R21-1REF..S00316911

A circuit breaker is a device designed to protect an electrical circuit from damage caused by an overload or short circuit. The R21-1REF..S00316911 is a type of circuit breaker designed for use in low voltage and DC applications. It is typically used in industrial or commercial applications.

The R21-1REF..S00316911 circuit breaker is equipped with a thermal overload protector, a thermal magnetic trip unit, and a mechanical indicator. The thermal overload protector monitors the circuit current, and if it exceeds a predetermined level it will trip and shut off the electricity supply. The thermal magnetic trip unit is triggered by an overload or short circuit, and it also shuts off the electricity. The mechanical indicator shows the state of the circuit breaker: if it is on or off.

The R21-1REF..S00316911 circuit breaker has a number of benefits when compared to other types of circuit breakers. For example, it is designed for use in low voltage and DC applications, so it is able to protect electrical circuits from more powerful surges than other circuit breakers. It also has a number of features that make it easier to use, such as the thermal trip indicator and the mechanical indicator.

The R21-1REF..S00316911 circuit breaker is commonly used in industrial and commercial applications to protect electrical circuits from damage due to power surges, overloads, and short circuits. It is also often used in solar panel installations, as it is capable of protecting high-efficiency solar cells from the power surges that can occur during sudden weather changes.

In summary, the R21-1REF..S00316911 circuit breaker is a type of low voltage and DC circuit breaker designed for use in industrial and commercial applications. It is equipped with a number of features that make it easier to use, such as a thermal overload protector, a thermal magnetic trip unit, and a mechanical indicator. The circuit breaker is capable of protecting electrical circuits from powerful surges, overloads, and short circuits, and is commonly used in solar installations.
