Fuse link - NH1 aM 250A/690V - motor starter 004184419

Motor and installation safety – NH1 250A aM fuse link

The NH1 fuse link with a rated current of 250A and aM characteristic is a reliable element protecting electrical installations and motors. Designed by ETI POLAM, a renowned manufacturer, it provides effective protection against the effects of short circuits and overloads. It is a key component for installers and users who care about safety and the continuity of device operation.

Protection tailored to motor needs

The aM (motor) characteristic makes this fuse link particularly recommended for protecting circuits powering electric motors. It allows for short-term exceeding of the rated current without unnecessary circuit disconnection, which is typical for starting motors – these devices need a temporary power reserve. At the same time, in the event of a serious short circuit, the fuse link will react quickly and effectively, cutting off the power and minimizing the risk of damage.

Construction and functionality

The fuse link is made of high-quality materials, which guarantees its durability and reliability. It is equipped with a double indication of operation, which facilitates visual control of the fuse link status – it allows you to quickly determine whether it has blown and needs to be replaced. Designed for operation in circuits with a rated voltage of 690V (AC). The lack of metal insulated grips (IMGL) means a standard construction, compatible with most switchgear.

Key features:

• Rated current 250A: Provides adequate protection for circuits with high current draw.
