At 45 mm wide, 58 mm tall, and 73 mm deep, it fits into tight gland-plate layouts where every millimeter of DIN rail counts. The coil is rated at 24 VDC, and the main contacts carry 10 A at 24 VDC resistive (AC-1) and 3 A at 400 VAC. That AC-1 number — 10 A — is the resistive load curve; if you're switching motor loads under AC-3 duty, the contactor handles up to its rated operational current for that category, which for this frame size typically lands below the resistive figure. The switching frequency tops out at 1,000 operations per hour for AC-1, 750 per hour for AC-3, and 250 per hour for AC-4 (plugging/reversing). Those limits aren't theoretical — exceed them on a frequent-start conveyor and you'll cook the arc chamber. The 10 mm clearance above and below, plus 6 mm to the side, is the minimum for arc flash and heat dissipation — don't cram it flush against the enclosure wall. Screw-type terminals on the coil and main contacts accept solid or stranded wire from 0.5 to 4 mm², or two conductors in parallel (2x 0.5...1.5 mm², 2x 0.75...2.5 mm², or 2x 4 mm²). Just keep the arc chamber clearances I mentioned above.","metaTitle":"Siemens 3RT2016-1UB41 SIRIUS Contactor, 24 VDC Coil, Size S0","metaDescription":"Siemens 3RT2016-1UB41 SIRIUS power contactor, Size S00, 24 VDC coil, screw terminals, 10 A at 24 VDC.

Availability and current pricing are confirmed at quote time — submit an RFQ to get a firm number and lead time."},{"question":"Will the 3RT2016-1UB41 drop into a panel built for the 3RT2016-1AG62?","answer":"Mechanically yes — both are Size S00, same 45 mm width, same DIN rail footprint and screw-mount pattern. The difference is the coil: the 1UB41 uses 24 VDC, while the 1AG62 uses an AC coil. If the panel already has a 24 VDC supply rail, it's a straight swap. If it's wired for 230 VAC, you'll need to add a DC power supply or change the coil voltage."},{"question":"What is the depth of the 3RT2016-1UB41?","answer":"The depth is 73 mm. That's the dimension from the DIN rail mounting surface to the front of the contactor body — includes the terminals but not any overhang from auxiliary contact blocks mounted on the side."},{"question":"What wire sizes does the 3RT2016-1UB41 accept?","answer":"Solid or stranded wire from 0.5 to 4 mm². It also accepts two conductors per terminal: 2x 0.5...1.5 mm², 2x 0.75...2.5 mm², or 2x 4 mm².
