The 3RT2035-1NB30: Mechanical life is 10 million operations typical, with rated AC-3 duty at 1 000 cycles per hour — a solid baseline for motor-switching applications up to that frequency. Mounting is screw or snap-on onto 35 mm DIN rail per EN 60715. Clearance requirements: 10 mm upward and downward, 10 mm forward, 6 mm sideways. Operating temperature range is -25 to +60 °C; storage to +80 °C. That covers most ventilated industrial enclosures.
The width is 55 mm and the depth is 130 mm. Height is 114 mm.
