FAQ
Q1: Can NH0 fuse link be used in both AC690V industrial distribution and DC440V energy storage battery circuits?
A1: Yes, this NH0 fuse supports wide voltage coverage of AC400~690V and DC80~440V. Its high breaking capacity can handle both AC industrial short-circuit current and DC energy storage surge current, widely applicable for hybrid AC-DC new energy equipment.
Q2: What is the maximum continuous operating ambient temperature of NH0 high breaking capacity fuse?
A2: The normal operating temperature range is -25℃ ~ +70℃. If installed in fully sealed inverter cabinets with poor heat dissipation, we suggest reducing the actual operating current by 10% to avoid premature aging of the internal melt strip.
Q3: What is the difference between NT0 and NH0 fuse, can they replace each other?
A3: NT0 and NH0 adopt identical DIN installation dimensions and internal protection performance, which are completely interchangeable on the same fuse base. The naming difference only comes from different regional industry naming habits.
