Side-by-side mounting is supported, so you can pack multiple units without extra spacing. The IP20 front and terminal protection means it's suited for enclosed control cabinets, not open washdown areas. ## Ratings that matter for the panel The 24 VDC coil draws 3.3 W both during pickup and hold — no power drop after closure. That simplifies the DC supply sizing: each contactor pulls a steady 3.3 W whenever energized. The built-in varistor clamps the turn-off spike, so you don't need an external flyback diode across the coil. For the main contacts, the AC-3 motor rating at 400 V is 4 kW, and the AC-4 (inching/plugging) rating is 8.5 A at 400 V. If you're switching resistive loads, use the AC-1 curve; the 24 VDC resistive rating is 10 A. For DC switching at higher voltages, the rated current drops: 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. The order code suffix -0KV0 indicates the built-in varistor. If your panel already has external suppression, the base variant 3RT1016-1UB41 (without varistor) is a direct mechanical and electrical fit — same coil, same contact ratings, same footprint. ## Wiring and terminal detail Main circuit terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). AWG equivalents: 2x (20 to 16), 2x (18 to 14), or 1x 12. Auxiliary contact terminals have the same wire range. Depth is 72 mm, height 57.5 mm — fits standard 45 mm wide DIN-rail slot. The screw terminals are accessible from the front; no special tools needed beyond a standard screwdriver.","metaTitle":"Siemens SIRIUS 3RT1016-1UB41-0KV0 Power Contactor, 24 VDC, S","metaDescription":"Siemens SIRIUS 3RT1016-1UB41-0KV0 power contactor, 24 VDC coil, Size S00, 10 A at 24 VDC, screw terminals, built-in varistor.
