The AC-3 and AC-3e maximum switching frequency is 800 operations per hour; AC-4 duty (plugging/reversing) is rated at 250 ops/h. The S0 footprint is 55 mm wide, 85.5 mm tall, 91 mm deep — a standard slot in most panel layouts. That helps when fitting into tight enclosures or angled subpanels. ## Terminals and wiring Both main and auxiliary/control circuits use screw-type terminals. The main circuit accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire, and the same for finely stranded with ferrules. ## Protection and coordination For short-circuit protection, type 1 coordination calls for an 80 A gL/gG NH fuse; type 2 coordination requires a 35 A gL/gG NH fuse. That gives you a clear fuse sizing rule for the bill of materials.","metaTitle":"Siemens 3RT7026-1AM05 Contactor, S0 Frame, 3-Pole","metaDescription":"Siemens 3RT7026-1AM05 SIRIUS contactor, S0 size, 3-pole, 3 NO main contacts, screw terminals, 55mm wide.
