Surge arrester 230V type VF2-230-AC/DC-FS 5097939

Electrical installation protection with status indication

The VF2-230-AC/DC-FS surge arrester is a reliable element for protecting electrical installations from the effects of overvoltages, both those caused by atmospheric discharges and disturbances in the network. Designed as a type 3 surge limiter, it effectively protects connected devices from damage. Its versatility makes it suitable for many installations, both in residential and commercial buildings.

Functionality and installation

Installation is carried out on a standard DIN TH-35 mm mounting rail, which simplifies and speeds up installation. The arrester has three poles and is adapted for conductors with a maximum cross-section of 2.5 mm². Equipped with a potential-free changeover contact for remote status indication, it enables quick identification of any activation and the need for replacement. This is particularly important for service technicians servicing extensive systems, where manual inspection of each device would be time-consuming.

Key features and benefits

• Type 3 protection: Provides effective protection against residual overvoltages after the operation of other protective devices (e.g. type 1 and 2 limiters).
• Rated current 20A: This makes the arrester suitable for most standard circuits in buildings.
• Remote indication: Allows monitoring of the device status without the need for visual inspection – saving time and service costs.
• Compact dimensions (17.5 mm): Allow mounting in tight switchboards without space problems.
• Y connection: Provides optimal protection for all phase, neutral and PE protective conductors.
• High L-N protection level (1000 kV): Guarantees effective suppression of interphase disturbances.
• Total discharge current 7 kA: The arrester will withstand strong current pulses associated with lightning strikes.
• Screwless connection terminals: Facilitate and speed up the connection of conductors, eliminating the risk of loosening connections.

The VF2-230-AC/DC-FS surge arrester is a solid solution for anyone who cares about the safety of their electrical installation and sensitive electronic equipment. Its design and technical parameters meet the requirements of EN 61643-11, ensuring reliable operation and long-term protection.
