Surge arrester Type 1+2+3(BCD) 50kA 4P DS134VGS C571574

Protection of electrical installations with surge arrestors

The DS134VGS surge arrester is a comprehensive solution providing protection against the effects of lightning strikes and surges in electrical installations. The Class 1+2+3 (BCD) device effectively protects against impulsive voltage increases, minimizing the risk of equipment damage and ensuring uninterrupted power supply. The four-pole design makes these arrestors ideal for protecting three-phase circuits.

Construction and application

This arrester combines three levels of protection – Type 1, Type 2 and Type 3 – making it a versatile element of the surge protection system. Type 1 protects against direct lightning strikes, Type 2 reduces voltages resulting from indirect discharges, and Type 3 provides additional protection for sensitive devices. Mounting on a 35 mm DIN rail facilitates integration with existing electrical infrastructure. The use of the arrester is crucial in residential, commercial and industrial buildings, where protection against surges is essential for the reliable operation of electrical systems.

Key features and benefits
