Product details

The 24 VDC coil draws its rated current of 10 A at 24 V — that's the current the main contacts handle, not the coil draw. Spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², so no ferrule crimping needed for fine-stranded conductors. Mounts via screw or snap-on onto 35 mm DIN rail per EN 60715, with ±180° rotation on a vertical surface and ±22.5° tilt forward/backward allowed.

Dimensions and mounting clearances

The contactor measures 45 mm wide, 70 mm high, and 73 mm deep. Maintain at least 10 mm clearance upwards, 10 mm downwards, 10 mm forwards, and 6 mm at the sides for proper ventilation and arc quenching. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.

Switching performance and mechanical life

Rated for 1,000 operations per hour at AC-1, 750/h at AC-2 and AC-3, and 250/h at AC-4. Mechanical endurance is 30 million operations typical. Arcing time is 10 to 15 ms, and the DC dropout delay is 7 to 20 ms — useful when coordinating with a PLC output that needs to hold in during a brief sag.

Frequently asked questions

How do I get current pricing and availability for 3RT2016-2KB41?

Submit an RFQ through this listing. The part is sourced to order through independent distribution, and pricing and availability are confirmed at quote time.

What is the closest functional second-source to 3RT2016-2KB41?

The 3RT2015-2HB41 is a functional peer in the same SIRIUS S00 family, but it uses a different coil voltage (24 VAC vs 24 VDC) and has a lower rated current. Verify your coil supply and load current before substituting.

What is the depth of 3RT2016-2KB41?

The depth is 73 mm.

What wire sizes does the spring terminal accept?

Solid or stranded wire from 0.5 to 4 mm², and 2x (0.5 to 4 mm²) for paralleled conductors.

Will 3RT2016-2KB41 drop into a panel designed for 3RT2015-2HB41 without rewiring?

Both are S00 frame size with the same DIN-rail footprint, so mechanical fit is identical. However, the coil voltage differs (24 VDC vs 24 VAC), so the control circuit must be rewired to match the DC coil.
