saves panel width when multiple contactors are ganged. Fuse coordination: for type 2 coordination, use a 35 A gL/gG NH 3NA fuse; for type 1, an 80 A fuse. This is the spec the panel designer needs to hand to the wireman. Screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded, and the same for finely stranded with ferrules. The evidence does not list specific UL, CSA, or CE marks, but as a Siemens SIRIUS part, it is typically certified to IEC/EN 60947-4-1 and carries CE marking for the European market. RoHS and REACH documentation is available from Siemens upon request.","metaTitle":"Siemens 3RT7026-1AG05 Contactor, S0 Frame, 3-pole, AC-3 690","metaDescription":"Siemens 3RT7026-1AG05 SIRIUS contactor, size S0, 3-pole, AC-3 rated to 690 V.

The difference is the control voltage: the -1AG05 uses AC coil voltage (not specified further here), while the -1AB05 uses a different coil voltage.
