Circuit breakers are essential components in electrical systems. By breaking the circuit, they protect components and personnel from being damaged or injured due to a power surge or short circuit. The 1Z25UM is a type of circuit breaker designed for medium and large installations. It is capable of simultaneous disconnection of the supply circuit in the event of a fault, which makes it suitable for applications where the supply needs to be disconnected quickly to avoid damage or harm. In this article, we will look at the application fields and working principle of the 1Z25UM.

The 1Z25UM circuit breaker is designed for use in medium and large installations that require protection from overvoltages, or from excessive current or earth fault current, arising from single-phase or three-phase currents. It is suitable for protecting motor circuits, lighting circuits, electric machinery, transformers and other installations. It can also be used in combination with other high-voltage safety devices such as fuses, relays and surge arrestors.

The working principle of the 1Z25UM circuit breaker involves the detection of fault currents and the disconnection of the load when a fault current is detected. When a fault current passes through the circuit breaker, it triggers the release of an electric arc across the breaker points. This arc quenches, or shortens, the fault current and causes the circuit to be disconnected. This disconnection prevents any further damage or harm from occurring due to the fault currents.

The 1Z25UM circuit breaker also incorporates an over voltage protection system. When an over voltage is detected, the breaker will cause a relay to trip and shut off the power. This mechanism protects the installation from damage due to excessive voltage. The 1Z25UM also has a circuit indication system, so that it can indicate when a circuit is in use, or has failed.

The 1Z25UM circuit breaker is designed for medium and large installations that require reliable and efficient protection from overvoltage and fault currents. It is suitable for a variety of applications, including motor circuits, lighting circuits, electric machinery, transformers and other installations. It is also capable of simultaneous disconnection of the supply circuit in the event of a fault, which makes it suitable for applications where the supply needs to be disconnected quickly to avoid damage or harm.

The working principle of the 1Z25UM circuit breaker involves the detection of fault currents and the disconnection of the load when a fault current is detected. It also incorporates an over voltage protection system, as well as a circuit indication system, so that it can indicate when a circuit is in use or has failed. Together, these features make the 1Z25UM circuit breaker a reliable and efficient solution for medium and large installations.
