You're looking at 10kA breaking capacity in a DC circuit breaker that fits a standard DIN rail—that's teh kind of margin you need when an EV charger arc flash turns into a real problem, and we've seen systems where anything less would have welded contacts and fried the downstream converter.
The thermal-magnetic trip on these B/C type units kicks in fast enough to protect sensitive electronics, but we usually stock the 10A to 63A range because most buyers go with 32A or 40A for Level 2 charging stations, and the 2P or 4P pole version handles the voltage doubling you'll need for 1000V setups.
Basically, it's IP40 at wiring port but IP66 rated overall—so it'll take a hose-down in a parking lot insallation, and the 2.5-25mm² terminals give you room for thicker cables without that annoying stripped-thread fight. Check lead time on the 3P and 4P options though (usually 2-4 weeks for non-standard combos).
What it does is ride through normal loads at -30°C to +70°C without nuisance tripping, which pretty much rules out the cheap breakers that drift with temperature and cause false shutdowns in direct sun. Electrical life is 2000 cycles, mechanical life is 20,000—not great for daily switching but fine for backup protection.
18mm per pole width means it's compact enough to stuff four poles into the same space as three generic units, and the weight form 125g (1P) to 501g (4P) gives you a feel for the copper mass inside.
Anyway, the 1P at 250V is fine for small battery banks, but for EV charging you'll want the 2P at 500V or 4P at 1000V—the AS 60947.3 compliance is what matters for Australian installations, and we have COAs but make sure your spec requires the specific trip curve.
We usually require a minimum of 100 units per pole configuration, but we can negotiate smaller trial orders for first-time buyers.
Yes, we can provide test reports and certificates confirming compliance with IEC 60947.2 and AS 60947.3 standards—just request them with your order.
We offer standard B and C trip curves and rated currents from 10A to 63A, but custom ratings or curves require a minimum order of 500 units per batch.
Lead time is usually 15-20 working days for stock configurations, including 2P and 4P, but can extend to 30 days for larger quantities or non-standard specs.
The unit itself is IP66 rated, but the wiring port is IP20—so you'll need to seal the connections properly in an outdoor enclosure to maintain overall protection.
