The coil is a 24 VDC type with a pick-up threshold of 0.85 x rated voltage and a drop-out of 1.1 x rated voltage, so it holds cleanly at nominal 24 V and drops out reliably below about 20.4 V. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire, which speeds wiring and eliminates screw torque checks. The mechanical life is 10 million cycles typical, so it outlasts most panel refreshes. Operating temperature range is -25 to +60 °C, storage -55 to +80 °C, and it's rated for altitudes up to 2 000 m without derating. The IP20 finger-safe enclosure on the front and terminals means it's safe for open-panel installation where qualified personnel access the enclosure. ## Switching performance and coil characteristics Operating time at DC is 7 to 10 ms, arcing time 10 to 15 ms — fast enough for most motor start/stop sequences. The maximum switching rate at AC-1 (resistive load) is 1 000 operations per hour. Coil inrush at 24 VDC is 10 A, dropping to a holding current that varies with voltage: 2 A at 60 VDC, 1 A at 110 VDC, 0.3 A at 220 VDC. For AC coils, draw is 6 A at 230 V, 3 A at 400 V, 0.8 A at 440 V. For DC-13 (solenoid) loads at 24 V, the maximum permissible current is 0.01 A — this is a signal-level switching spec, not a power contact rating.","metaTitle":"Siemens 3RT1517-2BB48-0KT7 SIRIUS Power Contactor, S00, 24 V","metaDescription":"Siemens SIRIUS power contactor 3RT1517-2BB48-0KT7, size S00, 24 VDC coil, 3 NO + 1 NC, spring terminals, IP20, current production.
