Say your customer's setting up a new distribution board for a small factory floor — that's where this goes, handling branch circuit protection for motors or lighting panels with overload and short-circuit cutoff, and we've seen it work well for rental power skids too where reliability matters more than frills.
Rated from 6A all the way up to 1250A at 690V AC, so you can cover a pretty wide range of loads with one series, and the breaking capasity hits up to 100kA depending on which version you pick — the L-type or M-type are the most common orders we see for commercial builds.
It's thermal-magnetic with that inverse time lag, so nuisance tripping from motor inrush is less of an issue than with a plain thermal breaker, and you get under-voltage protection as a standard feature which some buyers don't realize until they're writing specs.
We usually have the 3P and 4P in stock for the 100A to 630A range, but the 2P and anything above 630A might need a 30-day lead or so — check before you quote, especially if you need marine cerification because that adds a week typically.
Basically, the arc quenching is air-based, not vacuum or SF6, so it's fine for general distribution but don't push it for high-frequency switching applicaion where contact erosion becomes an issue — it's better than a lot of commodity breakers but not a specialized switch.
Polycarbonate housing holds up to -5°C to +40°C for land use (or +45°C for marine), and mechancial life is roughly 10,000 to 20,000 operations depending on the frame size — smaller ones tend to wear faster, so factor that into maintenance cycles.
You can order any rating in the 6A to 1250A range — we don't restrict you to a few standard sizes. Just tell us the exact current you need, and we'll set the trip unit accordingly.
We supply CE, CB, and ISO9001 certs with every unit, and the SWM1 is fully compliant with IEC60947-2 and GB14048.2. If you need a specific test report or factory inspection doc, just ask and we'll include it in the shipment.
For first-time orders or samples, we can go as low as 10 pieces per model. Once you're ready for bulk, MOQ is typically 100 pieces per rating, but we can be flexible depending on the mix.
Yes, you can mount it vertically or horizontally — no need to derate the current. Just make sure the ambient temperature stays within -5°C to +40°C for land use, or -5°C to +45°C for marine environments.
Electrical life ranges from 2000 to 7000 operations depending on the model, and mechanical life is 10000 to 20000 operations. For typical power distribution, that means you won't need to replace the breaker for years under normal switching and fault clearing.
