Blade switch insulated NH3 630A silver-plated contacts LNH3TM

Insulated knife connector – reliable connection in medium voltage installations

The insulated NH3 knife connector with a rated current of 630A is a key element for safe and efficient connection of conductors in medium voltage switchgear. Made of high-quality materials, it provides a stable connection and minimizes the risk of failure. Silver-plated contacts guarantee excellent conductivity and corrosion resistance, which translates to long-term reliability.

This model, designated LNH3TM, is designed for applications requiring high mechanical and electrical resistance. It is ideal for both new installations and modernization of existing systems. Its construction ensures easy assembly and disassembly, which significantly facilitates service and maintenance work.

Construction and characteristics

The NH3 connector is characterized by a solid, insulated construction, ensuring safe use. The rated current of 630A makes it suitable for protecting circuits with a high load. A power loss of 9.1W at the rated current indicates high energy efficiency. Silver-plated contacts minimize transition resistance, reducing energy losses and preventing overheating of connections. The use of high-quality insulating materials guarantees protection against electric shock and ensures durability in harsh environmental conditions.

The use of insulated knife connectors in medium voltage installations is an industry standard, ensuring the safety and reliability of the entire system. Thanks to precise workmanship and the use of advanced technologies, Hager connectors meet the highest quality standards.
