0TOO.500Z Application Field and Working Principle

0TOO.500Z is a kind of special fuse which can be widely used in voltage regulating, DC drive, AC drive, transformer output, motor generator, battery charging/discharging, remote control, sports machine, and so forth. This article is intended to describe the application field and the working principle of 0TOO.500Z.

Application Field of 0TOO.500Z

Generally, 0TOO.500Z can be used in applications within 690V and 250V AC, and rated current ranging from 500mA to 10A. It is suitable for voltage regulating, DC drive, AC drive, transformer output, motor generator, battery charging/discharging, remote control, sports machine, etc. The characteristics of the 0TOO.500Z allow it to effectively respond to current changes and abnormal events.

Here are two typical application fields of 0TOO.500Z:

• DC Drives: 0TOO.500Z can effectively protect DC drives from overload, overpressure, undervoltage, short circuit, and other faults.
• Motor Generators: 0TOO.500Z can protect the motor generators against overcurrent, overload, short circuit, and other faults.

The Working Principle of 0TOO.500Z

When an overload or short circuit appears, the current rating of 0TOO.500Z will be significantly higher than its normal rated value, which will generate a large overpressure inside the fuse, resulting in an an electrical arc between the contact points. After a certain period of time, the fuse will be extinguished and the fuse element will be separated from the contact points, thus cutting off the current.

When overvoltage or undervoltage occurs, the fuse element will react like a normal load, absorbing extra voltage. This will create a stronger field force between the contact points and the fuse element, thus allowing the fuse to respond to the voltage change. This will cause the fuse element to separate from the contact points to protect the target device.
