설치 및 작동 참고 사항

• Square‑body mounting design; ensure good bolt contact to avoid poor contact and over‑heating risk.
• Recommended continuous operating current ≤75% of fuse rated‑current; apply temperature‑derating factor Kt when ambient temperature＞40℃.
• Altitude ≤2000m: no‑derating; for closed‑box installation within 2000‑4500m: derate 2%‑5% per 1000m elevation increase. Open‑air installation can normally ignore altitude influence; Insulation clearance needs re‑checking at high altitude, refer to GB/T16935.1.
• Supports vertical, horizontal and inclined mounting; for spring‑contact‑type fuses, prevent adverse gravity‑vibration influence on electrical contact.
• Forced air cooling can improve heat dissipation and increase allowable current, refer to Kv correction coefficient.
• 인증된 부하 차단 스위치 장치가 장착되어 있지 않은 경우, 활선 DC 부하 상태에서 퓨즈를 교체하지 마십시오.
• 퓨즈 본체에 기계적 손상, 균열 또는 변형이 발생한 경우 즉시 퓨즈를 교체하십시오.
• 극심한 진동이 발생하는 작업 환경에 대해서는 추가적인 신뢰성 검증 시험을 실시해야 합니다.
• 단자의 온도 상승 성능을 제어하기 위해 단자에 적합한 구리 도체 단면적을 선택하십시오.
