Surge protector T2 40kA 4P IT-440V 412233

Electrical installation protection with surge limiters

This four-pole type T2 surge limiter with a surge current of 40 kA is a key element in protecting the electrical installation from the effects of overvoltages. Designed to operate in IT networks with a voltage of 440V, it effectively protects electrical and electronic devices from damage caused by voltage surges. This limiter is used in both domestic and industrial installations, where protection against overvoltages is particularly important.

Functionality and application

This limiter is designed for mounting on a DIN TH-35 mm mounting rail and occupies 4 modules. Optical indication of the operating status facilitates quick identification of potential overvoltage problems. The ability to connect a wire with a cross-section of up to 35 mm² (stranded) or 25 mm² (flexible) ensures compatibility with various types of cabling. It is compatible with TN, IT, TN-C and TN-C-S network systems, making it a universal solution for many installations. The protection level of 2.1 kV guarantees effective protection against high overvoltages.

Key features and benefits

• Versatility: The limiter works with various network systems (TN, IT, TN-C, TN-C-S), increasing its usefulness in various applications.
• High efficiency: Surge current of 20 kA (peak value) and protection level of 2.1 kV provide solid protection against overvoltages.
• Status indication: Optical indication of operation allows for quick diagnosis and response in the event of an overvoltage.
• Easy installation: Mounting on a standard DIN TH-35 mm rail facilitates installation and integration with existing electrical infrastructure.
• Remote signaling: The ability to connect to a remote signaling system enables monitoring of the limiter status and rapid response to potential threats.
• Safety: Provides protection against damage to electrical and electronic devices caused by overvoltages, minimizing the risk of failures and downtime.
• Durability: Made of high-quality materials guarantees reliable operation for a long time.
