Surge arrester Type 1+2+3 100kA 3+1p DS254VG-300/G C2756

Protection of electrical installations with surge limiters DS254VG-300/G

The DS254VG-300/G surge limiter is an advanced device designed to protect electrical installations from the effects of atmospheric and switching surges. Its 3+1p construction (i.e. 3 phases plus neutral) makes it an ideal solution for TT-TNS networks, providing comprehensive protection against both direct and indirect lightning strikes. This is a class 1+2+3 device, which means it effectively suppresses both strong lightning impulses (class 1) and less intense transient overvoltages (classes 2 and 3).

VG technology and its advantages

The use of VG technology in the DS254VG-300/G limiter translates into exceptional durability and reliability. This technology is based on a combination of a spark gap and a varistor, which ensures a fast response to overvoltages and a high ability to absorb energy. Thanks to this, these limiters are characterized by a long service life and minimal degradation of parameters during operation. This is particularly important in installations requiring a high level of safety and continuity of power supply.

Parameters and application

The DS254VG-300/G limiter is adapted to work in TT-TNS network systems, offering an impulse current Iimp at the level of 100kA (10/350 ms). This means that it is able to effectively dissipate energy even from very strong surges. Use in residential, commercial and industrial installations guarantees protection of sensitive electronic equipment from damage caused by disturbances in the power supply network. Installation of this type of limiter is crucial to ensure the safety of people and the protection of property.

• Versatility: The limiter works perfectly in various types of electrical installations.
• High efficiency: The ability to absorb impact energy at the level of 100kA ensures effective protection against strong surges.
• Durability: VG technology guarantees long life and stable operating parameters.
