315 kW VFD for HVAC and water infrastructure
The Siemens 6SL3220-3YH56-1CB0 is a SINAMICS G120X infrastructure converter rated at 315 kW with a 135% overload for 3 seconds or 110% for 60 seconds, and 100% for 240 seconds — the overload profile matches the starting and intermittent duty of large centrifugal pumps and fans in HVAC, water, and wastewater plants. It operates on 3AC 500-690 V +10/-20% at 47-63 Hz, with an integrated RFI suppression filter for category C3, meaning it meets conducted emission limits for industrial power networks without an external filter in most installations. The drive includes an intelligent operator panel and IO expansion, with MODBUS RTU and BACnet MS/TP fieldbus onboard — no additional communication module needed for building management system integration.
Active production — BOM-ready sourcing
The part is classified as product class C — manufactured or produced to order, which means it is built against a confirmed order rather than held as off-the-shelf stock; lead time and pricing are confirmed at RFQ against the BOM quantity. Packaging dimensions are 800 x 1870 x 600 mm — factor this into freight planning for the FSH frame size.
Compliance and regulatory documentation
RoHS compliant since March 2020, with a REACH Article 33 declaration for lead (CAS 7439-92-1) above 0.1% w/w — the lead content is in certain electronic components and does not affect the drive's suitability for EU or UKCA markets. Export control classification is AL: N / ECCN: 9N9999, meaning no special license is required for most industrial end-uses.
