When your client's solar array feeds a telecom tower in a remote area, this breaker handles the DC side fault without nuisance tripping — we've seen it perform well on 48V battery banks too.
The WSB9Z-80 runs on a fully automatic line, so you're getting consistent weld qualiy on the bimetal strip, which matters for the 10kA breaking capacty at 1000VDC.
It's available in 1P through 4P, and most buyers go with the 2P for photovoltaic combiners, though the 4P version handles split-phase DC systems pretty well.
4, we offer it in 6A to 80A, all C-curve (usually the default for lighting and moderate motor loads), and insulating voltge sits at 1000V with impulse rated at 4kV.
Our typical lead time is about 20 days or so for a standerd 50-unit OEM order, but we usually have stock on teh 10A and 16A ratings if you need a rush.
One thing it's not great for is heavy inductive loads like large DC motors — the C-curve isn't fast enough there, so you'd want a B or D curve for that.
The WSB9Z-80 covers rated currents from 6A up to 80A, so you can pick the exact amperage for your DC circuit protection needs.
Yes, we have ISO9001-2000, CE, CB, and CCC certifications for this model. We can include copies of the certificates with your order.
Our MOQ for OEM orders is typically 500 pieces per specification, but for ODM we can negotiate based on your design requirements. Just let us know the quantity you're looking at.
Lead time for ODM orders is usually 25 to 35 days after sample approval, depending on the complexity of your customization and current production schedule.
It uses air as the arc-extinguishing medium, which is standard for DC MCBs. The internal arc chamber cools and splits the arc to safely extinguish it during a fault, keeping your system protected.
