R21-1REF..S00270563

Circuit breakers are electrical devices that are used to break or interrup a circuit so as to protect it from any potential damages, in the event of sudden or large electrical surges or a fault. The R21-1REF..S00270563 is a circuit breaker designed to prevent overvoltage and short current faults, in medium voltage systems. It employs a unique combination of high breaking capability, high contacting speed and specialized insulation that offer outstanding electrical protection.

Application Field

In medium voltage applications, the R21-1REF..S00270563 circuit breaker is the ideal solution for ensuring safe and reliable operation. It can be used with medium-voltage networks and industrial power systems. It ensures adjustable overload protection and short circuit protection, as specified in the relevant national standards. It is capable of protection against over voltages, short circuits, overloads, and all types of electrical faults.

Working Principle

When there is an overload, or a short circuit, the magnetically coupled operating mechanism of the circuit breaker isolates an uninvolved circuit from the main circuit. This allows the fault to be isolated from the rest of the system. During the operation of the circuit breaker, an arc is formed between the stationary and moving contacts. This arc is quickly extinguished and a loud sound is heard when the breaker interrupts the current. Once the arc is extinguished, the current is no longer able to flow, interrupting the current. The circuit breaker then returns to its normal operating position.

The R21-1REF..S00270563 circuit breaker has many features that make it the ideal solution for medium voltage applications. It has a very high breaking capacity, a high travelling speed and a specialized insulation that offer superior electrical protection.

Overall, the R21-1REF..S00270563 circuit breaker is a highly reliable and efficient device designed to protect medium voltage systems from overvoltage and short current faults. It offers superior protection from electrical failure and ensures safe and reliable operation of medium-voltage networks and industrial power systems. It is the perfect choice for medium voltage applications.
