Type 2 Surge Protector Acti9 iPRD20 1P+N 20 kA 350V

The Acti9 iPRD20 transient surge arrester (reference A9L20500) from Schneider Electric is an effective solution for protecting electrical installations against transient overvoltages, especially in medium-risk distribution boards. This type 2 device is designed to protect single-phase 1P+N systems and is ideal for incoming distribution boards in residential, commercial, or industrial environments. Its ability to absorb surges of up to 20kA ensures effective protection of equipment connected to the electrical network.

Main Features:

• Protection against transient overvoltages: The Acti9 iPRD20 is designed to protect electrical installations from overvoltages caused by transient events, such as lightning strikes or switching operations in the power grid. These overvoltages can damage sensitive electronic equipment and electrical systems, making a device like this crucial for ensuring the integrity of installations.
• Quick cartridge replacement: This device features plug-in cartridges, allowing for quick and easy replacement if the cartridge is damaged by a surge event. This feature minimises downtime and reduces maintenance costs, as there is no need to replace the entire unit.
• Versatile design: The Acti9 iPRD20 allows for phase, neutral, and earth cable entry from both the top and bottom, facilitating its installation in various distribution board configurations. This flexibility makes it compatible with a wide range of electrical installations.

Advanced Protection:

• Voltage protection level: This surge arrester provides effective protection in both common mode and differential mode. In differential mode (between phase and neutral), the protection level is 1.1kV, while in common mode (between neutral and earth) it is 1.4kV. These values ensure the device maintains the safety of connected equipment even during voltage spikes.
• Compatibility with earthing systems: The iPRD20 is compatible with TT and TN-S earthing systems, making it a versatile option for different network configurations. Additionally, it has a maximum continuous operating voltage (Uc) of 260VAC between neutral and earth, and 350VAC between phase and earth.

Capacity and Performance:

• Surge discharge capacity: This device has a discharge capacity of up to 20 kA, making it ideal for applications in distribution boards with a medium risk of overvoltages. It is capable of effectively protecting equipment against harmful transients that may arise in the power grid.
• Breaking capacity: The Acti9 iPRD20 surge arrester is used in conjunction with an associated circuit breaker, which can have a breaking capacity of up to 50 kA. This ensures that, in the event of a significant overvoltage, the system can respond adequately without causing damage to the equipment.

Technical Specifications:

• Nominal operating voltage (Ue): 230 VAC with a margin of +/- 10%, suitable for most low-voltage electrical networks.
• Compact dimensions: With dimensions of 36mm wide x 85mm high x 69mm deep, this device is compact and can be easily installed in modular cabinets.
• Weight: 211g, facilitating its handling and installation.
• Protection class: The product has a classification of IP20 and IP40 when mounted in a modular cabinet, ensuring its protection against the ingress of dust and solid objects.
• Operating temperature: The device operates efficiently within a range of -25°C to 60°C, making it suitable for a variety of environments, both residential and commercial.

Standards and Certifications:

The Acti9 iPRD20 complies with EN 61643-11 and IEC 61643-11 standards, ensuring that this device adheres to international surge protection standards. Additionally, it holds quality certifications such as KEMA-KEUR, NF, and CE, ensuring its reliability and compliance with European regulations.

Advantages of the Acti9 iPRD20:

• Flexible installation: Thanks to its design allowing cable entry from the top or bottom, the device is easy to install in different electrical board configurations.
• Easy maintenance: The ability to easily replace the cartridges ensures quick and efficient maintenance, minimising downtime in installations.
• High protection capacity: With a capacity of 20kA, this surge arrester offers reliable protection for medium-risk electrical systems, ensuring that connected equipment is protected against transient overvoltages.
