Fuses are essential in almost all electrical systems; they are a critical protection device, because they are designed to help prevent overloads and short circuits. A fuse at its most basic form is simply a strip of metal with a wire attached to it. When the current running through the fuse exceeds its given threshold, the metal strip ‘melts’ or ‘burns’, effectively cutting the electrical circuit. This helps prevent further damage being done to the system or any electrical device.

SSQ 2 Application Field and Working Principle

The SSQ 2 is a low voltage fuse, specifically designed for use in sensitive automotive environment where safety is a priority. It is typically used in motor control and safety applications. This type of fuse is commonly found in control systems, airbags, power steering, and ABS systems. The SSQ 2 fuse combines several fusing and protection functions into one element, making it an ideal choice for protection in these applications.

The SSQ 2 fuse utilizes two separate current-level sensing elements. The first sensing element is used to detect an over-current situation and will trigger a fuse-trip in case of a short-circuit or sustained overload condition. The second sensing element in the SSQ 2, monitors current levels below the trip level to detect any inrush current or motor start-up current. This additional level of protection helps prevent the fuse from tripping during start-up conditions, avoiding unnecessary nuisance tripping and reducing operational downtime.

The SSQ 2 also features a reset switch which can be used to manually reset the fuse if necessary. This additional feature provides an extra safety feature, helping to ensure the circuit is not overloaded or damaged before it can be reset.

The SSQ 2 fuse features a patented technology which enables it to discriminate between normal motor start-up current and dangerous over-currents. This helps to ensure the fuse does not malfunction during motor start-up, while still providing the necessary protection against over-currents and short circuits.

The SSQ 2 fuse offers a high level of protection in a variety of applications and is a critical safety feature for modern car electronics. It can provide a robust and reliable solution for most power and motor control applications and is a smart choice for those looking for reliable and robust protection.
