Circuit breakers are important components in electrical systems that monitor and protect the power circuit against potential faults, such as short circuiting, and over-loading. The R21-62F-20.0A-S01IV-V is a circuit breaker manufactured by ABB and is designed for use in industrial and marine applications.

This circuit breaker device is a single pole, thermal-magnetic moulded-case circuit breaker with a case rating of 20.0 Amps. It is rated for a maximum operating voltage of 230 Vac and a rated frequency of 50–60 Hz. This device is intended for regular circuit protection applications in industrial and marine environments and is constructed from a robust plastic material.

The operation of the device involves two internal components, a thermal-magnetic element and a contact. When current flows through the thermal-magnetic element, it will heat up and cause the element to magnetically disconnect the contact, breaking the circuit. The thermal-magnetic element also monitors the amount of current flowing through the circuit and will trip the breaker if an over-current is detected.

The device also has additional features to enhance its power protection capabilities. For example, the circuit breaker is equipped with short-circuit protection, which provides additional protection against short-circuiting and overloads. It also has over-voltage and under-voltage protection, which will trip the breaker if the voltage level is too high or too low.

The circuit breaker is also equipped with a test button, which is used to conduct tests on the device and ensure that it is functioning properly. Additionally, the device has an LED indicator, which indicates the current state of the breaker.

The R21-62F-20.0A-S01IV-V Circuit Breaker is an important component for power-protection applications in industrial and marine environments. This device offers a high level of protection against short-circuiting, over-loads and over-voltages, making it an ideal choice for protecting power circuits.
