Citel DS50PV-500/51 SPD, type 2, PV, plug-in, 500VDC, 15kA
The Citel DS50PV-500/51 SPD is a Type 2 surge protective device (SPD) specifically designed for photovoltaic (PV) systems. It is a plug-in device used to protect PV installations against overvoltage events caused by lightning strikes or other electrical disturbances.
Here are the specifications of the Citel DS50PV-500/51 SPD:
- Type: Type 2 SPD
- Application: Photovoltaic (PV) systems
- Voltage Rating: 500VDC
- Nominal Discharge Current (In): 15kA
Type 2 SPDs are commonly installed at the main distribution board or the combiner box of PV systems to provide protection against transient overvoltages. The DS50PV-500/51 is specifically designed for DC applications, where the voltage level is 500VDC.
With a nominal discharge current of 15kA, this SPD can handle surge events and divert excessive current away from sensitive PV system components, such as inverters or charge controllers. It helps to prevent damage to the system and ensure its continued operation.
