Circuit breakers are an important component in the safe operation of electrical systems. The T21-62-3.00A-23195-71-V is one such type of circuit breaker, and it has special characteristics which make it suitable for certain applications. The purpose of this article is to discuss the application field and working principle of the T21-62-3.00A-23195-71-V circuit breaker.

The T21-62-3.00A-23195-71-V circuit breaker is primarily designed for use in consumer safety protection systems, such as household fuse boxes and lighting circuits. It is designed to protect against overload, short-circuit and earth leakage. It also features an adjustable, anti-trip delay feature, which allows the associated circuit to remain active for a selectable period of time. This feature is especially useful in motor circuits and other applications where frequent startups may cause a momentary current surge.

The operation of the circuit breaker is based on two principles: thermal and magnetic. The thermal element senses the current flowing through the circuit and converts this into heat. This heat causes an internal bi-metallic element to expand, which in turn trips the breaker if the current flow exceeds the rated level. The magnetic element senses the current as a magnetic field and trips the breaker if the intensity of the magnetic field overwhelms the threshold level. This is useful in protection from short-circuit and earth-leakage conditions.

The T21-62-3.00A-23195-71-V is a DIN-rail mountable circuit breaker, which reduces installation and maintenance time. Its structure is rated for increased operational safety, and it is certified to the IEC 60947-2 standard. It is suitable for use in single-Phase 230V AC systems and is able to interrupt up to 3000 A in the presence of rated operational conditions.

The T21-62-3.00A-23195-71-V circuit breaker is a vital component in providing safe and reliable protection for electrical systems. It combines the advantages of thermal and magnetic trip functions, and is suitable for single-Phase 230V AC applications. With its adjustable anti-trip delay, it is an ideal solution for motor circuits and other high-startup current applications. The DIN-rail mounting and increased safety structure make it easy to install and maintain, and its IEC 60947-2 certification makes the T21-62-3.00A-23195-71-V a reliable choice for safe electrical protection.
