Surge arrester 1000Vdc type V20-C 3PHFS-1000 5094574

Photovoltaic system protection – reliability and safety

This surge protector, designed for photovoltaic systems, provides comprehensive protection against the effects of lightning strikes and voltage surges in the grid. It is a key element ensuring the continuity of operation and safety of use. Type 2 device, designated as V20-C 3PHFS-1000, effectively minimizes the risk of damage to sensitive PV system components.

This surge protector is compatible with various network configurations – TN, IT, TN-S, TT, TN-C, TN-C-S and DC – making it a universal solution for a wide range of installations. Integrated short-circuit protection and the possibility of connecting fuses (up to 125A) increase the level of safety and allow for selective circuit protection. Optical indication of the device status facilitates quick identification of potential failures.

Key features and application

• Performance: Rated discharge current up to 20 kA (peak value 8/20) and maximum discharge current 40 kA guarantee effective protection even with strong surges.
• Low DC protection level: Protection level below 4 kV (Uoc max = 1000 V DC) is particularly important in photovoltaic installations, where voltages can be high.
• Versatility: Compatibility with various network configurations allows for use in almost any PV installation.
• Mounting: Mounting on a TH-35 mm DIN rail is simple and quick, which translates into time savings during installation.
• Status indication: Optical indication of damage allows for quick identification of the need for device replacement.
• Short-circuit protection: Integrated short-circuit protection increases safety and protects against potential failures.
• Application: Ideal for photovoltaic systems with or without an external lightning protection system.

The V20-C 3PHFS-1000 surge protector is a solid solution for professionals and end-users looking for reliable protection of their photovoltaic installations. Its construction based on varistors with a dynamic disconnecting device ensures long-term and efficient operation. Additionally, the error-tolerant Y-connection according to VDE 0100-712 (EN 50539-12) provides additional safety and reliability. The device occupies 4 modules in the switchgear, allowing for easy adaptation to the existing electrical infrastructure.
