For sample quantities it's around $45 to $85 depending on the pole count and breaking capacity, mid-range orders of 50 units or so drop to about $30 to $55 each, and bulk buys of 500+ can get you down to $22 to $40 per unit — basically the price scales pretty aggressively with volume.
These are for indutrial power distribution where you need relaible overload and short-circuit protection, and we've seen them used in factory floor panels, marine switchboards, and even some solar farm combiner boxes, though they're not ideal for high-altitude installations above 2000m or extreme temperatures outside -5°C to +40°C.
The DAM2 series handles up to 690V AC with an 800V insulation rating, and what it does is provide thermal-magnetic or electromagnetic trip characteristics depending on your appliction — the L type has a lower breaking capacity for general use, M is the mid-range workhorse, and H handles the heavy fault currents, and you can get them in 2P, 3P, or 4P configurations from 63A all the way up to 1250A.
Actually, one thing most buyers don't think to ask is that the arc chamber design in these breakers is pretty effective at quenching arcs quickly, which means less wear on the contacts over time — we've had customers report consistent performance after thousands of operations, and the fixed mounting is straightforward for panel builders.
We usually stock the more common ratings like 100A, 250A, and 630A in 3P and 4P with M-type breaking capacity, but for the H-type or odd current values like 800A or 1250A you'll need to confirm lead time (usually 20 days or so for custom orders), and we can add shunt releases, UV releases, or auxiliary contacts as needed.
The cost-effectiveness comes from the fact that these meet IEC60947-2 standdard without the premium price tag of European brands, and we've been supplying them to OEMs for roughly seven years now — the tolerances are tighter than generic Asian imports, and our company provide COA with every batch, though you'll want to check the TDS for your specific voltage requirement.
L, M, and H refer to low, medium, and high breaking capacities. Your choice depends on the fault current level at your installation site — check the short-circuit rating of your system, and we'll match the right type.
Yes, 2P is also available — the specs list 2P, 3P, and 4P options. Just specify the pole count when you place your OEM order.
MOQ typically starts at 50 units for standard configurations, but for custom combos with shunt releases or UV releases, it can go to 100. Let me know your exact spec, and I'll confirm.
Absolutely — full IEC60947-2 type test reports and certificates are available upon request. We can share them with your order confirmation.
The operating range is -5°C to +40°C, but for storage, we recommend -25°C to +55°C. Keep them in a dry place, and avoid stacking heavy loads on the packaging.
