The coil is 24 VDC with screw-type terminals, and the main contacts are rated for 18 A at 400 V AC-1 (resistive) and 40 A at 480 V AC-3. The auxiliary switch is included, with its own contact ratings across a range of control voltages — 10 A at 24 V, 2 A at 48 V, 1 A at 110 V, and so on down to 0.3 A at 220 V. Wire acceptance: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded. The S2 frame size keeps the panel footprint compact — 55 mm wide, 114 mm high, 130 mm deep. ## Environmental and operating limits The contactor is rated for up to 1 000 switching cycles per hour in AC-3 duty, 1 200 in AC-1, and 300 in AC-4 (plugging/inching).","metaTitle":"Siemens 3RT2035-1AK60-ZX95 SIRIUS S2 Power Contactor, 40 A a","metaDescription":"Siemens SIRIUS S2 power contactor 3RT2035-1AK60-ZX95, 40 A AC-3 at 480 V, screw terminals, 3-pole, 24 VDC coil.
