355 kW drive for pump and fan duty — overload profile and mains compatibility
The 6SL3220-3YH58-1CP0 is a SINAMICS G120X infrastructure converter rated 355 kW with an overload capability of 135% for 3 seconds or 110% for 60 seconds, and 100% for 240 seconds — this overload profile matches the starting and transient demands of centrifugal pumps and fans, where the peak torque requirement is brief and the steady-state load stays below the drive's continuous rating. It accepts a 3-phase supply of 500 to 690 V AC at 47-63 Hz and includes a built-in RFI suppression filter for category C3, meaning it can connect directly to industrial IT and TN networks in that voltage range without an external EMC filter for conducted emissions compliance. The drive ships with an Intelligent Operator Panel and IO expansion included as standard, and integrates PROFIBUS DP fieldbus directly on the control board — no separate communication module needed for connection to a Siemens S7-300/400 or third-party PROFIBUS master.
Cabinet integration — size FSH, IP20, and cooling considerations
Housed in size FSH with IP20 degree of protection and UL open type listing, this drive is designed for installation inside a clean, dry electrical enclosure — the IP20 rating means it is not splash-proof, so it must be located away from washdown areas or condensation sources. Ambient temperature range is 0 to +45 °C — above 40 °C the output current must be derated per the SINAMICS G120X manual; for a 355 kW motor at 45 °C ambient, the drive still delivers full rated current without derating, but the cabinet ventilation must move enough air to keep the internal temperature below that ceiling.
Lifecycle and compliance — active production, RoHS, REACH
RoHS compliance is confirmed since 11 March 2020, and the REACH Article 33 duty-to-inform applies due to lead (CAS 7439-92-1) above 0.1% w/w in certain components — the drive carries the required SVHC disclosure documentation for EU regulatory markets. Export control classification is AL: N / ECCN: EAR99H, meaning no special export license is required for most industrial destinations outside embargoed countries — standard EAR99 civil-application classification.
