It carries a 690 V rated insulation voltage and a 6 kV rated surge voltage resistance, meaning it's built for 400 V line-to-line systems with decent headroom for transient spikes — pollution degree 3 environment, so it's comfortable in a typical industrial control panel without sealed enclosures. The 55 mm width and 115 mm depth put it in the standard S2 footprint; it mounts via screw or snap-on onto 35 mm DIN rail per EN 50022, and the mounting position is flexible — you can rotate it ±180° on a vertical surface or tilt it ±22.5° forward or backward, which helps when you're squeezing it into a crowded backplate. ## Coil options and auxiliary extension The coil draws 6 A at 24 V rated value, 1 A at 110 V, and 0.3 A at 220 V — the 24 V version is the common pick for PLC-driven panels, but the 110 V and 220 V taps give you flexibility if you're working with older control transformers or a mixed-voltage cabinet. The contactor accepts auxiliary switch extensions (product extension auxiliary switch: yes), so you can add feedback contacts for PLC status monitoring or interlocking without a separate relay block. ## Wiring and protection coordination Main and auxiliary circuits both use screw-type terminals, accepting 2x (0.75 to 16 mm²) solid or stranded wire, or 2x (18 to 2) AWG. The minimum permissible cross-section at both 40 °C and 60 °C is 16 mm² — that's the same at both temperatures, so no derating on wire size when the panel runs hot. For short-circuit protection, the manufacturer specifies a fuse gL/gG: 63 A when using type of assignment 2 coordination. The power factor at 50 Hz is 0.36 — that's the coil's power factor, not the motor load, so factor it into your control transformer sizing if you're running multiple contactors on one transformer. ## Mechanical and electrical endurance Mechanical life is rated at 10,000,000 typical cycles, with a maximum operating frequency of 5,000 1/h at AC, 1,200 1/h at AC-1 maximum, 1,000 1/h at AC-3 maximum, and 300 1/h at AC-4 maximum. Substance prohibition date is 03/01/2017 — that's the RoHS compliance effective date for this part, so it meets the EU RoHS directive for hazardous substance restrictions.","metaTitle":"Siemens 3RT5035-1AM00 SIRIUS Power Contactor, 55 mm, 690 V","metaDescription":"Siemens 3RT5035-1AM00 SIRIUS S2 power contactor, 55 mm wide, 690 V insulation, 38 kW at 400 V 60 °C.
