We've been shiping these SC65-63 breakers for years now, and what it does is handle overloads and short circuits pretty reliably in residential and commercial setups — the thermal-magnetic trip mechanism is what you're getting, and it's basically the standard for this type of protection.
You can grab it in 1P, 2P, 3P, or 4P configurations, with rated current options form 6A all way up to 63A, and most buyers go with the 10kA breaking capacity because of that it covers most lighting and power distribution needs without overkill. It's rated at 230/400V AC, 50/60Hz, and the housing is flame-retardant PA66 (usually holds up fine in normal operating temps from -5°C to +55°C).
Trip curves B, C, and D are avaliable depending on your load type — curve C is the most common for general circuits, but if you've got motor starts or transformer inrush, curve D handles that better. The mechanical life is about 10,000 operations or so, which is typical for this class, and teh terminal capacity goes up to 25mm² (check your wire gauge before ordering).
it meet IEC60898-1 and GB10963.1 standard, with CE, CB, and CCC certifications — we usually have stock for the popular ratings like 16A, 20A, and 32A, but for 63A or 4-pole versions, confirm lead time (usually 2-4 weeks). One thing we don't recommend is using it for DC circuits or high-inductive loads without checking the specs first.
Anyway, packaging is standard — individual units in boxes or bulk cartons depending on your MOQ, which is typically 50 units or so for mixed poles. The IP20 rating means it's fine for indoor panels but not for wet environments, so keep that in mind.
B curve trips at 3-5 times rated current, good for resistive loads like lighting. C curve trips at 5-10 times, standard for motors and general circuits. D curve trips at 10-20 times, meant for high inrush loads like transformers. Pick based on what you're protecting.
Yes, we include CE, CB, and CCC cert copies with every shipment. Just let your sales rep know you need them, and we'll attach them to the packing list.
MOQ is 100 pieces per pole type, so for 4-pole that's 100 units. If you need a smaller test batch, we can sometimes do 50 pieces — just ask.
Yes, the housing is made from flame-retardant PA66, which self-extinguishes. The protection degree is IP20, so it's safe for indoor use but not waterproof — keep it in a dry panel.
We stick to the standard 6-63A range and 10kA breaking capacity for this model. Custom current ratings aren't available, but we can adjust the trip curve if needed. For different specs, check our SC series.
