Electrical, Specialty Fuses

A specialty fuse is an electrical device designed to warm and disconnect electrical circuits when an overload or short circuit occurs. The 170M8646 is a specialty fuse manufactured by Semikron, a renowned manufacturer of power semiconductors. This fuse offers reliable AC and DC switching protection for inverters, converters, controllers, and other power electronics.

Application Field

The 170M8646 fuse is ideal for protecting input and output circuits for inverters, converters, controllers, and power supplies for applications such as home automation, aircraft, industrial equipment, and motor control. It is designed to provide an additional measure of safety to help protect against the risk of fire or damage to equipment from electrical overloads and shorts.

Working Principle

The 170M8646 works by detecting when an increase in current flow through the circuit occurs. When this happens, a magnetic field is created that forces an internal contact in the fuse to close. This initiates the heating process in the fuse, which eventually causes the fuse wire to heat up and melt, thereby opening the circuit and disconnecting the power. Once the circuit is disconnected, the fuse must be replaced before power can be restored to the circuit.

The 170M8646 has a high thermal release temperature and is rated for a maximum current of 63A. Additionally, it is UL-listed and compliant with IEC60715 standards and operates between -40°C and +50°C. It is available in a variety of sizes and configurations, making it ideal for a variety of applications.

The 170M8646 is a reliable specialty fuse. It provides efficient and reliable protection against electrical overloads and short circuits. It is simple to install and maintain, and its durable construction ensures it will perform reliably and safely for many years.
