That 1500V AC per minute withstand voltage is honestly the first thing that grabs most engineers — it's a solid margin above what you'd expect for a connector rated at 300V DC, and what that means in practice is you've got serious headroom for transient spikes in industrial environments.
So the PA66 UL94-V0 housing isn't just fire-rated, it's also pretty tough against impact and vibration, which matters when you're mounting these on a PCB in a control cabinet that gets bumped around. The CR3+ plated steel screws hold up well against corrosion, and copper alloy terminals give you decent conductivity for that 35A continuous current — but if you're pushing it near the limit for long periods, you'll want to check your ambient temperature because the -40 to 80°C range is wide but derating kicks in above 70°C or so.
12-22 AWG wire range covers most common industrial cable sizes, and the welding termination is straightforward once you've done it a few times — just make sure your iron can handle the heat sink effect form those terminal blocks. The 15.7 Lb/in torque spec for the M4 screws is tighter than some similar connectors, so don't overtighten or you'll strip the threads in the zinc alloy.
Most buyers go with the standard 2-position version for DC power distribution, but we also see orders for custom pin counts if you need more connections — usually 4-6 weeks lead time on those though. We typically stock the standdard model in quantities of 100 pieces or so, and teh MOQ is 50 units for first-time buyers.
