Motor and Circuit Safety – NH1 aM 35A/690V Fuse Link

This NH1 aM 35A/690V fuse link is a reliable protective element dedicated to protecting motors and circuits from the effects of short circuits. Designed to work with relays, contactors and motors, it provides a quick response in the event of a failure, minimizing the risk of damage and downtime. Its aM characteristic, compliant with IEC 60269, makes it ideal for applications requiring protection against overloads and short circuits in motor circuits.

Construction and application

The fuse link manufactured by ETI Polam in size NH1 operates at a rated voltage of 690V AC and a rated current of 35A. The "KOMBI" version is equipped with a dual operating indicator – standard (spring blade) and optical (red eye), which facilitates quick identification of a blown fuse. This solution is particularly useful during inspections and maintenance of electrical installations. It is worth remembering that a fuse with aM characteristic requires cooperation with an additional overcurrent device due to its non-full-range breaking capacity.

Advantages for the installer and end user

• Fast burnout identification: The dual operating indicator (KOMBI) allows for immediate detection of damage without the need to disassemble the fuse.
• Protection of motors and contactors: The aM characteristic provides effective protection against short circuits in motor circuits, which translates into a longer lifespan of devices.
• Compliance with standards: The fuse meets the requirements of IEC 60269, guaranteeing safety and reliability.
• High short-circuit strength: The short-circuit breaking capacity at 100kA provides effective protection even in the event of high current flows.
• Clear status: The operating indicator informs about the need for replacement – it rises up and the red color disappears from the eye.

By choosing this fuse link, you are investing in the safety and reliability of your electrical installation.
