It is widely used for energy\u2011storage power\u2011station cabinets, maintenance safety disconnect switches, lithium\u2011ion battery\u2011pack and DC relay backup short\u2011circuit protection. aR\u2011class fast\u2011acting characteristic provides reliable fault\u2011current protection for power semiconductors and DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Size 2# square\u2011body; select BN\u2011flat bolted or UN\u2011DIN hook\u2011fork terminal according to cabinet layout. Apply specified bolt torque value to avoid poor contact and over\u2011heating risk. This series has NO built\u2011in blow indicator for fuse burnout status.<\/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 occurs.<\/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: specify suffix BN (flat bolted) or UN (DIN hook\u2011fork) on purchase order; Pending\u2011marked items need factory pre\u2011verification for RoHS & REACH status.<\/li>\n<\/ul>\n
