Auxiliary contacts are rated for PLC-level reliability (17 V, 5 mA), meaning they can switch low-energy signals without oxide-film issues. The S0 footprint is 55 mm wide, 85.5 mm tall, and 91 mm deep — a compact block that fits standard panel layouts. Side-by-side mounting is allowed with no derating gap, so multiple contactors pack tightly on the rail. For Type 2 coordination (minimal contact damage on fault), the required upstream fuse is a gL/gG NH 3NA: 25 A.","metaTitle":"Siemens 3RT7025-1AH05 SIRIUS Contactor, 3-Pole, AC Coil, S0","metaDescription":"Siemens 3RT7025-1AH05 SIRIUS contactor, 3-pole, AC coil, S0 size.
