Surge limiter cartridge type V50-0-385 5093510

Surge protection for electrical installations

The V50-0-385 surge limiter insert is a component designed to protect electrical devices from the effects of overvoltages, both resulting from lightning strikes and disturbances in the power grid. It is a key element in ensuring the safety and reliability of the installation, minimizing the risk of damage and downtime.

This limiter, with protection class Type 1+2, effectively protects against both direct and indirect lightning strikes. Its construction based on a dynamic disconnecting device and optical damage indication allows for quick identification of the need for replacement after a surge. Mounting is done on a standard DIN TH-35 mm mounting rail, which facilitates integration with existing switchboards.

Application and characteristic features:

• Versatility: Suitable for use in various network configurations – although not dedicated to a specific configuration (TT, TN, IT), its universality allows for use in most installations.
• High efficiency: Rated AC voltage is 350 V, and the highest continuous operating voltage is 385 V. Protection level of 1.7 kV provides effective protection of sensitive electronic devices.
• High surge current capacity: Surge current level of 12.5 kA (10/350 µs) guarantees protection even with strong overvoltages.
• Safety and signaling: Optical damage indication allows for quick identification of the need for replacement, minimizing installation downtime.
• Solid construction: The housing made of self-extinguishing plastic (UL 94 V-0) ensures fire safety. Mechanical locking of the inserts protects against the effects of vibration and provides voltage coding.
• Compatibility: The maximum cross-section of flexible and rigid wire is 35 mm², which allows connection of wires of different thicknesses.
• Compact size: Occupies only 1 module in the switchboard, saving space.

This limiter is particularly recommended for use in residential, commercial and industrial buildings, where surge protection is crucial to ensure the continuity of operation of devices and the safety of users. Its installation should be carried out by a qualified electrician in accordance with applicable standards and regulations.
