Varistor module T2 40kA 600 VDC 414185

Surge Protection in Photovoltaic Installations and Beyond

The varistor module is a key component for protecting electrical installations, especially those exposed to dynamic voltage fluctuations, such as photovoltaic systems. This model, with a rated voltage of 600 VDC and the ability to discharge impulses with energy up to 40 kA, provides effective protection against the effects of atmospheric discharges and other surges. Its compact size – just one module – facilitates installation in distribution boards.

Construction and Application

Built on varistor technology, the design enables rapid response to sudden voltage spikes, diverting them to ground and protecting connected devices. This module is used in DC installations where surge protection is critical for ensuring reliable operation and long component lifespan. It is an ideal solution for both photovoltaic system installers and end-users seeking comprehensive protection for their installations. The possibility of use in various network configurations (including non-standard TN, TT, or IT systems) increases its versatility.

Key Features and Benefits

• High Protection Efficiency: Rated discharge current of 20 kA (peak value) and maximum discharge current of 40 kA guarantee protection against even strong surges.
• Versatility: Designed for operation in DC systems at 600 VDC, with applicability in various network configurations.
• Compact Dimensions: Occupies only one module in the distribution board, facilitating installation even in tight spaces.
• Simple Installation: Mounting is performed on a base, simplifying the installation and replacement process.
• Safety: Protection level of 2.5 kV ensures effective insulation and minimizes the risk of damage.
• Durability: Maximum continuous DC operating voltage of 720 V ensures long-term and reliable device operation.
• No Trigger Indication: The absence of visual trigger indication means there is no need for continuous monitoring of the module status – its role is discreet protection.
• IP20 Protection Rating: Provides basic protection against contact and contamination inside the distribution board.

This varistor module is an investment in the safety and reliability of your electrical installation – for both professionals and end-users who value peace of mind.
