Product description

Siemens 6SE7021-0EA51-Z is the Z order variant of an AC/AC converter from the SIMOVERT MASTERDRIVES Motion Control range. The exact Z suffix identifies a base unit for additional order features; no individual additional identifiers are stated in the bound product record. Siemens documents 3 AC 380–480 V, 50/60 Hz, 10.2 A rated current and 4 kW rated power for the base unit. Protection is IP20. Siemens selection data states complete external dimensions of 90 × 425 × 350 mm in width, height and depth order. A dealer record for exact identifier 6SE7021-0EA51-Z confirms the base unit for additional configurations and states 8.5 kg. Because unspecified additions can alter the weight, it is visibly shown as a conservative estimate of approximately 8.5 kg. This replaces the previous internal 13 kg value. Dimensions and weight refer to the individual base unit without shipping packaging, connection cables or external cabinet components. The complete identifier with -Z remains separate from product 6SE7021-0EA51 without the suffix. Similar variants can contain different assemblies, connection characteristics or weights. Input voltage, frequency, rated current, rated power, protection, construction and order variant are separate assignment characteristics. The three dimensions fully describe the base enclosure. Product type, AC/AC drive type and Z version remain before the closing mechanical rows. Undocumented additional contents are neither added nor asserted. Complete external dimensions and the visibly estimated weight form the final two rows, keeping the base unit and unknown Z configuration transparently separated.

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.
