Surge protective device iPRD20-T2-3 3-pole Type2 20 kA A9L20300

Electrical installation protection with surge arresters iPRD20-T2-3

This three-pole Type 2 surge arrester with a surge current of 20 kA is a key element in protecting the electrical installation from the effects of overvoltage. The device is designed for mounting on a TH-35 mm DIN rail and provides protection in 3-phase networks with a TN-C grounding system. Its compact design – occupying only 3 modules – makes installation easy even in crowded distribution boards.

The iPRD20-T2-3 arrester protects against overvoltages induced by lightning strikes nearby and against other disturbances in the network, such as switching on and off high-power devices. This minimizes the risk of damage to sensitive receivers, such as electronic equipment or building automation.

Key features and benefits:

• Effective protection: Rated discharge current of 20 kA guarantees high resistance to overvoltage, and the protection level of up to 1.4 kV (L-PE) and 1.1 kV (L-N) ensures the safety of the installation and connected devices.
• Versatility: Suitable for operation in TN-C networks, making it an ideal solution for most building and industrial installations.
• Status indicator: Optical indication of operation allows for quick identification of a faulty arrester and the need for its replacement – saving time and costs associated with diagnosing the problem.
• Easy installation: Mounting on a standard TH-35 mm DIN rail is quick and intuitive, which translates into time savings during installation.
• Safety: Short-circuit strength at the level of 50 kA provides additional safety in the event of a short circuit in the installation.
• Connection flexibility: The possibility of connecting wires with a cross-section of up to 25 mm² (solid/stranded) and 16 mm² (flexible) ensures compatibility with various types of cabling.

Application:

The iPRD20-T2-3 surge arrester is used in:

• Residential and commercial building installations,
• Main and sub-distribution boards,
• Distribution boards,
• Protection of sensitive receivers (computer equipment, automation, alarm systems),
• Industrial installations requiring a high level of protection against overvoltage.

This arrester is indispensable wherever protection against the effects of overvoltage is crucial for the reliable operation of devices and the safety of people. Its solid construction and high technical parameters guarantee long-lasting and effective protection of the electrical installation.
