Surge protective device Type 1+2 (BC) 37.5kA 3P DS133R-230 C571503

Protection of electrical installations and devices

The surge arrester Type 1+2 (BC) DS133R-230 is a key element in protecting electrical installations from the effects of lightning strikes and voltage surges in the network. The device effectively protects against damage to electrical and electronic equipment, minimizing the risk of failure and costly repairs. This is particularly important in residential, commercial and industrial buildings where sensitive devices are commonly used.

Design and application

This surge arrester combines the features of Type 1 and Type 2 arresters, providing comprehensive protection. Type 1 protects against direct lightning strikes, and Type 2 – against overvoltages resulting from indirect discharges or switching in the network. The three-phase design (3P) makes these arresters ideal for protecting entire electrical circuits in buildings. The operating voltage of 230V makes it compatible with most standard electrical installations.

Advantages and benefits

• High efficiency: The rated impulse discharge current of 37.5kA guarantees effective protection even with strong surges.
• Versatility: The combination of class 1 and 2 provides a wide range of protection for different types of overvoltages.
• Durable construction: Made of high-quality materials, ensuring reliable operation for a long time.
• Easy installation: Compact dimensions facilitate installation in electrical switchboards. The IP20 degree of protection ensures safe use in standard environmental conditions.
• Compliance with standards: The arrester meets the required safety standards, confirming its quality and reliability.
• Protection for the installer and user: Protecting the installation from damage translates into lower service costs for the installer and peace of mind for the end user.
