Suitable for 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 DC\u2011side power components.<\/p>\n Installation & Operating Notes<\/h2>\n\n- Size 01* square\u2011body with 2\u2011M8 bolt mounting holes; select B\u2011with blow\u2011indicator or AN\u2011without blow\u2011indicator version according to cabinet layout. Apply specified bolt torque to avoid poor 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.<\/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 version B (blow indicator) or AN (no indicator) when placing purchase order; electrical performance is fully identical for two versions.<\/li>\n<\/ul>\n
