You're wiring up a distribution panel for a small factory line or a commercial building, and what you need is a breaker that reliably trips on overload without nuisance tripping—basically, it's the DZ15 series, covering 10A all the way up to 100A in common steps like 16, 25, 40, 63, and so on. The inverse-time curve means it'll handle startup surges from motors or transformers, but it won't hold indefinitely at 1.05 times rated current (usually no trip within an hour, but it's not adjustable). We've got these in 1-pole, 2-pole, 3-pole, and 4-pole configurations, and they're fixed-mount only—no plug-in base here.
Breaking capacity sits at 3000A for the smaller frames and 5000A for the 100A unit, which is fine for most commercial secondary distribution but don't expect it to clear a massive fault at the main service entrance. Contact material is silver zinc oxide (AgZnO), so arcing damage is pretty minimal over time, and electrcial life is rated at 10,000 operations—though only 1,500 of those are at full rated load voltage. The arc extinguishes in air, so there's no gas or vacuum chamber to worry about; it's just a rugged molded case.
One thing we've noticed handling these is the oil-damped hydraulic release mechanism—it gives a smoother trip curve than thermal-only breakers, especially in variable ambient temps. Operating frequency maxes out at 120 operations per hour, so don't cycle it like a switch for rapid on/off testing. Ambient range is -5°C to +40°C for operation, storage can go down to -25°C and up to +70°C, but if you're pushing the lower end, hydraulic delay will stretch a bit.
Also, we carry the DZ15-40, DZ15-63, and DZ15-100 models, and the current ratings available are 6, 10, 16, 20, 25, 32, 40, 50, 63, 80, and 100A—though the 6A and 10A are less common, so confirm stock if you need those. Packaging is typically in individual boxes, 10 pieces per carton, and we can include a COA with each batch if you request it at order time. MOQ is usually 20 units or so, but our company can do less for repeat buyers.
It's not suited for DC circuits or high-frequency switching application—the arc extinction is designed for 50/60Hz AC only. Certification-wise, it carries ISO9001, CCC, CE, and CB marks, so it'll pass most inspection requirement for export or domestic use. One detail that catches people: the storage temperture spec is wider than the operating range, so if you're warehousing these in an unheated space, you're fine as long as you let them acclimate before insallation.
The DZ15 series covers 10A to 100A, with specific options at 6, 10, 16, 20, 25, 32, 40, 50, 63, 80, and 100 amps. So you can pick the exact rating that matches your load.
We typically require a minimum order of 50 pieces per model and pole configuration. For larger quantities, we can discuss better pricing.
Yes, the DZ15 series comes with ISO9001, CCC, CE, and CB certifications. We can include copies of the certificates with your shipment.
Lead time is usually 15–20 working days for standard orders. If you need a rush, we can expedite for a small fee, depending on stock availability.
It's designed for indoor use with an ambient range of -5°C to +40°C. For storage, it can handle -25°C to +70°C, but avoid direct exposure to moisture or extreme heat during operation.
