Surge arrester 4P, Type 2+3 (class C+D) type V10-C 3+NPE-320 5094924

Electrical installation protection with surge limiters V10

The V10-C 3+NPE-320 surge limiter is a reliable element protecting electrical installations from the effects of atmospheric overvoltages and network disturbances. The device is designed for mounting on a TH-35 mm DIN rail and offers comprehensive protection in TN-S, TN-C-S and TT network systems. Its 4-pole (4P) design makes it an ideal solution for circuits requiring full protection, and the optical signaling of the device's status facilitates quick identification of any failures.

Construction and application

This limiter combines the features of type 2 and 3 protection, which means it effectively suppresses both lightning strikes with high energy and smaller disturbances occurring in everyday use. The use of a thermal and dynamic disconnecting device provides additional safety, automatically disconnecting the limiter in the event of exceeding the permissible parameters. This protects not only the installation itself, but also the devices connected to it.

This limiter finds wide application in residential buildings, single-family homes, as well as in commercial and industrial facilities. Its compact size (4 modules) allows for easy installation even in limited space of the switchgear. The maximum wire cross-section of 35 mm² allows connection of both solid and stranded wires.

Key features and benefits

• Versatility: Compatible with TN-S, TN-C-S and TT network systems – one limiter for different installation configurations.
• High efficiency: Rated discharge current up to 20 kA (8/20) provides effective protection against lightning strikes and overvoltages.
• Status indication: Optical indication of damage facilitates quick identification of the need for replacement.
• Safety: Thermal and dynamic disconnecting device provides additional protection against overloads and short circuits.
• Easy installation: Compact size (4 modules) and mounting on a TH-35 mm DIN rail facilitate installation.
• Durability: High electrical conductivity guarantees long device life.
• Universality: Adapted to wires with a maximum cross-section of 35 mm².
• Protection level: Provides a protection level of up to 1.2 kV – high resistance to impulse voltages.

The V10-C 3+NPE-320 surge limiter is an investment in the safety of your electrical installation and connected devices. It provides peace of mind and minimizes the risk of costly failures caused by overvoltages.
