90 kW at 400 V — what the AC-3 rating means for motor sizing
The 3RA2110-0DE15-1AP0: The 90 kW at 400 V AC-3 rating defines the maximum three-phase induction motor this starter can switch under full-load starting conditions. AC-3 duty covers starting and plugging of squirrel-cage motors — the contacts make and break the locked-rotor current, which is typically 6–8× the full-load current. The 0.32 A at AC-3 400 V is the motor full-load current at that voltage; the starter's thermal overload relay is set to this value. This protects standard IEC motors during a stalled-rotor condition without nuisance tripping on normal acceleration. For motors with longer start times (high-inertia loads like fans or centrifuges), a CLASS 20 or CLASS 30 trip class would be required — this unit is not suited for those applications.
Panel fit — S00 frame, 45 mm width, DIN-rail snap-on
The S00 size feeder and 45 mm width mean this starter occupies a single 45 mm slot on 35 mm DIN rail. The mounting method is screw and snap-on — the DIN-rail clip engages with an audible click, and the screw provides positive retention against vibration. Vertical mounting position is specified; horizontal mounting would affect the thermal calibration of the overload relay. Depth is 97 mm, height 198 mm. The required clearances around the unit are: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards. These are the minimum air gaps for heat dissipation and arc flash containment — a panel layout must respect them to maintain the UL/IEC ratings. This reduces wiring time on the panel assembly line and eliminates the risk of screw-terminal loosening under thermal cycling.
Supplied as an integrated assembly — contactor and link module included
This order code ships as a complete direct-on-line starter, not a kit of loose components. The supplied contactor is 3RT2015-2AP01, and the supplied link module is 3RA2911-2AA00. The link module provides the mechanical and electrical interconnection between the circuit-breaker (or fuse base) and the contactor — no additional wiring between the overload relay and contactor coil is needed. The circuit-breaker size is also S00, matching the feeder frame. This allows a coordinated short-circuit protection assembly (Type 2 coordination per IEC 60947-4-1) when paired with the correct Siemens circuit-breaker from the same S00 family. For MRO spares planning, the contactor and link module are orderable separately if only one component fails.
Lifecycle and compliance — active production, RoHS dated
The substance prohibitance date is 10/01/2009, which aligns with the original EU RoHS directive (2002/95/EC) compliance cutoff. For REACH and UKCA declarations, the manufacturer's current compliance documentation should be requested at order — the prohibitance date confirms the design predates the 2011 RoHS recast but does not guarantee compliance with later amendments without a current declaration. Operating temperature range is -20 to +60 °C, storage and transport range is -50 to +80 °C. These are the environmental limits for warranty coverage — the starter must not be operated outside the -20 to +60 °C window, even if the storage limits are wider.
