Surge protector, 3p Type 2 (class C) type V20-3+FS-385 5095303

Protection of electrical installations against overvoltage – reliability and safety

This three-pole type 2 surge protector, designated V20-3+FS-385, is a key element ensuring the protection of electrical installations in residential and commercial buildings. Designed to work with TN, IT and TT systems, it effectively protects against the effects of sudden voltage surges that can damage sensitive electronic devices. Its versatility makes it an ideal solution for both installers and end-users looking for comprehensive protection.

This surge protector is characterized by high performance – it withstands an impulse current of 40 kA (8/20 µs) and has the ability to dissipate peak energy of 20 kA. Integrated protection further increases the level of safety, and optical status indication allows for quick identification of any failure. Mounting is done on a standard DIN TH-35 mm rail, which simplifies and speeds up installation.

Functionality and parameters tailored to needs

The design of the surge protector has been carefully thought out in terms of maximum efficiency and durability. A protection level of 20 kV guarantees effective protection against atmospheric and switching surges. Thanks to the possibility of connecting wires with a cross-section of up to 352 mm², the surge protector is compatible with various types of installations. Additionally, the presence of a remote signaling contact enables integration with monitoring and notification systems, allowing for a quick response in the event of a failure.

The V20-3+FS-385 surge protector has been designed to provide the highest level of protection in various electrical network configurations. Its ability to operate in IT systems and its high L-N (1.7 kV) and N-PE (1.2 kV) protection levels make it an ideal choice for demanding industrial and commercial applications. The rated AC voltage of 385 V and the highest DC continuous operating voltage of 505 V ensure compatibility with most standard electrical installations.
