Product details

At 55 mm wide and 174 mm deep, it occupies a standard S2 footprint — the same width as the 3RT2027 frame but deeper, so a panel laid out for the smaller contactor may need clearance for the extra 20 mm or so behind the DIN rail.

Switching Performance and Duty Ratings

The 3RT2035-1AD04 is rated for 1 200 operations per hour in AC-1 (resistive) duty, 1 000 ops/h in AC-3 (squirrel-cage motor starting), and 300 ops/h in AC-4 (plugging/inching). The AC-3e rating matches the standard AC-3 at 1 000 ops/h. These are the maximum mechanical switching rates — actual thermal limits depend on the load current and enclosure derating. Arcing time is 10 to 20 ms, and operate time at AC is 10 to 18 ms. Main contacts are rated for 18 to 1. Mechanical life is typical 10 000 000 operations.

Coil and Auxiliary Details

The magnet coil uses screw-type terminals, accepting solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²). No auxiliary switch is integrated on this base unit — add a separate auxiliary contact block if needed. Coil ratings at various control voltages: 6 A at 24 V rated value, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V, 40 A at 480 V, 2 A at 500 V. At 50 Hz the coil is rated for 42 V. At 230 V rated value, the contactor carries 7.5 hp.

Frequently asked questions

What are the key dimensions of 3RT2035-1AD04?

Width is 55 mm, height is 114 mm, depth is 174 mm.

Does 3RT2035-1AD04 drop into a panel designed for 3RT2027-1AB04?

Both are SIRIUS S2 contactors with 55 mm width, but the 3RT2035 is deeper at 174 mm vs the 3RT2027's typical depth. The DIN rail mounting and screw-terminal coil are the same, so it will fit the same rail but may require additional rear clearance.
