Fuse link - NH000 aM 32A/690V - motor rated 004181408

Professional protection for electric motors

The NH000 aM 32A/690V fuse link is a specialized solution designed by ETI POLAM for protecting motor circuits from the effects of short circuits. It features an aM characteristic, which means partial-range protection specifically adapted for operation with motor loads.

Operating parameters and performance

The device operates at a rated current of 32A and a rated voltage of 690V AC, allowing for its application in most standard industrial installations. A breaking capacity of 100kA at 690V AC guarantees effective interruption of even very high short-circuit currents, thereby protecting the entire installation from serious damage.

The NH000 size (also known as NH00C) ensures compatibility with standard fuse bases, facilitating replacement and maintenance. The industrial-type ceramic construction guarantees resistance to high temperatures and harsh environmental conditions typical of industrial environments.

Construction and signaling system

The link is equipped with a dual combined indicator, which enables quick identification of the device's status both visually and mechanically. This innovative signaling system allows for immediate recognition of fuse operation, which significantly accelerates the diagnostic and service process.

The knife-edge design allows for secure mounting in specially designed fuse bases using an insulating handle, ensuring a stable electrical connection throughout the entire service life.

Application and compatibility

The product belongs to the popular WT-NH series, which has been recognized by professionals since 1997. This link finds particular use in protecting contactors, starters, and electric motors of various power ratings, where protection against short circuits is required while simultaneously allowing for the normal startup of motor loads.

The aM characteristic ensures that the device reacts more slowly to short-term current surges accompanying motor startup, while providing an immediate response to actual short-circuit conditions.
