) or maximum (
) discharge current. These devices are often Type 1 or Type 2, operating at
or lower, commonly in 2P, 3P, or 4P configurations for residential or industrial panels.
Key Features and Applications:
- Capacity: 15kA rating (often for Type 1 orfor Type 2) indicates ability to handle significant transient surges.
- Application: Ideal for AC power systems to protect against lightning strikes (Type 1) or switching surges (Type 2) in, for example, Citel DACF15S or Jinli 3P 15kA products.
- Voltage Range: Typically designed for networks, with a Maximum Continuous Operating Voltage () usually around.
- Protection Type: Available in Type 1+2 for main boards, or Type 2/3 for sub-panels and sensitive equipment, often with pluggable modules for easy maintenance.
Common Specifications:
- Voltage Protection Level ():

What is the difference between AC SPD and DC SPD?
Key Differences Between AC and DC SPDs:
AC voltage alternates in cycles with positive and negative swings, whereas DC voltage is constant and unidirectional. AC SPDs are optimized for alternating waveforms, whereas DC SPDs are designed to handle continuous voltage levels, particularly in solar energy systems.Aug 2, 2025
