Installation & Operating Notes

• Size 2# square‑body; select B‑flat bolted horizontal or K‑hook‑fork vertical terminal version according to cabinet layout; apply specified bolt torque to avoid poor contact and over‑heating risk.
• Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating‑factor Kt for ambient temperature above 40℃.
• Altitude ≤2000m no‑derating; closed‑box installation between 2000‑4500m: derate 2%‑5% rated‑current per 1000m elevation increase. Open‑air installation normally ignores altitude impact. Re‑check insulation clearance at high altitude in compliance with GB/T16935.1.
• Supports vertical, horizontal and inclined mounting; prevent gravity‑vibration negative influence over electrical contact performance for spring‑contact‑type devices.
• Forced‑air cooling improves heat dissipation and increases allowable operating current, refer to Kv correction coefficient.
• Do NOT 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 EV and industrial environments.
• Select matched copper conductor cross‑section for terminals to control temperature‑rise performance.
• Ordering note: clarify terminal type B(flat bolted) or K(hook‑fork customized) when placing purchase order; electrical performance is identical for two terminal versions.
