Circuit breakers are an important component of electrical systems, providing protection against overloads, short circuits and other dangerous conditions. One type, the R21-1REF..00454435, is commonly used in industrial and commercial applications and is known for its reliability and safety. This article will detail the fields of application and the working principles of the R21-1REF..00454435 circuit breaker.

The R21-1REF..00454435 is an advanced, three-pole protection device with a plastic residual current circuit breaker (RCBO) and a short circuit protection differential current monitor (DME). It is designed for the most demanding industrial and commercial applications, where safety and reliability of the system is paramount. It has a rated voltage of 440V AC and is capable of handling currents of up to 32A. It is IP20 rated, which ensures greater protection against dust and other debris.

The R21-1REF..00454435 is designed to protect electrical systems from damage due to overcurrent. When an overload occurs on any of the three poles, the device responds by opening the circuit. This prevents further current from flowing, which stops the system from being damaged by the overload. The device also provides short circuit protection, as it is designed to stop any damaging current caused by short circuits from flowing. This protects the electrical system from damage, as well as helping to reduce the risk of fire caused by short circuits.

The R21-1REF..00454435 is also equipped with a DME, which is an essential component of circuit breakers. The DME is used to detect differences in current which could indicate a fault in the system. When the DME detects a difference, it will open the circuit and prevent any damaging current from flowing. It can also be used to detect differences in phase, which can help to identify any potential issues with appliances or other equipment connected to the system.

The R21-1REF..00454435 is an important part of any industrial and commercial electrical system. Its advanced design and reliable components make it an ideal choice for applications which require maximum protection. The device is also designed to reduce the risk of fire or electrical shock, and its robust protection can help to ensure the safety of personnel and equipment. The R21-1REF..00454435 is a reliable and efficient device which can provide a long lasting solution for many applications.
