Fuses

0HEV020.SXBD application field and working principle

Fuses are an important safety device for an electrical system. In a vehicle, they are commonly found in the powertrain and human power machine systems. The most common fuse type in use in the automotive industry is the 0HEV020.SXBD.

The 0HEV020.SXBD is an automotive type fuse, which is a type of fuse specifically designed for the automotive industry. This type of fuse is a combination of a thermal fuse and a circuit breaker. The 0HEV020.SXBD is primarily designed to protect from severe electrical overloads, simultaneously offering protection from short circuits and current fluctuations. The 0HEV020.SXBD is a dual level protection device. The thermal fuse reacts to temperature by providing fusing at a set temperature, and the circuit breaker is a low-voltage tripping device.

The 0HEV020.SXBD is typically applied in circuits with wire sizes ranging from 0.2mm (8 AWG) to 1.5mm (14 AWG). It is the most common size in the automotive industry, and is generally used in car, truck or motorcycle electrical systems. The maximum rated current capacity of this type of fuse is 2A. The 0HEV020.SXBD has a rated current at 125V and also has high-temperature protection, which has a maximum voltage rating of up to 500V.

The working principle of the 0HEV020.SXBD is simple. The fuse is placed in the circuit with a specified current limit. When too much current tries to flow through the fuse, it reaches its thermal limit and melts, thereby breaking the circuit and cutting off the current flow. This breaking of the circuit protects any circuits or components in the system.

In conclusion, the 0HEV020.SXBD is a type of automotive fuse designed for vehicles. It is a combination of a thermal fuse and a circuit breaker, and is used to protect electrical systems from overloads and short circuits. It is a dual level protection device. The maximum current capacity of this type of fuse is 2A, with a rated current of 125V. The working principle is simple, and when too much current flows through the fuse, the thermal fuse melts, breaking the circuit and cutting off the current.
