Product details

Fit and ratings — what matters for the BOM line

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. Clearance requirements: 10 mm upward and downward, 10 mm forward, 6 mm sideways. That covers most ventilated industrial enclosures.
