Surge arrester, 2P Type 2 (class C) type V20-2+FS-550 5095312

Protection of electrical installations against overvoltage – reliability and safety

This two-pole type 2 surge protector, class C, is a key element ensuring effective protection of electrical installations in residential and commercial buildings. It is designed to equalize potentials and protect against the effects of overvoltages, in accordance with VDE 0100-443 (IEC 60364-4-44). Its task is to minimize the risk of damage to electrical and electronic devices, as well as to prevent fires caused by installation failures.

This surge protector is characterized by a high discharge current capacity – up to 40 kA (8/20) per pole – thanks to the use of high-performance varistors. The short-circuit strength at the level of 20 kA guarantees its stable operation even in the event of serious disturbances in the network. The protection level of 2.4 kV (L-N) and 20 kV (N-PE) provides comprehensive protection against various types of overvoltages.

Mounting is done on a standard DIN TH-35 mm mounting rail, which facilitates integration with the existing electrical infrastructure. The compact size – only 2 modules – allows for saving space in the switchgear cabinet. Optical indication of operation facilitates quick identification of a faulty surge protector, and an optional remote signaling contact (FS) enables monitoring of the device status and immediate response in the event of a failure.

Application and benefits for installers and users:

• Versatility: Compatible with various network systems: TN, IT, TN-S, TT, TN-C-S and TN-C.
• Safety: Provides effective protection against overvoltages, protecting electrical devices and the installation from damage.
• Module replacement: Replaceable inserts with a dynamic disconnecting device and optical damage indication allow for quick and easy replacement of damaged elements without the need to replace the entire surge protector.
• Durability: Mechanical protection of the inserts protects against the effects of vibration and provides voltage coding for proper device operation.
• Easy installation: Mounting on a standard DIN TH-35 mm rail simplifies installation and integration with existing infrastructure.
• Status indication: Optical indication of operation and an optional remote signaling contact facilitate monitoring of the device status and quick reaction in the event of a failure.
• Housing: Made of self-extinguishing plastic (UL 94 V-0), which increases safety of use.
• Maximum wire cross-section: Supports wires with a maximum cross-section of 35 mm², which ensures compatibility with most electrical installations.
• Compliance with standards: Meets safety requirements, ensuring compliance with applicable regulations.

This surge protector is an investment in the safety and reliability of the electrical installation, which translates into peace of mind for both installers and end users.
