Surge limiter cartridge PRD1-N-INS 16317

Protection of electrical installations against overvoltage

The PRD1-N-INS surge limiter insert is a safety element protecting the electrical installation against the effects of overvoltages, both switching and induced. This is particularly important in places exposed to frequent voltage changes or direct lightning strikes. Mounting is done on a base, which ensures easy replacement and maintenance.

Construction and application

The PRD1-N-INS insert is designed to work with Acti 9 series surge limiters. Optical signaling of device operation informs about the need to replace the insert after a surge occurs. This allows for quick restoration of full installation protection. This limiter finds application in TN and TT installations, providing effective protection in various electrical network configurations.

Key features and benefits

• High protection efficiency: Rated discharge current at 20 kA (peak value 8/20) guarantees protection against strong overvoltages.
• Optical signaling: Built-in optical indicator informs about the need to replace the insert after activation, which facilitates service and maintenance of the protection system.
• Versatility: Possibility of use in TN and TT installations ensures a wide range of applications.
• Safety: Protection level of 1.5 kV minimizes the risk of damage to connected devices.
• Simple installation: Mounting on a base facilitates the replacement and maintenance of the surge limiter.
• Rated AC voltage: 230 V – adapted to standard electrical installations.
• Degree of protection IP20: Provides basic protection against accidental contact.

It is worth remembering that regular inspection of the condition of surge limiter inserts is crucial to ensure the continuity of protection of the electrical installation and the devices connected to it. Replacing a damaged insert avoids serious failures and costly repairs.
