Two terminal styles without blow indicator: BN\u2011flat bolted \/ UN\u2011DIN hook\u2011fork. Suitable for large\u2011capacity energy\u2011storage power\u2011station cabinets, lithium\u2011ion battery\u2011pack protection and DC relay backup short\u2011circuit protection. aR\u2011class fast\u2011acting performance delivers reliable fault\u2011current protection for power semiconductors and high\u2011power DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Size 3# square\u2011body construction; choose BN\u2011flat bolted or UN\u2011DIN hook\u2011fork terminal version according to cabinet layout. Apply proper bolt torque to prevent bad contact and over\u2011heating risk.<\/li>\n
- Recommended continuous working current \u226475% of fuse rated\u2011current. Apply temperature\u2011derating factor Kt when ambient temperature exceeds +40\u2103.<\/li>\n
- Altitude \u22642000m: no\u2011derating; closed\u2011box installation 2000\u20114500m: derate 2%\u20115% per 1000m elevation. Re\u2011check insulation clearance per GB\/T16935.1 for high\u2011altitude deployment.<\/li>\n
- Permits vertical, horizontal, inclined mounting. Avoid gravity\u2011vibration negative influence over electrical contact performance.<\/li>\n
- Forced\u2011air cooling improves heat dissipation and allowable operating current, refer to Kv correction coefficient.<\/li>\n
- Never replace fuse under live DC load unless equipped with certified load\u2011break switchgear.<\/li>\n
- Replace fuse immediately if shell crack, deformation or mechanical damage appears. This series has NO blow indicator for fuse burnout status.<\/li>\n
- Additional reliability validation test required for extremely high\u2011vibration industrial environments.<\/li>\n
- Select matched copper conductor cross\u2011section for terminals to control temperature\u2011rise performance.<\/li>\n
- Ordering reminder: specify terminal suffix BN or UN when placing order; models marked asterisk * need factory pre\u2011confirmation before order placement; Pending items require pre\u2011factory verification for RoHS & REACH status.<\/li>\n<\/ul>\n
