Drive rating and what it means for your load
The 6SL3220-3YH36-0AB0 is a SINAMICS G120X drive rated for 37 kW output power at 110% overload for 60 seconds and 100% continuous for 240 seconds — the overload profile suits centrifugal pump and fan loads where peak torque is brief and infrequent, not constant-torque conveyor or extruder duty. Input voltage range is 500-690 VAC 3-phase plus 10% / minus 20% at 47-63 Hz, so it lands squarely on 575 V and 690 V nominal industrial grids common in North American and European heavy process plants.
Fieldbus and filter integration
Built-in MODBUS RTU and BACnet MS/TP on the RS-485 port means no separate communication module is needed for building automation or plant SCADA — the drive appears as a BACnet device on the MS/TP trunk, reducing BOM count and panel wiring. The integrated radio interference suppression filter meets category C2 for 500-690 VAC supplies, which covers conducted emissions limits for most industrial and commercial installations without an external filter.
Panel fit and environmental rating
Frame size FSD with IP20 / UL open type protection — the drive is intended for enclosure mounting where the cabinet provides the environmental seal; the IP20 rating means it is touch-safe but not washdown-rated, so keep it out of hose-down zones. Ambient temperature range is -20 to +45 °C, which covers most unconditioned electrical rooms and outdoor cabinets in temperate climates; above 45 °C derating applies per the SINAMICS G120X manual.
Lifecycle and compliance
RoHS compliant since 01 July 2006 and REACH candidate-list declared — the compliance documentation covers EU substance restrictions for cross-border procurement.
