The Mersen NH1 Fuse link - 200A, 690V are partial-range breaking capacity fuse-links, used to protect motor circuits as they are strongly current-limiting and have low power losses. They interrupt currents from 6.3 times In up to their maximum breaking capacity and are therefore suited for short-circuit protection only. They must be associated with other switchgear for protection against overloads. These fuse-links can have a rated current equal to the motor's nominal current.
Application:
aM: Partial purpose, motor circuit protection
Please Note:
Since the design of this system cannot guarantee non-interchangeability of rated current, it must be handled by a qualified professional.
