Its coil is rated for 72…125 V DC with an extended operating range, meaning it holds in reliably even if the DC supply sags toward the lower end of the band — useful on long cable runs or shared power supplies where voltage drop is a concern. The coil terminates via spring-type terminals, so no screwdriver torque is needed on the control wiring. Side-by-side mounting is allowed, so multiple contactors can pack tightly on the rail without derating spacing. ## Mounting & Integration Notes The spring-type coil terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm² solid conductors — strip length is standard for spring-cage terminations. Main contact wiring uses the same spring-clamp system; no screwdriver calibration needed. The coil inrush current peaks at 1.1 A at 72–125 V DC, then settles to a holding current determined by the full-scale value of 1.25 and the initial value of 0.7 — these parameters define the coil's thermal load on the DC supply. For AC-4 duty (plugging / inching), the maximum switching rate is 250 operations per hour. The auxiliary switch is included, so no separate add-on block is needed for status feedback. Mechanical life is typical at 30,000,000 operations.","metaTitle":"Siemens 3RT2317-2XF40-0LA2 SIRIUS Power Contactor, 72-125 V","metaDescription":"Siemens SIRIUS 3RT2317-2XF40-0LA2 power contactor, Size S00, 45 mm wide, 72-125 V DC coil with extended operating range.
