Fuses are an integral part of electric vehicle (EV) systems. By providing an electrical connection between the EV’s battery and its motor, they ensure that the current flow is appropriately managed and protected against potentially damaging components. A sub-set of those fuses, the SSQC7, is used in a wide variety of EVs. In this article we’ll discuss the application field and working principle of the SSQC7.

The SSQC7 is a mid-voltage fuse designed for use in EVs. It is used to protect the vehicle’s electrical system from overcurrent, preventing damage to the components and ensuring that the current flow is appropriately managed. The SSQC7 is suitable for a wide range of applications, from small passenger vehicles to large commercial EVs. In addition, its small size and light weight make it ideal for use in small spaces.

The working principle of the SSQC7 is relatively simple. When an excessive amount of current flows through the system, the fuse will break the connection, preventing further damage to the system. This is achieved by the fuses’ metal contacts being heated by an arc. The arc will cause the fuse’s contacts to open, cutting off the flow of current and protecting the system.

The SSQC7 is capable of enduring high temperatures, providing extra protection against over-heating. This is achieved by a heat-sensitive bimetallic strip. When the temperature of the system exceeds the designed limit, the bimetallic strip will expand, causing the fuse contacts to open and prevent further damage to the system.

The SSQC7 can also be used in a variety of current sensing applications. This is achieved through its three-pole contacts. When current flows through the terminals, a magnetic field is generated. This field will act on the contacts, causing them to open, thus increasing the resistance and limiting the amount of current flowing through the system.

The SSQC7 is also designed to be used with ground fault circuit interrupters (GFCI), providing additional protection against potentially hazardous faults. By wiring an SSQC7 in series with a GFCI, any dangerous faults will be detected and the flow of electricity interrupted before any serious harm can be done.

To sum up, the SSQC7 is a useful and reliable component for electric vehicle systems. Its small size and light weight make it ideal for a variety of applications, from large commercial EVs to small passenger vehicles. It is also capable of enduring high temperatures and can be used in a variety of current sensing applications, providing valuable protection against overcurrent and ground faults. By utilizing the SSQC7, electric vehicle owners can rest easy knowing that their systems are being properly protected.
