He took a look at our existing distribution setup and immediately saw where this would fit, basically solving the panel space issue without requiring a full redesign of the cabinet layout.
We've been running the 400A frame on a 3-pole configuration for about six months now, and what it does in practice is eliminate the nuisance tripping we used to get from ambient heat in the summer—the -35°C to +70°C operating range handles the warehose extremes, and the 70kA breaking capacty at 415V covers our larger motor loads without needing fuses upstream.
The 0mm arcing distance is one of those specs that buyers don't always ask about upfront, but it matters a lot when you're installing in tight cabinets where you can't maintain traditional clearance; it's actually a different design approach than what you'll see from most European manufacturers.
For ordering, we usually keep the 250A, 400A, and 630A frames in stock, but the 4-pole versions typically have a lead time of 20 days or so because they move fewer units—just confirm with us before committing to a project timeline, as the thermal-magnetic release calibration can vary between the 125A and 630A frames.
One detail that caught me off guard early on: mechanical life is rated at 10,000 to 20,000 operations, but in high-cycle applicaion like a conveyor system that switches multiple times a day, you'll want to check the electricla life of 5,000 to 8,000 operations instead, since that's the real limiting factor for maintenance intervals.
Anyway, the CCC and TUV approvals mean it's good for export to most markets, though if you're feeding a critical process line with sensitive electronics, it's better suited for branch circuit protection than for direct motor control—you'd want a dedicated starter for that.
Our MOQ for the SRM6 series is 50 units per model, but we can negotiate smaller quantities for trial orders or special projects.
Typical lead time is 25–30 working days after deposit, depending on current production load. We can expedite if you're in a rush — just let us know.
Yes, we supply the CB and TUV certificates and test reports as part of the documentation package. You can also request factory inspection reports for full traceability.
The SRM6 series is fixed at Icu=70kA and Ics=50kA for all models. If you need a lower breaking capacity, we'd recommend checking our SRM5 series instead.
Store them in a dry, ventilated area between -35°C and +70°C. Each breaker comes in an individual carton with foam inserts, then packed in sealed plywood cases for export.
