The 24 VDC coil draws 2.3 W both on closing and holding, so your control transformer or DC supply needs to sustain that continuously, not just a pickup surge. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). No screw torque to verify — just strip to 8 mm and push. The auxiliary contact block is separate; this order code ships with zero instantaneous auxiliary contacts, so factor in a 3RH2911 or similar if you need feedback. The headline motor ratings are 4.5 kW at 500 V and 5.5 kW at 690 V in AC-3 duty — that's the standard induction motor switching category. For more demanding loads like reversing or inching (AC-4), the same contactor is rated 8.5 A at 400 V, so it handles frequent plugging or jogging within that current envelope. AC-1 resistive load rating hits 10 A at 230 V and 6 A at 400 V, covering heater banks or lighting contactor duty. The AC-2 rating of 4 kW at 400 V applies to slip-ring motor starting. For DC switching, the coil-side auxiliary contacts are rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are the make/break limits for pilot duty. The 45 mm width and 60 mm height fit standard S00 contactor spacing. The spring-loaded terminals reduce wiring time versus screw types, especially on repetitive builds. This matters when you're designing to IEC 60947-4-1 and need to publish SCCR values for the panel label. The coil's pick-up and hold power is flat at 2.3 W DC, so no thermal derating curve to worry about across the full temperature span for the coil itself.","metaTitle":"Siemens 3RT1016-2HB42 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1016-2HB42 power contactor, size S00, 24 VDC coil, spring-loaded terminals, IP20, current production.

It has lower motor ratings (around 3 kW at 400 V AC-3) and lacks the 690 V power class. The 3RT1016-2HB42 is the higher-rated spring-terminal variant; if your panel was wired for 3RT1015-1BB42, the 45 mm width and DIN rail footprint are the same, but check the coil voltage — the 1BB42 uses a different coil suffix."},{"question":"What compliance documentation is available for this contactor?","answer":"As a Siemens SIRIUS product, it carries CE marking for the European market and is designed to IEC 60947-4-1.
