Product description

Siemens 6SE7021-0EA51 is an AC/AC converter from the SIMOVERT MASTERDRIVES Motion Control range in compact construction. The Siemens compendium assigns the complete order number to a 10.2 A current class. Selection data states 3 AC 380–480 V, 50/60 Hz and 4 kW rated power. The base unit has IP20 protection. Complete external dimensions of 90 × 425 × 350 mm in width, height and depth order and a unit weight of 8.5 kg are documented for mechanical assignment. These values apply to the individual base unit without shipping packaging, connection cables or external cabinet components. The previous internal weight value of 13 kg is therefore replaced by the variant-specific Siemens catalog value. Complete identifier 6SE7021-0EA51 is decisive for product identity; the broad 6SE70 family designation is insufficient. Adjacent type numbers can have different current classes, enclosure widths, power ratings or terminal positions. Input voltage, mains frequency, rated current, rated power, protection and construction form separate technical comparison characteristics. The three external dimensions fully describe the enclosure and separate width, height and depth. Weight is recorded as an individual unit value rather than shipping weight. Product type, AC/AC drive type and assignment to MASTERDRIVES Motion Control remain as device-related data. Values are not transferred to variants with additional option codes. Complete external dimensions followed by exact unit weight form the mandatory final two specification rows, clearly assigning the corrected mechanical core data to Siemens 6SE7021-0EA51.

What applies if an item develops a defect within 14 days?

For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.

In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.

Which shipping methods and delivery times are available?

The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.

A delivery date is binding only if we expressly confirm it as binding.

Which payment terms apply?

The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.

International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.

Can I return an item ordered incorrectly or found incompatible?

No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.

Can I request individual pricing for several items?

You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.
