Installations- und Betriebshinweise
- Size 2# square‑body; select B‑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; for spring‑contact‑type devices, prevent gravity‑vibration negative influence over electrical contact performance.
- 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.
- Die Sicherung muss sofort ausgetauscht werden, wenn Risse im Gehäuse, Verformungen oder mechanische Beschädigungen auftreten.
- Für industrielle Umgebungen mit extrem hohen Vibrationen ist ein zusätzlicher Zuverlässigkeitsvalidierungstest erforderlich.
- Select matched copper conductor cross‑section for terminals to control temperature‑rise.
- Ordering note: clarify terminal type B(bolted) or K(hook‑fork customized) when placing purchase order, electrical performance is identical for two versions.
