Was getting tired of chasing down nuisance trips on motor circuits that weren't actually shorting — the 10kA rating on this HG003 will handle inrush without false tripping, and we've got both Type C for lighting and Type D for motors, which is exactly what the electrician asked for.
Rated current spans 6A to 80A, voltge is 230V for single pole or 400V for multi-pole, and it's a fixed embedded insallation so it'll fit right into the existing panel boxes we already have in the field (usually 2-4 weeks lead time on non-standard pole counts). Breaking capacty is either 6kA or 10kA depending on the batch we pick up — most buyers go with the 10kA for that extra headroom.
What it does is handle overload, short circuit, and overvoltage protection, and the SF6 arc-extinguishing medium means it's actually quieter than the air-break units we used before — a small thing but the maintenance crew noticed. Operating temperature is -50°C to +40°C, but honestly, I'd be careful above 2000m altitude; the specs say it's fine, but performnce drops off give or take 10% in my experience.
Basically, it's a fixed embedded MCB with 1P, 2P, 3P, or 4P configurations — the 4P version fits our three-phase distribution boards perfectly, and the cerification is GB10963.1 so no compliance headaches. Also, the instant release types are pretty standard: Type C for lighting loads, Type D for motor starts — we'll order the D type for the compressor bank.
For OEM, they can customize the trip curve slightly but I wouldn't push it below 6A or above 80A — it's a general-purpose breaker after all, not suited for precision electronics where you'd want a dedicated RCD. MOQ on the custom stuff is 50 units or so, but we'll stick with the standard 4P 10kA Type D for now.
So we'll place an order for 60 units of the HG003 in 4-pole, 10kA, Type D, rated at 32A for the motor circuits — just confirm lead time on that specific variant since we usually have stock, but I'd rather be safe. No point in overcomplicating it when the specs match the install requirement exactly.
MOQ is typically 50 units for the 4-pole version, but we can do smaller trial orders if you're just testing. Just reach out.
Standard lead time is 15-20 working days after order confirmation. Rush orders can be expedited to 10 days for an extra fee.
Yes, we include a test report and a copy of the GB10963.1 certification with every batch. You'll get the full docs in the package.
Absolutely—it's rated from 6A to 80A, so we can set it to 63A or 80A on request. Just specify when you order.
Keep it in a dry, clean place at -50°C to +40°C, away from moisture and dust. Use the original packaging if possible.
