What the overload ratings mean for a pump or conveyor
The 6SL3225-0BE31-8UA0 is a SINAMICS G120 Power Module PM250 rated for 18.5 kW under high overload (HO) and 22 kW under light overload (LO). HO duty delivers 200 % current for 3 seconds and 150 % for 57 seconds — enough to start a loaded conveyor or break away a stuck pump impeller without tripping. LO duty gives 150 % for 3 seconds and 110 % for 57 seconds, sized for variable-torque loads like fans and centrifugal pumps where the starting torque requirement is lower. The PM250 supports regenerative operation — it can return braking energy to the line rather than dumping it as heat into a braking resistor, which matters for overhauling loads like centrifuges, hoists, or unwinding sections.
Active production, made to order
The product class is C, meaning it is manufactured or produced to order and cannot be reused or returned against credit — plan the BOM quantity accordingly and confirm lead time at RFQ. Packaging dimensions are 510 x 400 x 310 mm; the unit ships as a single piece.
Regulatory and compliance notes
RoHS compliant since 2016-05-11, with a REACH Article 33 duty-to-inform declaration for lead (CAS 7439-92-1) above 0.1 % w/w. Export control classification is AL: N / ECCN: 9N9999 — no special license required for most destinations, but confirm against your end-use and jurisdiction.
