Mersen NH1 Fuse link, 690V, 200A

With the Mersen NH1 Fuse link it's important to note that the NH system is a plug-in fuse system commonly used for protection against overloads and short-circuits in industrial applications.

The NH1 Fuse link you mentioned is rated for 690V and 200A. It's essential to understand that this fuse-link has a partial-range breaking capacity and is intended for short-circuit protection only. As such, it must be used in conjunction with other switchgear for protection against overloads.

Additionally, the NH1 Fuse link type "aM" is specifically designed for protecting motor circuits as it has low power losses and is strongly current-limiting. These fuse-links can have a rated current equal to the motor's nominal current, which makes them well-suited for motor circuit protection.

It's worth mentioning that the NH system is designed to be handled by qualified professionals because the design of the system cannot guarantee non-interchangeability of rated current. This means that special care must be taken to ensure the correct fuse-link is used for a particular application to avoid equipment damage or injury.

Overall, the Mersen NH1 Fuse link is a crucial component of the NH system, and it's essential to understand its capabilities and limitations to ensure safe and reliable operation in industrial applications.
