Surge arrester, 1P Type 1+2 (class B+C) type V50-1+FS-280 5093502

Surge protection in the installation – reliability and safety

This single-pole surge protector of class 1+2, designated as Type V50-1+FS-280, is a key element ensuring the protection of the electrical installation against the effects of lightning strikes and surges. It is designed for mounting on a TH-35 mm DIN rail and occupies only 1 module, making it easy to integrate with the existing distribution board. The device effectively protects against damage to electrical and electronic equipment, minimizing the risk of failures and downtime.

This surge protector is compatible with various network configurations – TT, TN, TN-C, TN-S and TN-C-S – making it a universal solution for a wide range of applications. The rated AC voltage is 230V, and the maximum continuous operating voltage is 280V. The surge current per pole reaches 12.5 kA (10/350 µs), guaranteeing effective protection even in the event of strong discharges. The protection level of 1.3 kV provides a high degree of protection against surges.

• Versatility: Designed for TT, TN, TN-C, TN-S and TN-C-S network configurations.
• High efficiency: Surge current of 12.5 kA (10/350 µs) provides protection against strong surges.
• Status indication: Has optical indication of operation and a signaling contact (NC/NO) informing about the need to replace the insert.
• Compact size: Occupies only 1 module on a TH-35 mm DIN rail – easy installation and saving space in the distribution board.
• Safety: Made of self-extinguishing plastic (UL 94 V-0).
• Mounting: Quick and easy mounting on a standard TH-35 mm DIN rail.

The surge protector is equipped with a signaling contact, which allows remote monitoring of the device status and a quick response in the event of a failure. In addition, the optical indication of damage allows visual control of the surge protector status without the need to disassemble it. The maximum conductor cross-section connected to the surge protector is 35 mm², which allows its use with various types of flexible and rigid conductors. The degree of protection IP20 provides protection against accidental contact.
