Note di installazione e selezione
- Scollegare l'alimentazione principale prima dell'installazione o della sostituzione per evitare il rischio di cortocircuiti accidentali.
- Strictly apply mounting torque 20.0 Nm ±1 Nm; insufficient torque will trigger severe over‑heating under ultra‑high‑current working‑condition.
- Select fuse rated‑current to be 1.1‑1.25 times of circuit continuous‑working‑current; never upgrade to higher‑ampere rating arbitrarily.
- Ambient temperature affects actual carrying‑capacity, temperature derating calculation shall be performed for engine‑compartment or closed‑cavity installation.
- Replace only with identical specification fuses to guarantee original circuit‑protection‑performance.
FAQ

Q: What is the rated‑voltage of this heavy‑duty fork bolt‑down fuse?
A: Rated voltage range reaches 125‑250V DC, suitable for high‑voltage new‑energy DC‑power‑net scenarios.
Q: What amp ratings are available for this heavy‑duty bolt‑down fuse?
A: Available amp ratings cover 60A,70A,80A,100A,125A,150A,175A,200A,225A,250A,275A,300A,350A,400A,450A,500A,550A,600A,650A,700A.
Q: What mounting torque and hole‑spacing should I adopt?
A: Dual M8 mounting‑holes with 56 mm centre‑to‑centre‑distance; required tightening torque:20.0 Nm ±1 Nm. Improper torque will lead to contact over‑heating risk under heavy‑load.
Q: Which standard does this high‑voltage heavy‑duty bolt‑down fuse comply with?
A: Complies with ISO 20934‑2019 international special‑purpose vehicle fuse standard.
Q: Does high‑voltage heavy‑duty bolt‑down fuse need temperature derating?
A: Yes. Actual continuous‑current‑carrying‑capacity drops when ambient‑temperature rises. Derating evaluation is essential for confined high‑temperature installation space.
Q: Can you provide bulk‑order and OEM custom‑marking service?
A: Yes, bulk wholesale, laser marking and custom‑packaging services are supported. Please send amp ratings and quantity requirement for datasheet and formal quotation.
