Fuse link - NH2 aM 400A/690V - motor starter 004185424

Installation and motor safety – NH2 400A fuse link

This NH2 fuse link with a rated current of 400A and a voltage of 690V, manufactured by ETI Polam, is a key element in protecting electrical installations, especially those powering motors. Designed to protect against the effects of short circuits and overloads, it ensures reliable operation of devices and minimizes the risk of failure.

This fuse link is characterized by a construction dedicated to motor protection – aM classification (motor short-circuit protection) according to IEC 60269. This means that it can withstand short-term current surges that occur during motor start-up, while providing a quick response in the event of more serious short circuits. This protects not only the motor but also the entire electrical installation from damage.

Construction and functionality

The fuse link is equipped with a dual operating indicator – combined. It allows for quick visual identification of a blown fuse, which greatly facilitates locating and resolving failures. The lack of metal insulated grips (IMGL) indicates a standard construction, compatible with most NH2 fuse holders available on the market. This solution simplifies replacement and servicing.

Application and benefits

• Motor protection: aM class provides optimal protection for electric motors against overloads and short circuits.
• Fast fault identification: The combined operating indicator makes it easy to locate a blown fuse.
• Versatility: Compatibility with standard NH2 holders simplifies installation and replacement.
• Reliability: Production by a reputable manufacturer – ETI Polam – guarantees high quality and durability.
• Safety: Provides effective protection of the electrical installation against the effects of short circuits and overloads – like most circuit breakers in this class.

The NH2 400A/690V aM fuse link is a solid solution for professionals and end-users looking for reliable protection of their electrical installations powering motors. Its technical parameters and construction guarantee long-term and efficient operation, minimizing the risk of downtime and costly repairs.
