A fuse is an electrical device designed to protect an electrical circuit from excessive current by melting, opening an electric circuit or de-energizing an electric device. SSQ 800/1K Fuses have voltage ratings of 800V or 1000V and a current rating of 32A-80A.

These fuses are widely used in industrial, commercial, and residential applications. Applications for SSQ 800/1K fuses include motor protection, appliance and equipment protection, over-current protection, and lighting protection. In motor protection applications, these fuses are used to protect the motor from over-current and short-circuits. In appliance and equipment protection applications, these fuses protect against a short circuit or overload from an over-current situation.

The working principle of SSQ 800/1K fuses is based off of current sensing technology. Current sensing technology enables these fuses to detect fluctuations in current and react quickly to open the electric circuit. The current sensing technology works by utilizing an embedded magnet and an iron core in the contacts of the fuse. The magnetic field created by the contact is inversely proportional to the current flowing through the circuit. If the current passing through the circuit rises to an unsafe level, the magnetic field will cause the contacts to melt and separate, interrupting the current flow.

The availability of SSQ 800/1K fuses in both high and low voltage ratings also make them ideal for applications such as solar power, residential and commercial power, and automotive applications. Solar power applications require low voltage fuses to protect inverters and modules. Residential and commercial applications require SSQ 800/1K fuses as they can detect faults before they become larger issues, which prevents fire and other costly damage. Automotive applications use these fuses as they are also able to sense and respond to low level current.

Overall, SSQ 800/1K fuses are a cost-effective and easy to install solution for over-current protection. They can be used in a variety of applications and their current sensing technology ensures they can react quickly and accurately to prevent risk and damage from over-current conditions. The availability of these fuses in both high and low voltage ratings make them ideal for use in a range of applications.
