Key Features of Our Cast Brass Drop-Out Fuse Parts
1. Superior Electrical Conductivity
Electrical-grade brass alloy (e.g. CuZn30, 27~30% IACS), ensures stable current transmission, avoids overheating failure for overhead power lines.
2. Outdoor Weather & Corrosion Resistance
- 500h ASTM B117 NSS test (+6.2% resistance)
- 300h UVB313 aging test
- 100 cycles -40℃~85℃ temperature cycling (±4.1% resistance fluctuation)
3. Precise Casting & Assembly Matching
CT4-CT6 casing tolerance guarantees seamless assembly with standard drop-out fuse cutout housings, no loose contact.
4. Stable Mechanical Strength
≥370MPa tensile strength, can withstand frequent manual switching operation without deformation or cracking.
5. Full Drawing Customization Support
Free customization of size, shape, structure, wall thickness and material, full tailor-made production support.
6. Consistent Batch Quality
- ±0.3wt% copper composition
- ≤15MPa tensile fluctuation
- Dimensional consistency (batch deviation ≤±0.1mm)
- 99.5% first-pass yield to deliver fully consistent batch quality

FAQ
Q: Can you customize material grades of Cast Brass Drop-Out Fuse Parts for coastal salt fog environment?
A: Yes. For coastal high salt fog working conditions, we can customize tin bronze, silicon brass or anti-corrosion alloy brass to strengthen anti-rust and anti-oxidation performance.
Q: Do your cast brass fuse parts meet IEC 60282-2 high voltage fuse standard?
A: Yes. We provide material report, mechanical and dimension report, together with samples for customers test, trail assembly and verification.
Q: How long does it take to open a new custom mold for non-standard drop-out fuse cast parts?
A: Mold development 20–25 working days, samples 10-15 days.
Q: Can you engrave our brand logo, model number or serial codes on cast brass parts?
A: Yes, no extra processing fee for bulk orders.
Q: What is your monthly production capacity for full sets of cast brass drop-out fuse parts?
A: Monthly output of up to 100,000 sets of complete drop-out fuse brass components.
Q: Copper prices surge sharply recently, will your quotation for cast brass fuse parts change frequently?
A: Yes. We just maintain a certain profits, can not cover such high raw material price surge. To ensure customers always get reasonable prices for each orders, we have to keep a short valid quotation period.
Q: How do you stabilize costs for long-term bulk clients?
A: We pre-purchase raw materials based on long-term fixed supply contract, to lock price
Q: How do you control batch consistency to avoid size/conductivity differences in repeated orders?
A: We lock fixed brass material formulas, casting parameters, machining standards and plating processes for each customer's customized parts. All production parameters are archived permanently to eliminate batch-to-batch differences.
Q: Can your cast brass fuse parts fit overhead power distribution, mining power grids and wind farm power equipment?
A: Yes. Widely applicable in overhead urban/rural power grids, mining power systems, wind farm power protection and railway electrical distribution equipment.
