Surge arrester, 1P Type 1+2 (class B+C) type V50-1-280 5093500

Electrical installation protection – surge arrester V50-1-280

This single-pole surge arrester of class 1+2 (B+C) is a key element in protecting the electrical installation from the effects of atmospheric and switching surges. The device is designed to work with 230V installations, providing protection at a level of 1.3kV. Its compact size – only 1 module – makes it easy to mount on a TH-35 mm DIN rail, saving valuable space in the distribution board.

The V50-1-280 arrester is not only protection but also convenience. Designed with easy diagnostics in mind, it has optical damage indication, informing about the need to replace the insert. It is compatible with various network types – TN-S, TN-C-S, TT and TN – making it a universal solution for a wide range of applications. The maximum wire cross-section of 35 mm² allows connection of both solid and stranded, and flexible wires.

Key features and benefits:

• Versatility: Designed for TN-S, TN-C-S, TT and TN networks, eliminating the need to have many different models for different types of installations.
• High efficiency: Protection class Type 1+2 provides effective protection against both atmospheric (lightning strikes nearby) and switching surges (e.g. switching on large loads).
• Easy diagnostics: Optical damage indication facilitates quick identification of the need to replace the insert, minimizing installation downtime.
• Compact dimensions: Occupies only 1 module on the DIN rail, which is especially important in tight distribution boards.
• Universal wire cross-section: Support for wires up to 35 mm² ensures compatibility with most standard installations.
• Safety: Compliance with EN 61643 standards confirms the high quality and safety of the device.

Application and installation:

The V50-1-280 arrester is used in residential and commercial buildings, protecting electrical devices from damage caused by surges. Installation is done by snapping onto a standard TH-35 mm DIN rail. Remember to select the correct wire cross-section and observe appropriate safety precautions when working with live equipment. The device is ideal for use in lightning protection systems of level III and IV according to VDE 0185-305 (IEC 62305).
