The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position flexibility of ±180° rotation and ±22.5° tilt on a vertical surface. The AC-3 maximum switching frequency of 750 1/h means this contactor is suited for standard motor starting duty — think conveyors, pumps, compressors — without overheating the coil or arc chamber. The AC-4 maximum of 250 1/h covers inching or plugging applications, so if your line does frequent reversing or jogging, stay within that lower cycle rate. The arcing time is a tight 10–10 ms, which keeps contact erosion predictable during fault clearing. The main contact wire range accepts solid or stranded conductors from 1 to 10 mm², and the auxiliary terminals accept 2x (0.5–2.5 mm²) — enough for standard control wiring. The S0 frame size (width 45 mm, height 102 mm, depth 107 mm) fits standard 35 mm DIN rail enclosures. The coil holds at 95–130 V AC; dropout occurs below the initial value of 0.7 times rated voltage.","metaTitle":"Siemens 3RT2027-2NF30 SIRIUS Power Contactor, S0 Frame, 95-1","metaDescription":"Siemens SIRIUS 3RT2027-2NF30 power contactor, S0 frame size, 95-130 V AC coil, spring-type terminals.
