What Is SSQ 8 Application Field And Working Principle

SSQ 8 is a type of fuse commonly used in industrial and commercial systems to protect electrical components and circuits during a short circuit or other fault. In contrast to a circuit breaker which is designed to interrupt a load only in the event of an overload or short circuit, a fuse must be replaced after it has operated. SSQ 8 fuses are designed specifically to ensure a sufficient level of safety in electrical systems with a large current surge; they also act as a protection device for people, property, and equipment in the event of a line short or overload.

Application Field

The SSQ 8 fuses are mainly used in three fields. The first field is industrial control systems. SSQ 8 fuses are often used in various power systems such as variable-frequency drives (VFDs), contactors and circuit breakers to protect the system from a surge or over-current. The second field is HV/LV power distribution, in which case the SSQ 8 fuses are used to provide a stable electrical flow and to protect against over-current. Lastly, SSQ 8 fuses are also used in the automotive industry for devices such as starter circuits and other switches to isolate the car\'s electrical components from any potential short circuit.

Working Principle

When a fault occurs, the current flow in the circuit increases, causing an increase in the temperature of the fuse wire. This increase in temperature leads to the melting of the fuse wire, interrupting the current flow. When the temperature of the fuse wire reaches 450°C, the metallic material used to construct the fuse melts and creates a gap in the circuit, allowing the current flow to stop. The melting process also expels debris and molten material to protect other components in the circuit. Once the fuse has been triggered, it cannot be reset and will need to be replaced with a new fuse. SSQ 8 fuses are designed to break the circuit quickly and effectively during short circuit or overload conditions.

Safety and Protection Features

The safety and protection features of SSQ 8 fuses make them ideal for industrial and commercial applications. The fuse wires are made of an electrically-resistant material which reduces the risk of a short circuit in the circuit and the explosive gas created by the wire melting exactly like the circuit breaker. In addition, SSQ 8 fuses also have an overload protection feature which prevents the fuse from tripping during normal operating conditions, only when the current draw is too great. Finally, SSQ 8 fuses can also provide a degree of protection against shock hazards and can limit the current flow to prevent personal injury.

Conclusion

The SSQ 8 type of fuse is an essential component for any industrial or commercial application, providing essential safety and protection. With its high melting temperature, overload protection features, and shock hazard protection, the SSQ 8 fuse is the ideal choice for any application requiring reliable and safe protection. From variable-frequency drives (VFDs) to HV/LV power distribution, the SSQ 8 fuse can help protect users, property, and equipment from a short circuit or overload.
