Compact Small Footprint 1P SWM-100 Mini Circuit Breaker – 10kA Breaking Capacity DIN Rail Mount, Wholesale Available

Most circuit breakers on teh market claim compliance, but getting one that actually holds up under an overload—especially when you're pushing 100A through a line—is a different story, we've had buyers come back to us specifically because the Singi SWM-100 1P doesn't trip prematurely on transient surges like some cheaper units do.

At 10kA breaking capacity, it'll handle serious faults down to that -5°C threshold without failing, while the flame-retardant PA66 housing won't crack or soften under sustained heat (we usually have stock on 63A, 80A, or 100A ratings, but the 125A variant might need a lead time check for orders over 50 units or so).

What it does is fit onto a standerd DIN rail faster than most—firm click on the first try, no bending clips—and the terminal capacity goes up to 50mm² cable, which is better than typical 35mm² you'll see on similar-priced breakers from other suppliers.

Mechanicla life is rated at 20,000 operations, but basically a lot of buyers go with the 80A model for mixed loads because you get that extra headroom over a 63A without jumping to the full 100A frame.

For OEM batches, we offer blank housing or custom labels if you order above 500 pieces (just note tolerances aren't ISO-sorted, so don't use this for hypersensitive tripping applicaion like lab equipment), and CE and ISO9001 paperwork is standard with every pallet.

7-10 days from warehouse for stock items, shipped stacked horizontally with terminal protectors on each unit's screws, and the 10-pack cartons weigh about 2.8kg each—so keep that in mind when estimating freight cost.
