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.
