Surge protective device iPRD20-T2-3N 3+1 conductor Type2 20 kA A9L20600

Electrical installation protection with surge limiters Schneider Electric iPRD20-T2-3N

The iPRD20-T2-3N surge limiter is a key element in protecting electrical installations from the effects of lightning strikes and voltage surges in the network. The device is designed to protect circuits in residential, commercial and industrial buildings, ensuring the safety of electrical equipment and minimizing the risk of failure. Mounting on a TH-35 mm DIN rail makes integration with an existing distribution board simple and quick.

Construction and application

This limiter, manufactured by the renowned Schneider Electric, features a 3+1 pole design (L+N+PE), providing comprehensive protection for three-phase installations with a neutral conductor. Protection class Type 2 means that the device effectively suppresses both lightning strikes and fast transient overvoltages. Optical indication of the operating status facilitates identification of the need for replacement or control of the device after a surge.

The application of the iPRD20-T2-3N limiter is particularly important in places exposed to frequent lightning strikes or in areas with an unstable power grid. It protects sensitive electronic devices such as computers, televisions, RTV and household appliances, as well as building automation systems. The ability to connect wires with a cross-section of up to 35 mm² ensures compatibility with most standard electrical installations.

Key features and benefits

• High protection efficiency: Maximum discharge current of 20 kA and protection level of 1.1 kV (L-N) and 1.4 kV (N-PE) guarantee effective protection against overvoltages.
• Versatility: Compatible with TN-S and TT network systems – most commonly found in residential and commercial buildings.
• Simple installation: Mounting on a standard TH-35 mm DIN rail facilitates installation and replacement of the device.
• Status indicator: Optical indication of operation allows for quick identification of the need to replace the limiter after a surge.
• Durability: Short-circuit withstand (Isccr) at 50 kA level ensures resistance to damage during short circuits in the installation.
• Safety: No leakage current eliminates the risk of additional hazards associated with the operation of the device.
• Solid construction: Occupies 4 modules in the distribution board, allowing for efficient use of space.
