The Siemens 6SL32.0-.YE28-.U.0 is a SINAMICS G120X infrastructure converter rated at 15 kW on a 380-480 V 3 AC supply, sized for HVAC, water, and wastewater applications. It delivers 110% overload for 60 seconds and 100% for 240 seconds — enough headroom for pump start or fan inertia without oversizing the drive.
The 15 kW rating at 380-480 V three-phase sets the motor match: a standard 15 kW 4-pole induction motor on a 400 V line is the intended load. The 110% overload for 60 seconds covers the starting current of a centrifugal pump or the acceleration of a fan — you don't need to oversize the drive for normal starting duty. The unfiltered input means it expects a line reactor or DC choke on the supply side if the installation requires harmonic mitigation; the drive itself doesn't carry an internal EMC filter, so plan for external filtering if the application demands EN 61800-3 Category C2 or C3 compliance. Ambient temperature range of -20 to +45 °C is standard for indoor HVAC plant rooms and water treatment halls. Above 45 °C you'd need to derate per the SINAMICS G120X manual — the spec doesn't list a derating curve, but the 45 °C upper limit is the full-rated point. Size FSC is the mechanical frame; it determines the mounting footprint, gland plate entry, and bus-bar arrangement in the panel.
RoHS compliant since 01-07-06. No UL or CSA mark is listed in the evidence, but the IP20 / UL open type designation indicates the drive is recognized for use in UL-listed panels under open-type conditions.
