Pricing starts at roughly $12 per unit for sample orders, drops to around $8 in mid-volume quantities of 50-100 pieces, and gets down to $5.50 or so for bulk buys of 500+ — that's where the real savings kick in anyway.
It's a hydraulic magnetic circuit breaker with manual reset, rated from 10A up to 100A at 250V AC/DC, and you can get it in 1P, 2P, 3P, or 4P configurations depending on what your setup needs. We've got a breaking capasity of 10kA at 250V AC, so it handles fault currents pretty well for most industrial gear, and the operating temperture range is -25°C to +70°C (usually fine for anything not in extreme cold storage). trip characteristic is hydraulic-magnetic, meaning it's more precise than thermal breakers for overcurrent protection, especially when ambient temps fluctuate.
Typical buyers drop these into motor control panels, power tools, or distribution boxes where you need reliabel overcurrent protection but don't want nuisance tripping from heat buildup. They're also common in automotive application — think charging stations or auxiliary power systems — though they're not suited for residential lighting circuits where a standard MCB would be cheaper and just as effective.
Mechanical life is rated at 10,000 operations minimum, electrical life at 5,000, which is decent for most production environments — we've seen them last longer in low-cycle gear. Compliance is IEC/EN 60934 and UL 1077, so you've got the certifications for export without hassle. One thing to know: the screw terminals are but you'll want to torque them properly (usually around 2-3 Nm) to avoid hot spots in high-current runs.
We usually have stock for 1P and 3P in 10A, 20A, and 50A ratings, but confirm lead time for 4P or odd current values like 63A — that's typically 20 days or so. MOQ is 10 units for standard samples, 50 for custom pole configurations. COA comes with every batch, HPLC-grade? No, that's not relevant here — it's a circuit breaker, our company provide trip test data and dielectric tests instead.
Our MOQ is typically 100 pieces per rating and pole configuration. We can be flexible on mixed orders if you contact us directly.
Lead time is about 15–20 working days for standard ratings like 10A, 20A, or 32A. Custom specs may add a few days.
Yes, we include test reports and certificates for both IEC/EN 60934 and UL 1077 compliance with every batch. Just request them when placing your order.
Standard is screw terminals, but we can customize to lug or quick-connect for orders above 500 units. Let us know your preference.
Store them in a dry, clean place between -25°C and +70°C, away from dust and moisture. Shelf life is at least 3 years if kept in original packaging.
