We've been shipping these DC breakers for solar setups a while now, and what it does is handle the high-voltage DC side of things pretty well — up to 1000V in 3-pole or 4-pole configurations, which most buyers don't realize until they check the specs against their string voltages.
The 10kA breaking capasity is actually the key number here, because with larger arrays you can get some serious fault current potential; we usually recommend the 10kA version for commercial-scale PV systems where the short-circuit current might exceed 6kA.
Thermal magnetic tripping with B or C curves gives you flexibility depending on the load type, but it's not really suited for sensitive electronics or constant inrush loads like motor drives — it's a workhorse breaker for solar combiner boxes and battery circuits.
You'll see the AS 60947.3 and IEC 60947.2 certifications right on the side of the unit, and we batch-test every run with HPLC-grade verification on the trip characteristics, so teh tolerances are tighter than what you'd get form a generic import.
Lead time is usually 20 days or so for standerd quantities up to 200 units, but our company can do custom labeling if you need your branding on the transparent cover — just let us know the logo size so it doesn't obscure the ON-OFF indicator.
One thing we've noticed from handling these is the IP40 rating on the body means it's fine for indoor panels but you'll want a weatherproof enclosure for outdoor combiner boxes, since wiring ports are only IP20.
The MOQ for the EDB1-63 series is typically 100 units per pole configuration. For a 4P unit, that means you'd be looking at 100 pieces, but we can be flexible on smaller trial orders—just ask your sales contact.
Yes, we include copies of both certifications with every order. Just let your account manager know you need them, and we'll make sure they're in the packing list.
For 500 units of the 2P EDB1-63, lead time is typically 15-20 working days. If you need it faster, we can sometimes rush it to 10-12 days for a small surcharge.
Not exactly. The 10kA Icu is valid for the higher current ratings (32A-63A) at 1000V DC. For lower currents like 10A-20A, the breaking capacity is 6kA at that voltage. Check the datasheet for the full curve.
Store them in a clean, dry place within the -40°C to 85°C range. Keep them in their original packaging to avoid dust or moisture, and don't stack heavy items on top—those DIN rail clips are sturdy but not indestructible.
