Product Features of the Cylinder Fuse

Engineered specifically for demanding solar environments, this Cylinder Fuse guarantees uncompromised electrical isolation across heavy-duty DC switchgear.

  • High Voltage Capacity: Operates safely at 1500V DC across an 8A to 35A current range, ensuring reliable performance in modern PV plants.
  • Robust Fault Withstand: Resists massive grid anomalies utilizing a 50kA rated breaking capacity and a fast-acting gPV utilization category.
  • Thermal Efficiency: Features a high-grade quartz sand filling material, effectively minimizing arc energy and maintaining a low rated power dissipation (≤9.3W at 1In).
  • Standardized Form Factor: Housed in a compact 10x85mm fuse cylinder to optimize panel space within commercial combiner boxes and inverter inputs.

Industrial Applications for the Cylinder Fuse

Deploying the EKFL15D10L minimizes catastrophic electrical hazards across high-voltage infrastructures relying on a dependable Cylinder Fuse.

Applications & Use Cases

  • Solar Photovoltaic Arrays: Secures independent utility-scale strings and arrays against destructive direct current short circuits.
  • DC Combiner Boxes: Functions as a primary protective node before aggregated power reaches the central PV inverter.
  • Charge Controllers: Shields high-voltage energy storage routing systems and solar charge controllers from massive overload transients.
