Surge limiter insert type V20-C 0-440 5099706

Surge protection for electrical installations

The V20-C 0-440 surge limiter insert is a component designed to protect electrical devices from the effects of sudden voltage increases. It is an element used in both home and industrial installations, where power supply stability is crucial for the proper functioning of equipment. Its task is to divert excess energy to ground, minimizing the risk of damage and ensuring continuity of operation.

Construction and application

The V20-C 0-440 insert is a replaceable element in OBO BETTERMANN surge limiters. Designed for mounting in circuits with a rated voltage of 440V AC, it provides effective protection against atmospheric surges (lightning strikes) and surges resulting from switching loads. Thanks to its construction, this insert is characterized by a fast response to voltage increases and a high ability to suppress impulses. This is particularly important for sensitive electronic devices, such as computers, televisions or control systems.

Advantages and benefits

• Effective protection: Protects devices from damage caused by surges, extending their lifespan and minimizing repair costs.
• Fast response: C characteristic ensures a quick response to sudden voltage increases, which is crucial for protecting sensitive devices.
• Easy replacement: The insert is easily replaceable, which facilitates servicing and maintenance of the lightning protection system. If the limiter operates, replacing the insert restores the full functionality of the protection system.
• Versatility: Can be used in various types of electrical installations – both in residential and industrial buildings.
• Compliance with standards: The product meets applicable safety standards, guaranteeing reliable operation and safety of use.
• Protection against interference: Helps reduce electromagnetic interference, which can negatively affect the operation of electronic devices.
