Surge arrester, 3p Type 2 (class C) type V20-3-150 5095153

Electrical installation protection – reliable surge protector

This three-pole type 2 surge protector, class C, is a key element ensuring the safety and continuity of the electrical installation. Designed for mounting on a TH-35 mm DIN rail, it effectively protects against the effects of surges that can damage sensitive electrical equipment. Its design and parameters make it an ideal solution for both installers and end users.

This surge protector has been designed to equalize potentials in overvoltage protection, in accordance with VDE 0100-443 (IEC 60364-4-44). The ability to discharge a surge current of up to 40 kA (8/20) per pole, thanks to the use of high-performance varistors, guarantees effective protection against sudden voltage spikes. Short-circuit strength at 20 kA further increases its reliability in difficult working conditions.

Application and design features

The surge protector is widely used in main and sub-distribution boards. Its compact size – only 3 modules – makes it easy to install even in limited spaces. The housing made of self-extinguishing plastic (UL 94 V-0) ensures fire safety. Optical indication of operation allows for quick identification of damage and the need to replace the insert. Additionally, mechanical locking of the inserts protects against the effects of vibration and provides voltage coding for correct configuration.

• Versatility: compatible with TN, TN-S and TN-C-S and TN-C systems

• Effective protection: protection level up to 0.8 kV (L-N) and 20 kV (N-PE) minimizes the risk of damage

• Easy installation: mounting on a standard TH-35 mm DIN rail

• Durable construction: housing made of self-extinguishing plastic ensures safety

• Quick diagnostics: optical indication of the device status facilitates problem identification

• Wire cross-section: possibility to connect wires with a maximum cross-section of 35 mm² (flexible and single-/multi-stranded)

Thanks to this surge protector, the reliability of the electrical installation can be significantly increased and costly failures caused by surges can be avoided. It is an investment in safety and peace of mind for both professionals and end users.
