So you've got a panel build coming up and you're spec'ing breakers across multiple amp ratings—I just ordered the L7-63 because of that it covers 1A through 63A in a single model family, which simplifies stocking.

It's AC 230/400V depending on pole count—1P or 2P for the lower voltage, 3P and 4P for 400V application—and it hits the IEC 60898 standard, which is what most commercial and light industiral jobs require these days.

CE certifcation is on teh COA with every batch, and breaking capacity is decent for typical overload and short-circuit protection—though it's not suited for high-fault industrial setups like main breakers in large distribution boards.

What it does well is handle the usual range: 1,2,4,6,10,16,20,25,32,40,50,63A in 1P, 2P, 3P, or 4P configurations, and it's a fixed-installation type with air arc-extinguishing, so no gas handling concerns.

We're seeing a 30-day lead time from factory right now, and shipping is standdard freight—no cold chain, obviously, since it's thermals and contacts, not chemicals.

Anyway, stock is usually available in full pallet quantities, and I've ordered 2,400 units for the upcoming housing project, which should cover the 1P and 2P runs we need.

Frequently Asked Questions

What is the minimum order quantity for the SL7 MCB if I need a mix of different amperages and pole configurations?

We can handle mixed orders, but the MOQ typically starts at 100 pieces total. For specific combos like 4-pole 63A units, just let us know the breakdown and we'll quote accordingly.

How long does it usually take to produce and ship a wholesale order of these L7-63 circuit breakers?

Lead time is roughly 15-25 working days for standard orders, depending on quantity and customization. We'll confirm exact timing once we see your PO.

Do you provide the CE certification documents and test reports for the IEC60898 standard with the shipment?

Yes, we include a CE certificate and the relevant IEC60898 test reports with every batch. Just request them when placing the order.

Can I get the SL7 MCB with a specific breaking capacity rating, or is it fixed at one value?

The breaking capacity is determined by the low voltage design and isn't adjustable per unit. It meets IEC60898 requirements for residential and light commercial use. If you need a higher rating, we'd suggest looking at our industrial series.

What packaging options are available for bulk wholesale orders of these breakers, and can they be stored long-term?

We pack them in standard export cartons, typically 12-24 pieces per box, with individual polybags. They store fine in a dry, ventilated warehouse for years without issues.
