Circuit breakers are electrical devices used to protect machines and electrical systems from potentially dangerous levels of power overloads. They work by tripping or automatically shutting off power before the circuit experiences too much voltage. By breaking up the electrical circuit, circuit breakers prevent overload and possible fire hazard. They are used in many different types of commercial and residential applications.

Type 203-2-3934-4 is a special three-phase circuit breaker, which has an asymmetrical electrical configuration. This circuit breaker is designed specifically for applications where the motor and breaker system need higher thermal protection and breaker reliability. It is typically used for residential, commercial, industrial, and other types of applications.

The type 203-2-3934-4 circuit breaker works by monitoring the over-voltage current of a circuit. If the current increases beyond a certain level, the breaker will trip and shut off the power. Additionally, the breaker will monitor the under-voltage current of a circuit and will trip, when it decreases below a preset level. This helps protect circuits from dead shorts and potential fires.

The 203-2-3934-4 circuit breaker also helps protect against power surges, which would otherwise cause damage to electrical equipment and other sensitive components. It is designed to be shockproof, and includes over-temperature protection and short-circuit protection as standard features. Additionally, the breaker is equipped with an adjustable current-limit setting, which allows for current levels to be adjusted in the event of significant changes in power usage.

The 203-2-3934-4 circuit breaker is designed to conveniently reset itself, and it can operate in both equilateral and asymmetric current modes - allowing for a higher degree of safety and reliability. This breaker also features high-speed short-circuit protection and is temperature-resistant. This helps provide greater power protection for any circuit, regardless of the voltage or current levels.

In summary, the 203-2-3934-4 circuit breaker is a highly advanced device that provides superior power protection for a wide range of residential, commercial, and industrial applications. It is designed to detect over-voltage and under-voltage current, as well as provide protection from power surges. Additionally, this breaker comes with adjustable current-limit settings and high-speed short-circuit protection. Lastly, it is shockproof, temperature-resistant, and conveniently resets itself in the event of a power overload or surge.
