Product information

Description

The Dehn DEHNvenCI 255 is a high-performance Type 1 single-pole surge arrester engineered to provide robust protection for low-voltage electrical installations. This device is specifically designed to mitigate the risks associated with lightning strikes and transient overvoltages, ensuring the safety and operational continuity of connected electrical equipment. By diverting high-energy surges safely to the ground, it acts as a critical barrier against electrical damage in both residential and industrial environments.

Advantages

This surge arrester offers exceptional reliability due to its high discharge capacity, which allows it to handle significant energy loads during atmospheric discharge events. Its compact single-pole design facilitates easy integration into existing distribution boards without requiring excessive space. The advanced internal technology ensures a low voltage protection level, providing a high degree of safety for sensitive electronic components downstream. Furthermore, its durable construction is built to withstand harsh environmental conditions, ensuring long-term performance and minimal maintenance requirements over its service life.

Suitable for

Industrial electrical distribution systems
Residential main power supply panels
Protection of sensitive electronic equipment
Low-voltage installations requiring Type 1 lightning protection

When it may not be suitable

This device is designed specifically for single-pole applications and may not be sufficient for complex multi-phase systems without additional coordinated protection devices. It is not intended for use in high-voltage transmission networks or circuits exceeding its rated voltage specifications.

Key specifications

Type: Type 1 surge arrester
Number of poles: 1
Discharge capacity: 25kA
Voltage protection level: 1.5kV
Application: Low-voltage electrical systems

How to use

The installation of the Dehn DEHNvenCI 255 should be performed by a qualified electrician in accordance with local electrical safety regulations. The device is typically mounted on a standard DIN rail within the main distribution board. It must be connected in parallel with the supply circuit, ensuring that the connection leads are kept as short as possible to maintain the effectiveness of the surge protection. Proper grounding is essential for the device to function correctly and safely dissipate surge energy.

What to consider before purchase

Verify the voltage requirements of your electrical system
Ensure compatibility with existing DIN rail mounting configurations
Confirm if a single-pole or multi-pole configuration is required for your specific setup
Check local electrical codes regarding lightning protection requirements

Usage recommendations

Regular inspection of the status indicator is recommended to ensure the device remains operational. If the indicator shows that the protection module has reached its end of life, the unit should be replaced immediately to maintain system safety.
