Bettermann 5093500 Surge Protection Device B+C 1P 12.5kA 280V

The Bettermann 5093500 is a high-performance combined B+C class surge protection device engineered for single-phase electrical systems. It serves as a critical component in safeguarding electrical infrastructure by limiting transient overvoltages caused by atmospheric discharges or switching operations. With a robust design, this device ensures the integrity of sensitive electronic equipment in both residential and commercial environments.

Advantages

This surge protection device offers a reliable defense mechanism by combining the capabilities of class B and C arresters into a single unit, which simplifies installation and saves space in the distribution board. Its high discharge capacity of 12.5kA allows it to effectively handle significant energy surges, while the maximum continuous operating voltage of 280V ensures stability during standard grid fluctuations. The device is built for durability and consistent performance, providing peace of mind by preventing costly damage to connected appliances and control systems.

Suitable for

• Residential electrical distribution boards
• Commercial office building power systems
• Protection of sensitive electronic devices and appliances
• Single-phase electrical installations

This device may not be suitable for three-phase electrical systems, as it is specifically designed for single-phase configurations. It is also not intended for use in environments where the expected surge energy exceeds the specified 12.5kA discharge capacity or where the operating voltage consistently exceeds 280V.

Key specifications

• Protection class: B+C
• System type: Single-phase
• Discharge capacity: 12.5kA
• Maximum continuous operating voltage: 280V

How to use

The device should be installed by a qualified electrician within the main distribution board or a sub-distribution panel. It is typically mounted on a standard DIN rail. Ensure that the connection cables are kept as short as possible to maintain optimal protection levels. The device must be wired in parallel with the electrical circuit it is intended to protect, ensuring that the grounding connection is secure and compliant with local electrical safety standards.

What to consider before purchase

• Verify that your electrical system is single-phase
• Check the available space in your distribution board
• Ensure the device meets the specific surge protection requirements of your local grid
• Confirm that the installation will be performed by a certified professional

Usage recommendations: Regularly inspect the status indicator on the device to ensure it remains operational. If the indicator shows that the protection module has reached the end of its service life, replace the unit immediately to maintain continuous safety.
