Fuses: SSQ 800/5K Application Field and Working Principle

Fuses are widely used in a variety of electrical fields for protection against unexpected electrical problems. This article will focus on the application field and working principle of the SSQ 800/5K fuse.The SSQ 800/5K is a high-current, low-voltage fuse. It is designed for use in applications requiring high overcurrent protection for medium-voltage motors, generators, and bus work. The SSQ 800/5K can be used in 600V AC and DC branch circuits and is suitable for use in individual machine and motor disconnects. It is also ideal for applications involving loads with varying inrush and locked rotor current ratings.The SSQ 800/5K is composed of three main components: a fuse body, a fuse element, and a fuse holder. The fuse body is made from a material which is both electrically and thermally conductive. This allows it to maintain a firm grip on the fuse element while dissipating heat away from the element. The fuse element is the part that connects the electrical circuit – it is made of a metal alloy that will break when the current reaches a certain level. The fuse holder serves to hold the fuse element securely in place.The SSQ 800/5K creates a short-circuit by breaking the fuse element when the electrical current exceeds a predetermined limit. The current will then flow around the arc-gap of the fuse, creating a conductive path. This will cause an increase in the resistance across the arc-gap, further increasing the resistance in the circuit and preventing any further current from flowing through the fuse. If the current remains within safe limits, the fuse element will remain intact.The SSQ 800/5K is suitable for a wide range of applications. Its main advantages are its small size, low cost, and high current-carrying capacity. The fuse is already pre-assembled and is easy to install in circuits. Additionally, the SSQ 800/5K offers quick response times to large overloads which helps to ensure the safety of both the operators and the equipment being protected.In conclusion, the SSQ 800/5K is a reliable and cost-effective solution for protecting low-voltage electrical circuits from unexpected current overloads. It is suitable for a wide range of applications and its quick response time helps to provide superior protection.
