5A 250V Time Delay Fuse (0X20) Automotive Overload Protection
$1.73
Description
Safeguard Your Automotive Electronics with Precision
The 5A 250V Time Delay Fuse (0X20) is engineered to protect sensitive car electronics from sudden power surges while allowing harmless startup currents (e.g., AC compressor engagement) without tripping. Its 30-second delay mechanism distinguishes it from standard fuses—ideal for circuits prone to brief voltage spikes but needing instant protection during sustained overloads (15–30A).
Key Advantages:
✔️ Dual-stage Protection: Delays response by 0–3 seconds to tolerate temporary surges but reacts instantly (≤0.1s) to dangerous overloads
✔️ Military-grade durability: Rated -40°C~+105°C with shock/vibration resistance up to 50G
✔️ Certified reliability: Meets ISO/TS 16949 & SAE J1127 standards (outperforms basic UL248 certifications)
| Feature | This Fuse | Standard Fuse |
|---|---|---|
| Surge tolerance | ±25% | ±10% |
| Response time (overload) | ≤100ms | ≤50ms |
| Temperature range | -40°C~+125°C | -25°C~+85°C |
Ideal Applications:
– Electric vehicle battery management systems
– Aftermarket stereo/charging system installations
– Fleet vehicle maintenance kits
Comes pre-insulated with color-coded markings for easy identification in tight engine compartments—a critical upgrade over non-delayed fuses that risk false tripping or delayed protection ($7.99/pack; includes 10 units). Perfect for DIY mechanics needing fail-safe circuit protection without sacrificing performance on cold starts or heavy-load scenarios.”
