Surge protector iPRD40r-T2-3N 3+1 pole Type2 40 kA with contact A9L40601

Protection of electrical installations with Acti9 surge arresters

The iPRD40r-T2-3N surge arrester is a key element ensuring the safety of electrical installations in residential and commercial buildings. The device effectively protects against the effects of lightning strikes and voltage surges in the network, minimizing the risk of equipment damage and preventing fires. Designed to work with TN-S and TT systems, it offers reliable protection in various network configurations.

Construction and application

This arrester, mounted on a TH-35 mm DIN rail, occupies 4 modules in the switchgear. Its 3+1 pole construction (3 phases + neutral) provides comprehensive protection for the entire circuit. The built-in remote signaling contact allows for quick detection of device operation and taking appropriate repair actions. Optical signaling on the housing further facilitates identification of the arrester's status. It is intended for protection against overvoltages in installations with a rated voltage of 400V and a maximum continuous operating AC voltage of 350V. The maximum discharge current it can withstand is as high as 40 kA, and the short-circuit withstand (Isccr) is 50 kA – guaranteeing its reliability even in extreme conditions.

Key features and benefits

• Versatility: Compatible with TN-S and TT network systems, making it a universal solution for various installations.
• High efficiency: Rated discharge current of 40 kA provides effective protection against strong surges.
• Fast diagnostics: Built-in remote signaling contact and optical indication of operation facilitate problem location and quick response.
• Safety: Protects electrical devices from damage caused by overvoltages, which translates to increased safety of use.
• Durability: Made of high-quality materials, guarantees long life and reliable operation.
• Installation flexibility: The ability to connect wires with a cross-section of up to 25 mm² (solid/stranded) and 16 mm² (flexible) ensures easy integration with the existing installation.
• Compliance with standards: Meets the required safety standards, confirming its high quality and reliability.

This arrester is an ideal solution for both professional installers looking for a reliable component for building safe electrical installations, and for end-users who care about protecting their equipment and the safety of their households.
