Rated form 6A up to 63A depending on your setup, so you can match it to whatever circuit load you're dealing with — we stock these in B, C, and D tripping curves for different starting currents. The housing is flame-retardant PA66, which basically means it won't contribute to a fire if something goes wrong, and it clips onto standard 35mm DIN rail (usually takes about 10 minutes to install for a single pole). 2. It's got a mechanical life of 10,000 operations, give or take, which is pretty standerd for this class of breaker — not the highest we've seen, but fine for most residential and light industrial use. The IP20 rating means it's not for wet areas, so don't put one outdoors unless it's inside a sealed enclosure. 3. We carry 1P, 2P, 3P, 4P, and 1P+N configurations, and the terminal can take up to 25mm² cable — that's enough for most branch circuits you'd run. breaking capasity is either 4kA or 6kA depending on the variant, and honestly, for a 230V residential panel, 6kA is usually plenty. 4. it meet IEC60898, CE, CB, and CCC standard, so you can show the certs to your inspector or client without any pushback. We've been shiping these for a few years now — one thing you'll notice is the residual current options are 30mA, 100mA, or 300mA, so pick the right one for your fault protection needs (30mA for personnel protection, 300mA for fire prevention). 5. The storage temp range is -25°C to +70°C, which matters if you're warehousing these in an unheated space over winter. Each pole weighs about 0.15kg, so a 4-pole unit is roughly 0.6kg — easy to handle but don't drop it, the internal mechanism can be finicky if the case cracks. 6. Also, the operating temperature range is -5°C to +40°C, so it's not suited for extreme cold environments like an uninsulated freezer room — you'd need a different rated breaker for that. We usually have stock on the common ratings (16A, 20A, 32A C-curve) but lead time on odd ones like 6A or 63A can be 2-3 weeks.

Frequently Asked Questions

What is the minimum order quantity for the SG65LE-63 MCB?

We typically require an MOQ of 100 pieces per model, but for trial orders we can go down to 50. Let us know the pole count and rated current you need.

Do you provide CB certification documents with the shipment?

Yes, each batch comes with a CB test report and certificate. We also include IEC60898 compliance docs and can issue a certificate of conformity on request.

Can I get a custom tripping characteristic like B or D for the 1P+N version?

Sure, the 1P+N pole is available with B, C, or D curves, same as the other poles. Just specify your preference when ordering.

What's the recommended packaging for long-term storage of these breakers?

We ship them in sealed polybags inside corrugated cartons. For storage, keep them in a dry place at -25°C to +70°C and avoid stacking more than 5 cartons high.

Are the terminals rated for 25mm² wire on all pole configurations?

Yes, the terminal capacity is 25mm² across 1P, 2P, 3P, 4P, and 1P+N. That covers most residential and light industrial wiring needs.
