The contactor carries an integral auxiliary switch, saving a separate aux block on simple reversing or interlocking circuits. The headline switching capacity is defined across multiple voltage levels for DC-13 duty (solenoid loads). At 24 V rated value it switches 10 A; at 48 V and 60 V it handles 2 A; at 110 V it switches 1 A; at 220 V it drops to 0.3 A; and at 600 V it still manages 11 A. The AC motor-duty ratings (AC-3) govern the maximum switching frequency: 750 operations per hour at AC-2, AC-3, and AC-3e, and 1 000 ops/h at AC-1 resistive load. AC-4 (plugging/inching) is limited to 250 ops/h. ## Mounting and integration into a panel The contactor measures 45 mm wide, 58 mm high, and 73 mm deep — a footprint that fits tightly on a DIN rail alongside other S00-frame components.","metaTitle":"Siemens 3RT2017-4BB42 SIRIUS Contactor, Size S00, 24 VDC Coi","metaDescription":"Siemens 3RT2017-4BB42 SIRIUS power contactor, size S00, 24 VDC coil with ring cable lug.
