Product Advantage
High-temperature sintered ceramic shell with strong environmental adaptability The ceramic shell is formed via one-piece firing at 1300℃, featuring impact resistance, wide temperature tolerance and excellent insulation performance. It will not crack, deform or leak electricity under long-term high temperature, damp and dusty working conditions of outdoor energy storage stations and factory electrical rooms.
Fully certified and manufactured per strict IEC and DIN safety standards, the Knife Blade Fuse Link NH00 features a precision-calibrated melt profile that ensures millisecond-level fault interruption. It provides comprehensive Short Circuit Protection NH00 against sudden inrush currents and electrical surges, effectively preventing equipment burnout, circuit breakdown and cabinet fire hazards. Built with high-temperature explosion-proof housing and anti-aging structural design, the AC 500V/690V NH00 Fuse Link minimizes operational risks in compact, high-load distribution environments, delivering long-term, high-safety circuit protection for industrial automation, photovoltaic systems and general power distribution applications.

FAQ
Q1: Can NT00 HRC Fuse Short Circuit Protection NH00 be applied to DC photovoltaic energy storage cabinets?
A1: Yes, this series supports AC500/690V and can also match DC250V energy storage circuits. The gG protection characteristic effectively resists instantaneous surge current during PV startup and avoids false fusing, providing reliable short-circuit protection for battery packs.
Q2: What is the MOQ if we need to print our own brand LOGO on the ceramic tube?
A2: The minimum order quantity for OEM LOGO printing is 50 pieces. We can also adjust the fuse internal melt structure to develop exclusive current specifications according to customers' circuit design requirements.
Q3: How long is the service life of this fuse under normal indoor working conditions?
A3: Under rated current and dry ventilated indoor environment, the service life can reach over 8 years. For outdoor high humidity and dusty scenarios, we recommend conducting visual inspection of the dual indicators every 12 months to check ceramic shell aging.
