Surge protection plug PRD125r-T1-L-INS 16315

Electrical installation protection with surge limiter PRD125r-T1-L-INS

The PRD125r-T1-L-INS surge limiter insert is a key element in protecting the electrical installation from the effects of surges, both resulting from lightning strikes and induced by devices inside the building. Designed to work with TN and TT networks, it provides effective protection against equipment damage and power outages.

Characteristics and application

This type 1 surge arrester, with a protection level of 1.5 kV, is used in residential, commercial and industrial buildings. Its task is to discharge excess energy to the ground in the event of a surge, protecting connected devices from damage. Optical signaling informs about the operation of the arrester, making it easier to identify potential problems. Mounting is done on a base - which simplifies installation and replacement.

Advantages and benefits

• The arrester provides effective protection thanks to the rated discharge current reaching 25 kA, guaranteeing high resistance to strong surge pulses.
• Its versatility results from the possibility of use in TN and TT network systems, which increases the range of compatibility with different types of installations.
• Optical indication of operation facilitates quick diagnosis and replacement, saving time and service costs.
• Compliance with safety standards confirmed by the CE marking ensures reliable operation and minimizes the risk of failure.
• Mounting on a 35 mm DIN rail facilitates integration with existing electrical infrastructure, ensuring simple installation.
• The lack of an integrated short-circuit protection requires the use of additional protection in the installation (e.g. fuses), which must be taken into account when designing the protection system.
• The rated AC voltage of 230 V makes it an ideal solution for standard electrical installations.
• The maximum continuous operating AC voltage of 350 V ensures stable operation under normal operating conditions.
• The degree of protection IP20 provides protection against touching with fingers and solid objects larger than 12.5 mm, which is suitable for mounting inside distribution boxes.
