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.","metaTitle":"Siemens 3RT2017-2HB42 SIRIUS Coupling Contactor, Size S00, 2","metaDescription":"Siemens 3RT2017-2HB42 SIRIUS coupling contactor, size S00, 24 VDC coil.
