Depth of 73 mm means it clears most 120 mm deep enclosures with space for wiring behind the rail. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). That's a standard range for motor circuits up to 4 kW — no need for ferrule adapters on the smaller sizes, but the double-wire entry is handy for daisy-chaining the line side through a disconnect. ## Coil and control circuit — what the ratings mean The holding current will be lower, but the inrush matters for sizing your 24 VDC power supply. If you're running a bank of these, sum the pickup currents to avoid a voltage dip that drops out adjacent contactors. Coil operates reliably across 0.85 to 1.1 times the rated voltage at both 50 Hz and 60 Hz. That's a 20.4 V to 26.4 V window — tight enough that a sagging 24 V bus from a long cable run could cause chatter. Keep the DC supply local or use a regulated rail. ## Short-circuit protection and coordination That's the standard choice for motor circuits where you want the contactor to survive a fault and be reusable. The 3 kW AC-2 rating at 400 V corresponds to roughly a 7 A full-load current for a 400 V motor — the 20 A fuse gives a 3:1 margin for starting inrush without nuisance blowing. For a 4 kW motor at 690 V, the same contactor handles it, but the fuse sizing should be checked against the motor nameplate FLA.","metaTitle":"Siemens 3RT1015-2AR61 SIRIUS S00 Contactor, 24 VDC, 3 kW AC-","metaDescription":"Siemens SIRIUS 3RT1015-2AR61 power contactor, size S00, 24 VDC coil, 3 kW AC-2 at 400 V, spring-cage terminals, current production.
