We've been getting a lot of requests from contractors lately who are tired of nuisance tripping on lighting circuits that have a sudden inrush spike—it's the kind of problem you don't notice until the whole floor goes dark during a test.

The 6A 4P version here hits a nice balance for three-phase commercial panels where you're protecting a split load, and the 10kA breaking capasity gives you real headroom against bolted faults in a sub-distribution board without overspending on an indutrial unit.

Basically, this handles both overload and short circuit through a bimetal strip and an electromagnetic coil—standard stuff, but the arc-extinguishing chamber is actually better cut than most at this price point, so the 6,000 operations claim feels conservative.
You'll get it with a COA from our latest batch (HPLC verified at batch purity, though we usually have stock on the 6A version) and it ships in a 30-piece carton, each breaker sealed in its own PVC sleeve with the techncial label on the side.

The flame-retardant PA66 case (it's a V-0 rated nylon) handles ambient temps from -5°C to +55°C alright, so borderline roof voids or unventilated switch rooms won't cause premature tripping—at least not more than any other air-cut breaker would.

We tested a batch recently and the 4P unit comes fully assembled with all three phase poles and a neutral, so you don't need to faff around with linking bars for most distribution boards; DIN rail clip is a solid spring-latch type we've had zero returns on for about two years or so.
Our MOQ for the SC65-63 varies by quantity, but for the 4P 6A model, we typically start at 100 pieces. If you need less, let us know and we can check stock availability.
Yes, we have CE, CB, ISO9001, and CCC certifications for this MCB. We can share copies of the test reports and certificates upon request.
Absolutely, we offer B, C, and D curves for the SC65-63. Just specify the curve type when ordering, and we'll ship the right version.
Standard orders usually ship within 15-20 days. For custom configurations, it might take a bit longer, around 25-30 days, depending on the quantity.
Keep it in its original packaging in a dry, clean place at -5°C to +55°C. Since it's IP20 rated, avoid dusty or damp environments to keep the terminals clean.
