Circuit breakers, also known as mcb’s, are important safety features in many electrical systems. The two-pole model, 219-2-1REC5-66-7-9M-70-AH, is a common device used for a variety of purposes in both residential and commercial settings. It provides effective overcurrent protection, while also helping to reduce the amount of energy wasted through accidental powering of circuits that are not in use. Understanding the application field and working principle of the device is important for proper installation and operation.

The 219-2-1REC5-66-7-9M-70-AH circuit breaker is designed to be used in low-voltage and residential applications. It can be used both indoors and outdoors, including in wet or dusty environments. It is commonly found in circuits with a maximum operating current of 7.9A and a maximum voltage of 230V. The device has been tested to the relevant standards and is approved for use in most environments. As with all circuit breakers, it is important that it is installed and operated correctly. It should be mounted securely, and all connections should be kept tight.

The devices basic working principle is not particularly complicated. The 219-2-1REC5-66-7-9M-70-AH is an electro-mechanical device, designed to detect and interrupt abnormal currents in an electrical circuit. This is achieved by having two conductive plates separated by an insulating material. When the current passing through the plates exceeds a pre-determined level, the device will trip, opening the circuit and ceasing the flow of current. The unit has a number of adjustable parameters, such as the trip current, which allow it to be configured for a particular application.

The primary purpose of the 219-2-1REC5-66-7-9M-70-AH circuit breaker is to provide a safe and effective means of managing currents in a circuit. It is important that the device is correctly sized for the application, as incorrect sizing can result in an insufficient current cutoff, or the circuit breaker tripping unnecessarily. The device has a number of features which allow it to deliver reliable protection over time. It is designed to be tamper-proof with a number of safety features, and the individual parts are housed inside a sealed plastic case to provide additional protection.

Other features of the device include protection against leakage, as well as other safety measures such as over-temperature protection. The unit is also provided with two auxiliary contacts which can be used for a variety of purposes, such as remotely controlling the circuit breaker. This allows for easy access and maintenance, as well as providing a way to monitor the performance of the circuit breaker.

In summary, the 219-2-1REC5-66-7-9M-70-AH circuit breaker is a versatile device that is suitable for a variety of applications. Its robust construction and adjustable parameters allow it to provide reliable protection in residential and low-voltage applications. It is important to understand the application field and working principle of the device in order to ensure safe and efficient operation.
