R21-4-10.0A-30067-1-V

Circuit breakers are electrical fire safety devices that are used to detect and protect circuits from overloading. When a circuit breaker detects an overload or over-voltage, the breaker trips, effectively cutting power to the load.

R21-4-10.0A-30067-1-V application field and working principle:

The R21-4-10.0A-30067-1-V is a type of circuit breaker, designed for electronic protection applications in households and industrial systems. Generally, it is designed to have a ratings of 10.0A, 400V and a voltage range of 80…240V. The action of the R21-4-10.0A-30067-1-V circuit breaker is based on self-resetting sensors which sense temperature and current overloads, short circuits, and ground fault conditions. When an overload occurs, the sensors react quickly by opening the contacts and disconnecting the circuit. Additionally, the R21-4-10.0A-30067-1-V circuit breaker is equipped with a manual reset and an audible warning to alert users that the circuit has been disconnected.

The R21-4-10.0A-30067-1-V circuit breaker is predominantly used in residential and light commercial applications, such as audio/video systems, home automation systems, alarm systems, computer networks and any other system where protection against current overloads, short circuits and ground faults is needed. Because of its design, the R21-4-10.0A-30067-1-V does not require an external power source and is also extremely reliable and capable of withstanding high levels of shock and vibration.

Conclusion:

The R21-4-10.0A-30067-1-V circuit breaker is an effective and reliable type of circuit breaker designed for electronic protection applications in residential, commercial and light industrial settings. This circuit breaker is designed to detect and protect circuits from overloading, short-circuiting, and ground fault conditions. It is easy to install, and provides reliable, long-term performance without requiring an external power source.
