Knife link – reliable connection in high-current installations

The NH1 250A Hager Polo knife link is an element used to safely and precisely connect electrical circuits with high current intensity. The design of the link allows for temporary short-circuiting or bypassing of protections, which is particularly useful during service work, tests, and in situations requiring flexibility in energy management. Made of high-quality materials, it guarantees durability and reliability even in demanding industrial conditions.

Construction and application

The LNH1TM link is characterized by a solid construction and the use of silver-plated contacts. Silver is a metal with excellent electrical conductivity, which minimizes connection resistance and reduces heating of the element during operation. The NH1 size ensures compatibility with a wide range of standard fuse bases and disconnectors, making it easier to integrate with existing installations. The rated current of 250A makes this link perfect for applications requiring high current throughput.
