Surge limiter insert type V50-0-150 5093505

Surge protection in electrical installations

This V50-0-150 surge limiter insert is a key element ensuring the safety and reliability of electrical installations. Designed to protect against the effects of lightning strikes and other surges, it minimizes the risk of equipment damage and ensures uninterrupted power supply. It is a Class 1+2 component, which means it effectively works both in the event of direct lightning strikes and indirect surges.

Construction and application

The insert is designed for mounting on a DIN TH-35 mm mounting rail, which facilitates its installation and replacement. Its compact size – only 1 module – allows for efficient use of space in the switchgear cabinet. It finds application in residential, commercial and industrial buildings, where protection against surges is particularly important. Thanks to its high surge current capacity (12.5 kA at 10/350 µs), it effectively protects circuits against overload and short circuit. Optical indication of operation allows for quick identification of a faulty element and the need for its replacement.

Key features and benefits

• Versatility: Compatible with various network systems – TN, TN-C, TN-C-S, TT – making it a universal solution for many installations.
• High efficiency: Protection level of 0.8 kV for L-N and N-PE provides effective protection against surges of various origins.
• Safety: Made of self-extinguishing plastic (UL 94 V-0), minimizes the risk of fire spreading in the event of a failure.
• Easy replacement: Replaceable insert with a dynamic disconnecting device facilitates servicing and reduces repair costs.
• Large wire cross-section: Supports wires with a maximum cross-section of 35 mm² (both solid/stranded and flexible) allowing connection to a wide range of installations.
• Mechanical protection: It has a mechanical locking of the inserts protecting against falling out caused by vibrations and voltage coding preventing incorrect installation.
• Compliance with standards: Meets safety standards, guaranteeing reliable operation and protection of the electrical installation.
