355 kW at the overload profile that matters for pump and fan loads
The 6SL3220-2YH58-1CP0: The headline rating is 355 kW with a 135% overload for 3 seconds or 110% for 60 seconds and 100% for 240 seconds — this is the duty cycle that matches centrifugal pump and fan starting profiles where the breakaway torque is low but the run-up time can be long. The 110% / 60 s window covers the acceleration ramp for a typical HVAC impeller without oversizing the drive. Input voltage range is 3AC 500-690 V +10/-20% at 47-63 Hz, so it lands on 525 V, 600 V, and 690 V distribution systems common in North American and European industrial and infrastructure sites. The built-in RFI suppression filter is category C3, which means it meets conducted emission limits for industrial environments (second environment) per IEC 61800-3 — no external filter needed for most plant-floor installations.
Fieldbus and I/O — what is onboard and what it saves
PROFIBUS DP is integrated on the control board, so no separate communication module is needed for plants running a PROFIBUS backbone. The IO expansion is also onboard — the Basic Operator Panel (BOP) is included for local parameter access and commissioning without a laptop. The drive is part of the SINAMICS G120X family, which is Siemens' infrastructure converter line purpose-built for HVAC, water, and wastewater applications — not a general-purpose drive repurposed for pump duty. The overload profiles and software functions (PID controller, fire mode, energy-save optimization) are specific to these loads.
Active production — standard sourcing, no LTB clock
RoHS compliance date is 11-03-20. The REACH declaration notes lead (CAS-No. 7439-92-1) above 0.1% w/w — this is a standard disclosure for drives with solder joints and busbars; it does not restrict sale or installation under current REACH regulations.
