Product details

The Siemens 3RT2017-2HB42 is a SIRIUS coupling contactor in the size S00 frame. The contactor is rated for 10 A at 24 V and carries a typical mechanical life of 30,000,000 operations. Maximum switching frequency is 1,000 cycles per hour under AC-1 duty and 750 cycles per hour under AC-3 duty.

The 24 V DC coil is the critical selection parameter here — this contactor will not pull in on 24 V AC or higher DC voltages. Size S00 is the smallest SIRIUS contactor frame, so it fits where panel space is tight — 45 mm wide, 70 mm tall, 73 mm deep.

No auxiliary switch is included with this base unit — if you need auxiliary contacts, they must be ordered separately and snapped onto the side of the contactor.

Frequently asked questions

What is the closest functional alternative to the 3RT2017-2HB42?

The 3RT2017-2AH02-ZX95 is a peer variant — it shares the same S00 frame and spring-type terminals but has a different coil voltage. The 3RT2017-2HB42 is a 24 V DC coil unit; the 2AH02 variant uses an AC coil. They are not drop-in interchangeable without also swapping the coil supply.

What are the key dimensions of the 3RT2017-2HB42?

Width is 45 mm, height is 70 mm, and depth is 73 mm. It mounts on 35 mm DIN rail with 10 mm clearance needed above, below, and in front, and 6 mm at the sides.

What wire sizes does the spring-type terminal accept?

Solid or stranded wire from 0.5 to 4 mm² is accepted. For two conductors, use 2x (0.5 to 4 mm²).

What compliance documentation is available for this contactor?

The SIRIUS brand typically provides RoHS, REACH, and UL/CSA/CE declarations. Specific certificates for this order code should be requested with the RFQ.
