The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° forward/backward tilt — useful when fitting into tight or non-standard panel layouts. ## Duty cycle and switching frequency The 3RT2035-1SF30 supports up to 1 000 switching cycles per hour in AC-1, AC-3, and AC-3e duty, 750 cycles/h in AC-2, and 300 cycles/h in AC-4. For a buyer comparing against a smaller SIRIUS frame like the S0 (3RT2016-1AG62), the S2 frame delivers higher mechanical endurance — 5 000 000 typical mechanical operations — and the wider coil voltage range, but the S0 is physically smaller (45 mm wide vs 55 mm) and may fit a panel where the S2 does not. The S2 is the better choice when the duty cycle demands the higher mechanical life or the coil voltage flexibility. The contactor measures 55 mm wide, 114 mm high, and 130 mm deep. Main and auxiliary wiring accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors. The auxiliary switch is built in, with 1 N/O + 1 N/C configuration (18 to 1). The 83-150 V coil draws 2 VA at both 50 Hz and 60 Hz, with an inrush peak of 25 A.","metaTitle":"Siemens 3RT2035-1SF30 SIRIUS S2 Power Contactor, 83-150V Coi","metaDescription":"Siemens 3RT2035-1SF30 SIRIUS S2 power contactor. 83-150V AC/DC coil, screw terminals, 52 a MTBF.
