Cylindrical fuse link CH14x51 aM 8A/690V 002652027

Safety and protection of electrical installations

Cylindrical fuse link CH14x51 aM 8A/690V is a protective element that protects electrical circuits from the effects of overloads and short circuits. Its task is to quickly disconnect the power supply in the event of a dangerous increase in current, minimizing the risk of damage to equipment and preventing fires. This particular fuse link, with aM characteristic, is especially recommended for protecting electric motors – it allows for short-term exceeding of the nominal current, which is typical during engine start-up, without unnecessarily disconnecting the circuit.

Characteristics and application

The CH14x51 aM 8A/690V fuse link is designed for use in electrical installations with a voltage of up to 690V. Its dimensions – 14x51 mm – are a standard for cylindrical fuse links, ensuring compatibility with a wide range of switchboards and fuse holders. The aM characteristic (compliant with IEC 60269 standard) means that this fuse link has a delayed response to current flow, which is crucial when protecting circuits with motors or other devices generating high inrush currents during start-up. This avoids unwanted shutdowns caused by momentary current surges.

Construction and mounting

ETI Polam cylindrical fuse links are characterized by a solid construction and high quality workmanship. The body made of C110 or C410 porcelain provides electrical insulation and resistance to environmental conditions. Contacts made of CuZn28 coated with silver (Gal.Ag) guarantee good electrical contact and minimize power losses. Mounting the fuse link is simple and intuitive – just place it in the appropriate fuse holder. It is important to select the correct fuse link for the protected circuit, taking into account the characteristic, rated current and operating voltage of the installation.
