Spark arrester insert type C50-0-255 5095609

Surge protection in the installation – reliability and safety

Spark gap insert C50-0-255 is an element protecting the electrical installation against the effects of overvoltages, both resulting from lightning strikes and induced by fast switching of loads. Its task is to dissipate excess energy to the ground, protecting connected devices from damage. This is particularly important in residential, commercial and industrial buildings, where failures caused by overvoltages can generate significant financial losses and pose a threat to safety.

This model, designated as Type 1+2 (class B+C), combines the features of a Type 1 and Type 2 surge arrester, providing comprehensive protection. This means that it effectively reacts to both direct lightning strikes (by dissipating a large surge current of up to 50kA) and overvoltages originating from the power grid. The installation of this type of insert is often required by standards and regulations regarding lightning protection.

Key features and application:

• Versatility: The insert works with various network systems – TN-S, TN-C-S and TT – making it a universal solution for most installations.
• High efficiency: Provides a protection level of up to 1.5kV, minimizing the risk of damage to sensitive electronic devices.
• Status indication: Optical indication of operation allows for quick identification of a damaged insert and the need for its replacement. This facilitates maintenance and ensures continuity of protection.
• Mounting: Designed for mounting on a TH-35 mm DIN rail, which facilitates integration with existing electrical distribution boards. The compact size (1 module) allows for saving space.
• Safety: Made of materials that meet safety standards, guarantees reliable operation and long life.
• Wire cross-section: Supports wires with a cross-section of up to 35 mm², allowing connection of both solid and stranded and flexible wires.

It is worth remembering that proper selection of a surge arrester is crucial to ensure effective protection. The C50-0-255 insert is a solid choice for installers looking for a reliable solution to protect against the effects of overvoltages in various types of buildings and electrical installations. Thanks to its versatility and high technical parameters, it provides peace of mind for both end users and professionals responsible for the safety of electrical installations.
