Panel fit and mounting constraints
The 3RT2016-2HB41: Clearance requirements: 10 mm above and below, 10 mm forward, 6 mm on each side — plan the DIN rail spacing accordingly when packing multiple contactors in a row.
Switching duty and operating limits
Rated for DC switching at 24 V (10 A), 48 V (2 A), 60 V (2 A), 110 V (1 A), 125 V (0.9 A), and 220 V (0.3 A) — the DC arc extinction limits the current sharply above 48 V, so check your DC load against the curve, not the AC rating.
