Surge limiter cartridge type V20-C 0-500PV 5099708

Surge protection for photovoltaic installations and beyond

This V20-C 0-500PV surge limiter insert is a key element ensuring the safety of electrical installations, especially photovoltaic systems. It is designed to protect against the effects of sudden voltage surges that can damage sensitive equipment. Its versatility makes it suitable for both home and industrial installations.

Construction and application

The insert is intended for mounting in OBO BETTERMANN surge limiters, offering reliable protection against atmospheric surges and network disturbances. It is a type 2 component, which means it provides indirect surge protection, ideally complementing type 1 limiters (direct protection). Its compact size – only 1 module – allows for easy integration with existing switchboards. It is designed to operate in TN, TT, TN-S, TN-C and TN-C-S and DC networks.

Key features and benefits

• High protection efficiency: Rated discharge current up to 20 kA (peak value 8/20) and maximum discharge current 40 kA guarantee effective protection against even strong surges.
• Wide voltage range: Supports both AC voltages (up to 440 V) and DC voltages (up to 500 V), making it an ideal solution for photovoltaic systems.
• Optical status indication: Built-in optical indicator informs about the operation of the limiter, facilitating quick identification of a damaged element and the need for replacement.
• Safety and durability: Protection level of 2 kV minimizes the risk of damage to devices connected to the installation.
• Universal mounting: Base mounting ensures easy installation and replacement in standard switchboards.
• Large wire cross-section: Supporting wires with a maximum cross-section of 35 mm² allows connection of most typical installations.
• Application in photovoltaic systems: Specifically designed to work with PV installations, providing optimal protection against surges generated by solar panels and atmospheric phenomena.

This limiter complies with safety standards, confirming its high quality and reliability. Thanks to this, you can be sure that your electrical installation is properly protected against the effects of unforeseen events.
