Installation & Operating Notes
- Size 01* square‑body with 2‑M8 bolt mounting holes; select B‑with blow‑indicator or AN‑without blow‑indicator version according to cabinet layout. Apply specified bolt torque to avoid poor contact and over‑heating risk.
- Recommended continuous working current ≤75% of fuse rated‑current. Apply temperature‑derating factor Kt when ambient temperature exceeds +40℃.
- Altitude ≤2000m: no‑derating; closed‑box installation 2000‑4500m: derate 2%‑5% per 1000m elevation. Re‑check insulation clearance per GB/T16935.1 for high‑altitude deployment.
- Permits vertical, horizontal, inclined mounting. Avoid gravity‑vibration negative influence over electrical contact performance.
- Forced‑air cooling improves heat dissipation and allowable operating current, refer to Kv correction coefficient.
- Never replace fuse under live DC load unless equipped with certified load‑break switchgear.
- Replace fuse immediately if shell crack, deformation or mechanical damage appears.
- Additional reliability validation test required for extremely high‑vibration industrial environments.
- Select matched copper conductor cross‑section for terminals to control temperature‑rise performance.
- Ordering reminder: specify version B (blow indicator) or AN (no indicator) when placing purchase order; electrical performance is fully identical for two versions.
