Surge arrester DEHNflex M "DFL M 255" 924396

Surge protection in electrical installations

The DEHNflex M "DFL M 255" surge arrester is a reliable element protecting electrical installations from the effects of current surges and overvoltages. Designed for mounting in cable ducts, it provides effective protection for end devices with a voltage of 230V. It is a type 3 component, which means it works perfectly as a complement to the protection provided by higher classes of surge arresters.

Application and functionality

This device finds wide application in residential, commercial and industrial buildings, where surge protection is crucial to ensure continuity of operation and safety. Its compact dimensions allow for easy installation in installation boxes and cable ducts, making it an ideal solution for both new installations and modernization of existing ones. Acoustic signaling of the status informs about any operation of the arrester, enabling quick reaction and diagnosis of the problem.

Key features and benefits

• Effective protection: Provides a protection level of up to 1.5 kV (L-PE/N-PE) and 1.25 kV (L-N), minimizing the risk of damage to connected devices.
• High resistance: Withstands discharge current up to 3 kA (L+N-PE), effectively dissipating surge energy.
• Acoustic signaling: Enables quick identification of damage or operation of the arrester, which facilitates service and maintenance.
• Compact dimensions: Facilitate installation in tight spaces, such as installation boxes and cable ducts.
• Versatility: Suitable for use in various installation systems of 230 V end devices.
• Safety: Compliance with EN 61643-11 standard guarantees high quality and reliability.
• Overload protection: Maximum overcurrent protection up to 16 A protects against the effects of overloads in the circuit.

The DEHNflex M "DFL M 255" surge arrester is an investment in the safety and durability of the electrical installation, which allows you to avoid costly repairs and downtime caused by overvoltages. Its solid construction and precise workmanship guarantee long-term and trouble-free operation.
