The magnet coil uses spring-type terminals, and the main contacts accept solid or stranded wire from 1 to 10 mm² (or 2x 0.5 to 2.5 mm² for finer stranded). That spring-cage termination means no screw-torque check during commissioning — strip, push, done. Maximum switching rate is 1,000 operations per hour for AC-1 (resistive), AC-2 (slip-ring motor), AC-3 (squirrel-cage motor start/run), and AC-3e loads. For AC-4 (plugging/inching) the rate drops to 300 ops/h — that's the one that governs if you're doing frequent reversing or jogging. The arcing time sits at 10 to 10 ms on AC, which is tight and consistent; the contactor clears fast, which helps with contact life on inductive breaks. ## Thermal limits and clearance requirements That -55 °C storage limit matters if the spare sits in an unheated warehouse over winter — it's fine sitting there, just don't try to switch it until it's above -25. That 6 mm side gap is tighter than some contactors; you can pack them closer side-to-side if your heat rise checks out.","metaTitle":"Siemens 3RT2024-2AP04 SIRIUS Power Contactor, S0 Size, Sprin","metaDescription":"Siemens 3RT2024-2AP04 SIRIUS power contactor, size S0, spring-type terminals, 45 mm width, 144 mm depth.

The 3RT2024-2AP04 uses spring-type terminals on the coil, while the 3RT2016-1AG62 may use screw terminals — check your existing wiring terminations. Main contact wire ranges overlap (1 to 10 mm² solid/stranded), so re-termination is usually straightforward if the lug type matches."},{"question":"What compliance documentation does Siemens provide for 3RT2024-2AP04?","answer":"As a standard SIRIUS catalog item, Siemens provides RoHS and REACH declarations, plus CE marking for the EU market.
