Circuit breakers are essential components of an electrical system which are designed to detect abnormal currents,short circuits, overvoltages and other issues that may arise during system operation and take necessary measures to protect the components connected to it.

R21-1-25.0A-34020-7-V is a type of circuit breaker, which has vacuum virtual arc extinguishing device built in. The virtual arc extinguishing device provides a rapid response while keeping the voltage discharge rate down to a lower level. This particular circuit breaker has a rated current of 25A and a rated voltage of 380V. It is mainly used in industries and commercial applications as a protective device.

The operating principle of the R21-1-25.0A-34020-7-V circuit breaker is relatively simple. When a short circuit or an overload is detected, the device will open the circuit and interrupt the current flow to the components connected to it. This helps prevent electrical fires and other potentially dangerous scenarios. It is important to note that the circuit breaker has its own internal protective mechanisms which must be reset manually before it can provide protection from such an event again.

There are several advantages to using the R21-1-25.0A-34020-7-V circuit breaker. Since it is equipped with the vacuum virtual arc extinguishing device, it can provide fast response time while keeping the voltage discharge to a minimum. This helps protect the components connected to it from external damage due to overvoltage. Additionally, due to its compact size, the device can be easily installed in tight spaces.

The R21-1-25.0A-34020-7-V circuit breaker is an ideal choice for any industrial or commercial application. It is a reliable device which can provide the necessary protection against abnormal currents, overvoltages, and other issues that may arise during operation. It is also equipped with a vacuum virtual arc extinguishing device which can provide faster response time while keeping the voltage discharge rate to a minimal level.
