Fuse link - NH2C aM 250A/690V - motor starter 004185419

Installation and motor safety – NH2C 250A fuse link

The NH2C 250A/690V fuse link is a reliable element protecting electrical installations, especially circuits powering motors. Designed to work with alternating current (AC), it provides effective protection against overloads and short circuits, minimizing the risk of damage and downtime. Its aM (motor) characteristic makes it ideal for applications requiring high selectivity and resistance to inrush currents generated during motor starting.

Design and application

The fuse link manufactured by ETI POLAM, a renowned manufacturer of electrical installation equipment, is characterized by a solid construction and high quality workmanship. Designed for mounting in dedicated NH2C fuse holders, it is an integral part of protection systems in commercial buildings, industrial plants and energy infrastructure. The operation indicator – combined (double) – facilitates quick identification of a blown fuse, which translates to minimal repair time and re-launch of the installation.

Key features and benefits

• Motor protection: The special aM characteristic provides optimal protection of electric motors against the effects of overloads and short circuits, which extends their lifespan and reduces operating costs.
• High rated current: The rated current of 250A allows for the protection of circuits with significant power, making it an ideal solution for demanding industrial applications.
• Rated voltage 690V: The possibility of use in installations with a voltage of up to 690V ensures a wide range of compatibility with various power systems.
• Operation indicator: The combined operation indicator facilitates quick diagnosis of damage and location of the problem in the installation.
• No metal insulated grips (IMGL): The lack of IMGL simplifies the installation and removal of the fuse link, especially in tight spaces of switchboards.
• Compliance with standards: The product meets the stringent safety standards of IEC 60269, guaranteeing reliable operation and safety of use.
