We run each batch through a full test cycle before it leaves the workshop — overload and short-circuit trip testing at 10In±20% is standard, and we've got the COA, though you'll want to confirm the Ics rating of 18kA matches your downstream coordination needs, as the 22kA Icu is the ultimate limit but service breaking is what matters in daily use.
The 63A rating at 400V AC is pretty much the workhorse for smaller indutrial panels or sub-distribution boards, and the 4P configuration covers all phases plus neutral, which is what most buyers go with for three-phase systems where you need full isolation.
It's CE and CCC certified, so compliance with IEC standard is there, but what you don't always see on the spec sheet is that we do a retest on any returned unit within 30 days — we'll check the trip curve and insulation resistnce at 800V before we issue a replacement or refund, and that's something we've had to do maybe three times in the last year.
Dimnesions are 78 by 76 by 136mm — it's compact enough to fit in a standard enclosure, but the screw terminals need a proper torque driver (usually 2.5 to 3.5 Nm) or you'll get nuisance tripping form loose connections, and the ambient temperture range of -5°C to +40°C means it's not suited for outdoor installations in freezing climates without a heater.
Lead time is typically 15 to 20 working days or so for a standard order of 50 units, but if you need a faster turnaround, we can sometimes pull from stock — just confirm availability before you place the PO.
The ultimate breaking capacity (Icu) is 22kA, and the service breaking capacity (Ics) is 18kA for the L type. That means it can safely handle up to 22kA of fault current without damage.
Yes, it holds CE, CCC, and ISO9001 certifications. So it's compliant with international safety and quality standards for industrial use.
Typically, our MOQ is 10 pieces, but we can discuss smaller orders depending on stock. Just let us know your quantity.
The breaker trips instantly when the current hits 10 times the rated current (63A), so around 630A, with a tolerance of ±20%. It's designed for quick overload and short-circuit protection.
You can store it between -25°C and +70°C. For active use, it works best from -5°C to +40°C.
Lately, I received the ASKM1-63A 4P Molded Case Circuit Breaker, and I must say the shipping was incredibly fast and reliable. The package arrived ahead of schedule, which was a pleasant surprise, and everything was securely packed without any damage. As for the quality, the circuit breaker feels robust and well-made, with solid construction that gives me confidence in its durability for industrial settings. The service from the seller was outstanding too; they were responsive and helpful throughout the process, answering all my queries promptly. Overall, a very satisfying experience that I'd happily recommend to others.
