Siemens 3WL1340-4EB66-4AN2-Z K07+S01+R 30+R21+P01+R15 Air Circuit Breaker RFQ Guide
Siemens 3WL1340-4EB66-4AN2-Z K07+S01+R 30+R21+P01+R15 is a configured Siemens 3WL air circuit breaker request for low voltage switchgear maintenance and power distribution spare planning. This is a long model string, but the full configuration should stay intact because accessory suffixes and option codes can affect the actual breaker requirement.
Electrical maintenance teams may search this exact Siemens 3WL breaker code when a main incoming panel, switchboard feeder or low voltage distribution cabinet needs a replacement spare. The request may come from a panel drawing, breaker label, switchgear service report or an old purchase record.

| Product type | Siemens 3WL air circuit breaker for low voltage switchgear |
| Buyer role | electrical maintenance team, switchgear contractor or project procurement engineer |
| Documents to send | breaker label, panel drawing, trip unit detail, accessory list and delivery timing |
| Common risk | a nearby 3WL code may look similar but include different suffixes or accessories |
Documents that make the quote clearer
- Clear photo of the existing breaker front label.
- Switchgear panel drawing, feeder reference or old purchasing line.
- Rated current, breaker frame and trip-unit information.
- Accessory notes such as motor operator, auxiliary contacts, interlock or communication options.
- Urgency level: shutdown repair, project commissioning or future warehouse stock.
For urgent maintenance, the quickest route is to send the breaker label, panel photo and delivery city. For a project spare, the better route is to send the approved electrical specification and accessory notes. For distributor stock, the full configured code should still be preserved so nearby Siemens 3WL variants do not get mixed together.
Switchgear application context
- Main incoming breakers for low voltage switchboards
- Feeder protection in plant electrical rooms

When a similar model is not enough
Some breaker inquiries can begin with a series family, but this item should be quoted from the full model string. If the buyer says an equivalent is acceptable, Siemens 3WL1340-4EB66-4AN2-Z K07+S01+R 30+R21+P01+R15 should remain in the RFQ as the baseline for comparison.

Procurement note for configured breaker requests
A configured Siemens breaker request should be handled more carefully than a simple low voltage component inquiry. The buyer may need one unit for urgent replacement, a matched spare for a switchgear room or several breakers for a project. In each case, the full 3WL code and accessory notes help prevent a near-match from being quoted as the requested item.
