Surge arrester, 3p Type 2 (class C) type V20-3+FS-550 5095313

Electrical installation protection – reliable surge arrester

This three-pole type 2 surge arrester, class C, is a key element ensuring the safety of electrical installations in residential and commercial buildings. It provides effective protection against the effects of surges that can damage sensitive electronic devices. Its design and parameters have been selected to meet the requirements of modern electrical installations.

This arrester is designed for mounting on a DIN TH-35 mm mounting rail, which facilitates its installation and integration with the existing distribution board. Optical indication of the device status allows for quick identification of any failures or the need to replace the insert. Additionally, the presence of a remote failure signaling contact (FS) allows it to be connected to a monitoring system, which increases the level of safety and allows for proactive response to potential problems.

Application and benefits for professionals:

• Versatility: Compatible with TN, TN-S and TN-C-S, as well as TN-C networks. This allows it to be used in a wide range of installations.
• High efficiency: The ability to discharge a surge current of up to 40 kA (8/20) per pole guarantees effective protection against strong surges. Short-circuit strength at 20 kA ensures stable operation in the event of a short circuit.
• Safety and reliability: Mechanical protection of inserts and voltage coding minimize the risk of incorrect installation and ensure long-term reliability. The housing made of self-extinguishing plastic (UL 94 V-0) increases fire safety.
• Easy diagnostics: Optical indication of the device status and a remote failure signaling contact facilitate quick identification of problems and minimize downtime.
• Compact size: Occupies only 3 modules on the DIN rail, saving space in the distribution board.

For the end user this means:

• Equipment protection: Effective protection of connected electronic devices against damage caused by surges, which translates into financial savings and avoiding unpleasant failures.
• Safety: Increased safety of using the electrical installation and protection against potential hazards related to surges.
• Peace of mind: Confidence that the electrical installation is properly protected and operates reliably for a long time.

The arrester is characterized by a protection level of 2.4 kV (L-N) and 20 kV (N-PE), which provides comprehensive protection against various types of surges. The maximum discharge current (8/20) is 40 kA, and the rated discharge current - peak value (8/20) is 15 kA – these values guarantee effective protection even in the event of strong disturbances in the power grid. The highest permanent operating AC voltage is 550 V and DC 745V, making it a universal solution for many applications.
