## Summary description

The ELEKTROPLAST BY7-40/1-275 is a high-performance surge arrester designed for electrical installations. This 1-pole device combines Type 1 and Type 2 (B+C) protection to safeguard equipment against transient overvoltages caused by atmospheric discharges or switching operations. It is suitable for AC power systems, ensuring reliable protection and operational safety for residential and industrial electrical circuits.

## Long description

The ELEKTROPLAST BY7-40/1-275 is a professional-grade surge arrester engineered to provide robust protection for electrical installations. This single-pole device integrates Type 1 and Type 2 (B+C) protection classes, effectively mitigating the risks posed by transient overvoltages resulting from atmospheric discharges, such as lightning strikes, or internal switching operations within the power grid. By diverting excess energy safely to the ground, it preserves the integrity of sensitive electronic equipment and electrical infrastructure.
Advantages
This surge arrester offers a comprehensive safety solution by combining the high discharge capacity of a Type 1 device with the precise voltage limitation of a Type 2 device in a single compact unit. Its design ensures a rapid response time to voltage surges, significantly reducing the stress on connected appliances and distribution boards. The durable construction is built for long-term reliability in demanding electrical environments, providing consistent performance and peace of mind for both residential and industrial applications.
Suitable for
Residential electrical distribution boards
Industrial power supply systems
Protection of sensitive electronic devices against power surges
Main distribution panels in buildings
This device is not intended for use in DC power systems, as it is specifically designed for AC electrical circuits. It should not be installed in environments where the operating voltage consistently exceeds the specified maximum continuous operating voltage, as this may lead to premature failure or safety hazards.
Key specifications
Protection class: Type 1+2 (B+C)
Number of poles: 1P
Application: AC power systems
Function: Transient overvoltage protection
Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is typically mounted on a standard DIN rail within the distribution board. Ensure that the connection to the protective earth conductor is secure and has the shortest possible path to minimize impedance during a surge event.
What to consider before purchase
Verify that the system voltage matches the device specifications
Ensure there is sufficient space on the DIN rail in your distribution board
Confirm that the local electrical installation requires Type 1+2 protection
For optimal performance, ensure that the grounding system of the building is properly maintained and meets current safety standards, as the effectiveness of the surge arrester is directly dependent on the quality of the earth connection.
