Widely applied in energy\u2011storage power\u2011station cabinets, maintenance safety disconnect \/ disconnector devices, lithium\u2011ion battery\u2011pack protection and DC relay backup short\u2011circuit protection. aR\u2011class fast\u2011acting characteristic provides reliable fault\u2011current protection for power semiconductors and high\u2011voltage DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Square\u2011body flush\u2011end contact with 2\u2011M10 mounting holes; max hole depth 11.5mm, min thread length 9.5mm. Apply specified bolt torque to avoid poor contact and over\u2011heating risk.<\/li>\n
- Recommended continuous operating current \u226475% of fuse rated\u2011current. Apply temperature\u2011derating\u2011factor Kt for ambient temperature above +40\u2103.<\/li>\n
- Altitude \u22642000m no\u2011derating; closed\u2011box installation between 2000\u20114500m: derate 2%\u20115% rated\u2011current per 1000m elevation increase. Re\u2011check insulation clearance according to GB\/T16935.1 for high\u2011altitude deployment.<\/li>\n
- Supports vertical, horizontal and inclined mounting; minimize negative gravity\u2011vibration impact on electrical contact performance.<\/li>\n
- Forced\u2011air cooling improves heat dissipation and increases allowable operating current, refer to Kv correction coefficient.<\/li>\n
- Do NOT replace fuse under live DC load unless equipped with certified load\u2011break switchgear, strictly follow 1000VDC high\u2011voltage safety operation procedure.<\/li>\n
- Replace fuse immediately if shell crack, deformation or mechanical damage appears.<\/li>\n
- Additional reliability validation test required for extremely high\u2011vibration industrial working conditions.<\/li>\n
- Select matched copper conductor cross\u2011section for terminals to control temperature\u2011rise performance.<\/li>\n
- Ordering reminder: part numbers with remark “Pending”, please confirm factory RoHS & REACH status before order placement.<\/li>\n<\/ul>\n
