Motor and Circuit Safety – NH000 aM 50A/690V Fuse Link

The NH000 aM 50A/690V fuse link is a reliable protective element dedicated to protecting motors and electrical circuits from the effects of short circuits. Designed by ETI Polam, it meets the requirements of IEC 60269 and is characterized by high efficiency in interrupting short-circuit currents.

Protection and Status Indication

The construction of the fuse link is based on the aM characteristic, which means it is particularly well suited for protecting electric motors. In the event of an overload or short circuit, the fuse link blows, interrupting the circuit and protecting the connected devices. The "KOMBI" version is equipped with a double action indicator – both a traditional spring clip on the top cover and a red eye on the ceramic body. This system ensures quick and easy identification of a blown fuse, minimizing downtime of the installation.

Construction and Application

The NH000 aM 50A/690V fuse link is designed for operation in alternating current (AC) circuits with a rated voltage of up to 690V. The rated current is 50A. This element is intended for use with additional overcurrent protective devices, as it has a non-full-range breaking capacity. Using an aM fuse link allows for effective protection of contactors, relays and electric motors against damage caused by short circuits. Its compact size (NH000) makes it easy to install even in tight spaces.

Protection of electric motors, contactors and relays is ensured by the aM characteristic, which optimizes protection against the effects of short circuits in motor circuits. The KOMBI action indicator allows for quick identification of a blown fuse. The rated voltage is AC 690V, and the rated current is 50A. The fuse link finds application in industrial electrical installations.
