We see these go into industrial switchboards and motor control centers where you need reliable fault isolation under load—the 250A rating handles most medium-sized distribution panels without breaking a sweat.
It's got a thermo-electromagnetic trip unit, so you're getting both overload protection and instantaneous short-circuit response in one package, and the breaking capacity comes in three variants (L/M/H) depending on how much fault current you're dealing with in your system.
insulation voltage is 800V with a working voltage up to 690V AC at 50Hz, and it's pollution degree 3 which basically means it'll hold up in dusty factory environments without issues—most buyers go with the M type for general industrial use.
Mechanicla life is 20,000 operations and electrical life is 10,000, so it's not meant for frequent switching like a contactor would be, but for a backup disconnect or feeder protection it's pretty much set-and-forget for years.
Lead time is usually 2-4 weeks for standerd orders, but the H type with ultra-high breaking capacty might take a bit longer (check stock). CE and CCC are on the nameplate, so you're covered for both domestic and export installations.
For 100 units of the ASKM1-250A, standard lead time is around 15-20 working days. We can speed that up to 10-12 days if you need it, but that depends on current production load.
Yes, we can share the CE declaration of conformity and CCC certificate with you. We also have routine test reports available for the ASKM1-250A — just ask when you place the order.
No, the breaking capacity is fixed to L/M/H options — those are standard, high, and ultra-high. You pick the one that fits your system’s short-circuit requirements, and we’ll supply it as ordered.
Storage is fine from -25°C to +55°C, as long as it’s dry and free from corrosive gases. Keep it in its original packaging to avoid dust or moisture buildup.
You can mount it either vertically or horizontally — both are fine. Just make sure the operating temperature stays within -5°C to +40°C, and the enclosure allows proper ventilation.
Zippy delivery was the first thing that impressed me. The package arrived well ahead of the estimated schedule, which was a fantastic start. The breaker itself feels incredibly solid and well-made, with a substantial heft and clean, precise molding that speaks to good manufacturing standards. The CE and CCC markings are clearly and professionally stamped, which is crucial for our compliance checks. Communication from the seller was proactive and clear throughout the process, answering my pre-shipment questions promptly. Everything was packaged securely with ample protective material, and all documentation was included. While I haven't installed it into our distribution panel yet for final operational testing, the initial physical inspection and the overall purchasing experience have been thoroughly positive. This level of attention to logistics, apparent product quality, and customer service makes the process smooth and reliable.
