Type 1+2 transient surge protector Acti9 iPRD1 3P+N 12;5r 350V

The Acti9 iPRD1 12.5r surge arrester, reference A9L16482 by Schneider Electric, is an advanced protection device designed to safeguard electrical installations from direct and indirect transient overvoltages in residential buildings and small commercial systems. This Type 1+2 device combines protection for high-energy events, such as direct lightning strikes, with additional protection against more common overvoltages caused by network switching operations. It is a comprehensive solution for the protection of electrical installations requiring a high level of safety on the incoming panel board.

Applications:

The Acti9 iPRD1 12.5r is designed to protect electrical installations in residential and small commercial environments. It is ideal for use in areas with a high risk of overvoltage exposure, such as lightning-prone zones, where overvoltages can severely affect electrical equipment. This surge arrester is recommended for TT and TN-S systems, offering protection in both differential mode (between phase and neutral) and common mode (between neutral and earth).

Main Features:

• Type 1+2 Protection: The device combines the features of a Type 1 protector (protection against direct overvoltages such as atmospheric discharges) and Type 2 (protection against overvoltages induced by switching operations in the electrical network), ensuring comprehensive protection under all conditions.
• Replaceable Plug-in Cartridges: The Acti9 iPRD1 12.5r includes plug-in and replaceable protection cartridges, facilitating its maintenance. If the cartridge is damaged by an overvoltage, the system indicates it needs to be replaced, ensuring continuous protection without the need to replace the entire device.
• Safe End-of-Life Disconnector: This surge arrester incorporates a end-of-life disconnector, ensuring the device shuts down safely if the cartridge reaches the end of its life, preventing potential electrical risks in the installation.

Technical Specifications:

• Maximum Discharge Current (Imax): The device is designed to handle a maximum discharge current of 50 kA, enabling it to effectively protect against severe overvoltages caused by atmospheric discharges or similar events.
• Nominal Discharge Current (In): The nominal discharge current is 20 kA, ensuring reliable protection against more common overvoltages in electrical networks.
• Cut-off Capacity of 70 kA: This surge arrester has a cut-off capacity of 70 kA, ensuring it can disconnect the system in the event of extreme overvoltage events, protecting connected equipment and the electrical system in general.
• Continuous Operating Voltage (Uc): The device can operate with a maximum continuous voltage in differential mode of 350 V AC (between phase and neutral) and 255 V AC in common mode (between neutral and earth), ensuring its compatibility with 230 V or 400 V AC networks.

Additional Advantages:

• Remote Indicator: The Acti9 iPRD1 12.5r features a remote reporting function, indicating when the protection cartridge needs replacement. This feature is especially useful for maintaining installation protection without constant physical inspection.
• DIN Rail Mounting: The device is designed for mounting on DIN rails, facilitating its integration into modular electrical panels. Additionally, its compact design (72 mm wide, 89 mm high, and 69 mm deep) ensures easy installation in distribution boards, even in confined spaces.
• High Durability: This surge arrester is designed to operate over a wide temperature range, from -25°C to 60°C, and can be stored under extreme conditions with temperatures from -40°C to 80°C, guaranteeing its reliability in various environmental conditions.

Additional Specifications:

• IP20/IP40 Protection Rating: Under normal conditions, the Acti9 iPRD1 12.5r has a protection rating of IP20, protecting it against the ingress of solid objects larger than 12.5 mm, and can reach IP40 when installed in a modular cabinet, providing greater protection against dust and other particles.
• Certifications: This surge arrester complies with EN 61643-11:2012 and IEC 61643-11:2011 standards, ensuring it meets the highest safety and quality standards in surge protection.

Benefits of the Acti9 iPRD1 12.5r:

• Comprehensive Protection: The combination of Type 1+2 protection ensures that electrical equipment and systems are protected against both direct and indirect discharges, making it a reliable solution for high overvoltage risk areas.
• Easy Maintenance: The replaceable cartridges allow for quick and easy maintenance, ensuring continuous protection without the need to replace the entire device.
• Safety and Reliability: The integrated end-of-life disconnector ensures the device shuts down safely when the cartridges are damaged, protecting users and preventing electrical risks in the installation.
