R21-1REF..00464473

Introduction

Circuit breakers are designed to protect electrical circuits from damage caused by overloads, short circuits or surges in the voltage. The circuit breaker is an essential part of any electrical system. The R21-1REF..00464473 is an advanced version of circuit breaker which includes advanced features for better protection and better control of the current flowing through the circuit.

Application

The R21-1REF..00464473 is mainly used in domestic, commercial and industrial settings for protection of electrical devices against overloading and short-circuiting. It is also widely used for controlling the flow of current in larger circuits, such as in electric motors, power lines and in power distribution systems. For applications such as these, this circuit breaker is a reliable and cost-efficient device.

Working Principle

The R21-1REF..00464473 works on an inverse time-delay principle. When a fault is detected in the circuit, the breaker trips and shuts off the flow of current between its contacts. This is done by reducing the clearance between the contacts, which causes an increase in the contact resistance, resulting in a decrease in current flow. The inverse time-delay mechanism is activated when the current exceeds a pre-selected threshold, and the system then takes several seconds to shut off the circuit. This is designed to provide maximum protection against excessive current flow.

Conclusion

The R21-1REF..00464473 is a reliable and cost-efficient circuit breaker for use in both domestic and industrial settings. Its advanced features include an inverse time-delay principle that provides maximum protection against overloading and short-circuiting. This circuit breaker is a reliable and cost-efficient device that is designed to protect electrical circuits from damage caused by overloading, short-circuiting and surges in the voltage.
