Surge protector T2 40kA 3P 412242

Electrical installation protection with surge limiters

This three-phase Class T2 surge limiter with a 40 kA impulse current is a key element in protecting electrical installations from the effects of atmospheric and switching surges. It provides protection for electrical and electronic devices in residential, commercial and industrial buildings. Its mounting on a TH-35 mm DIN rail is simple and quick, which will be appreciated by installers.

Functionality and application

This limiter effectively reduces the voltage to a safe level in the event of a surge, protecting connected devices from damage. It is designed for use in TN-C, TN-C-S and TT networks, making it a universal solution for different types of installations. The optical indication of the device status informs about its operation, facilitating diagnostics and maintenance. The ability to connect to a remote signaling system allows monitoring of the limiter status from a central point.

Key features and benefits

• High protection efficiency: Impulse current of 40 kA guarantees effective protection against strong surges.
• Versatility: Compatible with various network systems (TN-C, TN-C-S, TT).
• Simple installation: Mounting on a standard TH-35 mm DIN rail facilitates and speeds up installation.
• Status indicator: Optical indication of operation facilitates identification of a faulty limiter.
• Remote signaling: The possibility of connecting to a remote monitoring system ensures full control over the surge protection status.
• Rated capacity: Suitable for conductors with a cross-section of up to 35 mm², allowing its use in installations with higher loads.
• Reliability: Made of high-quality materials, ensuring long-lasting and trouble-free operation.
• Compact dimensions: Occupies only 3 modules on the DIN rail, saving space in the switchgear cabinet.

This limiter is an ideal solution for both new installations and modernization of existing surge protection systems. It ensures the safety and reliability of electrical devices, minimizing the risk of costly failures and downtime.
