The S00 frame means this contactor occupies 45 mm width on a DIN rail, with a depth of 114 mm and height of 57.5 mm — tight enough for dense panel layouts where every millimeter of rail space counts. The 5.5 kW rating at 690 V is the AC-3 motor switching capability — that's the real-world number for sizing this contactor to a three-phase induction motor. At 400 V, the AC-3 rating drops to 3 A (about 1.5 kW), so don't assume the 690 V figure scales linearly; the contactor's thermal current rating and the duty cycle govern the actual load it can handle continuously. The mechanical life of 30 million operations is typical for a contactor this size, but the electrical life will be shorter under full-load switching — expect around 1 to 2 million operations at rated AC-3 current, depending on the switching frequency and the inrush current of the motor. The screw terminals accept wire from 0.5 to 4 mm² (solid or stranded), with AWG equivalents from 20 to 12. That covers most control wiring and small power feeds, but if you're running 6 mm² or larger, you'll need to step up to the next frame size. The IP20 rating on the front and terminals means it's finger-safe for panel installation — no special cover needed inside a locked enclosure. The 6 mm side clearance requirement is for heat dissipation when mounting multiple contactors side-by-side; if you pack them tight, derate the continuous current per the manufacturer's table. The operating temperature range of -25 to +60 °C covers most indoor industrial conditions, but above 40 °C you'll need to derate the continuous current — the coil hold-in voltage also shifts with temperature, so verify the control voltage stays within the 0.8 to 1.1 range at the panel's ambient temperature. Side-by-side mounting is allowed, but maintain the 6 mm gap between contactors for airflow unless you're derating. The screw terminals are the standard for the main circuit; auxiliary contact blocks (like the 3RT1916 series) snap onto the front or side without additional wiring. The coil terminals are also screw type, so you'll need a small flathead or Pozidriv for termination. For type 2 coordination (contactor remains usable after a fault), use a 20 A gL/gG fuse. This is critical for panel builders specifying the correct branch circuit protection.","metaTitle":"Siemens 3RT1016-1AL05 SIRIUS Power Contactor, S00 Frame, 24","metaDescription":"Siemens 3RT1016-1AL05 SIRIUS power contactor, size S00, 3-pole, 24 VDC coil, screw terminals, 5.5 kW at 690 V, IP20 front, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"114 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"57.5 mm","Maximum":"2 000 m","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","At The Side":"6 mm","On The Front":"IP20","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","Mounting type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Of The Terminal":"IP20","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Size of contactor":"S00","Product brand name":"SIRIUS","Degree of pollution":"3","Product designation":"power contactor","at 24 V rated value":"10 A","at 60 V rated value":"2 A","Of Contactor Typical":"30 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 50 Hz rated value":"125 V","at 500 V rated value":"4.5 kW","at 60 Hz rated value":"125 V","at 690 V rated value":"5.5 kW","Instantaneous Contact":"3","Side-by-side mounting":"Yes","For Main Current Circuit":"screw-type terminals","Single Or Multi-Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 mm²)","at AC-2 at 400 V rated value":"4 kW","at AC-4 at 400 V rated value":"8.5 A","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","at AWG conductors for main contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","With Type Of Coordination 1 Required":"fuse gL/gG: 35 A","Reference code acc. to DIN EN 81346-2":"Q","Number of NC contacts for main contacts":"0","Number of NO contacts for main contacts":"3","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number of poles for main current circuit":"3","at AWG conductors for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"screw-type terminals","at ambient temperature 40 °C rated value":"22 A","Apparent holding power of magnet coil at AC":"4.4 V·A","Apparent pick-up power of magnet coil at AC":"27 V·A","Type of voltage of the control supply voltage":"AC","Inductive power factor with closing power of the coil":"0.8","Inductive power factor with the holding power of the coil":"0.27","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","Of The Contactor With Added Electronics-Compatible Auxiliary Switch Block Typical":"5 000 000"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=418173&mlfb=3RT1016-1AL05","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1016-1AL05/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to the 3RT1016-1AL05?","answer":"The 3RT1016-2AP02 is a sibling in the same S00 frame size, but it uses a 24 VAC/DC coil with different coil termination (spring-cage terminals on the coil side). The 3RT1023-1AL20 is a larger S0 frame contactor with higher current ratings.

It mounts on 35 mm DIN rail per EN 50022.

The difference is the coil termination: the 1AL05 uses screw terminals for the coil, while the 2AP02 uses spring-cage terminals. If the panel wiring was terminated for spring-cage, you may need to re-terminate or use ferrule pins for the screw clamp. The main power terminals are screw type on both variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-1AL05","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1016-1AL05 when reusing this data.
