We've been seeing these go into panel builds where the 1000V insulation rating actually matters for the system voltge rating, especially in with higher harmonics or transient spikes that could stress standard 690V rated gear—the arc chamber does a decent job of quenching, though with 36kA at 400V you'll want to be sure your fault current is within that range, not pushing it at the top end.
The mechancial life is 8,500 operations, which is pretty much what you'd expect for a fixed-mount MCCB in a distribution board where it's not cycled daily; the electrcial life at 1,500 operations means it's better suited for backup protection rather than frequent switching duty, so if you're planning to use it as a motor starter's primary disconnect, that's not really intended use case.
What it does is handle 25A to 160A in 2P, 3P, or 4P configurations, and teh terminal box is included—no extra parts to source for your busbar connections, which saves some headache on assembly. BMC flame retardant base gives you that extra margin if you're in an environment with higher ambient temps, but keep the operating range between -5°C and +40°C; we usually have stock on the 100A and 160A frames, but confirm lead time for odd current ratings or DC versions.
For DC application, it's rated at 250V or 1000V depending on the pole configuration, which is about what you'd expect given the arc extinguishing design; the 2000m altitude limit is one detail buyers sometimes overlook—if you're working at higher elevations, the dielectric strength drops, so derate accordingly or pick a different breaker.
It's got CE, CB, CCC, and RoHS certifications, so it'll clear most compliance checks without extra paperwork; the storage temperature range of -25°C to +70°C is generous for warehouse conditions, but that ≤95% relative humidity at 40°C is the real limiting factor—don't leave it in a damp basement unheated over winter.
Our MOQ for the DAM3-160 is 10 units per pole configuration, but we can sometimes accommodate smaller orders depending on stock.
Typical lead time is 15-20 working days after order confirmation, though it may vary based on the quantity and pole configuration.
Yes, it’s certified with CE, CB, CCC, and RoHS, so you’re covered for most international and Chinese market requirements.
For AC, it handles 400V or 690V, while DC goes up to 250V or 1000V depending on the circuit—just make sure your application matches the specific voltage rating.
It can handle storage from -25°C to +70°C and humidity up to 95% at 40°C, so it’s fine in most warehouses, but avoid long-term exposure to condensation.
