Customization is actually where this line shines — our company can tweak the packaging, labeling, or even trim characteristics if you're ordering enough volume, usually 500 units or so, and that's how most buyers get exactly what they need without overpaying for specs they don't require, like the 4-pole version for a single-phase job (check your board layout first).

But if you just need a stock run, the standard 1A through 63A range covers most residential and light commerical panels, and we've found the B-curve works best for general lighting circuits while C-curve handles motor loads better — basically match teh trip type to your worst-case inrush, not the steady-state draw.

It's certified to both IEC/EN60898 and IEC/EN60947-2, which is pretty much the for this class, and every batch ships with a COA from our in-house lab, though we usually have stock ready but confirm lead time before locking in a big order — also, the 4500A breaking capacity typically suits domestic sub-distribution but isn't suited for heavy industiral mains where you'd need something in the 10kA range.

One detail that's easy to overlook is the visible contact position indicator on the front — it's a small gray-green flag that shifts when the breaker trips, which saves you having to wiggle the handle to check if it's actually open or just off, and that matters a lot when you're troubleshooting a busy panel at 2 AM.

We don't hide limits: mechanical life is 10,000 operations and electricla is 4,000, which is typical for this price point, and while the IP20 rating means it's fine inside a clean panel, don't mount it anywhere exposed to dust or moisture without an enclosure — anyway, the 35mm DIN rail clip is solid, no slop once snapped on.

Frequently Asked Questions

What is the minimum order quantity for the GDC1-63 MCB?

Our standard MOQ for this model is 100 pieces per pole configuration. We can discuss smaller trial orders if you're just getting started.

Do you provide the CE and CB certification documents with the shipment?

Yes, we include copies of CE, CB, and RoHS certificates with every order. Just let your sales contact know if you need the originals or notarized versions.

What is the lead time for a 1P 32A B-curve GDC1-63 in bulk?

Lead time is typically 15–20 working days after order confirmation and deposit. For urgent orders, we can sometimes ship within 10 days if stock is available.

Can the MCB handle a 50Hz system only, or is 60Hz fine too?

It's rated for both 50Hz and 60Hz, so you're covered regardless of your local grid frequency. No derating needed when switching between them.

How should the GDC1-63 be stored if not installed right away?

Keep it in its original packaging in a dry, clean place with temperatures between -25°C and +70°C. Avoid direct sunlight and high humidity to protect the IP20 rated housing.
