The PR21-62-3.00A-38587-1-V circuit breaker is a small-sized, light-weight device intended for use in electronic control systems. It is specifically designed to protect circuits from over current and short circuit in a number of important situations. Because of its size, weight, and reliability, it is also suitable for installation in panel boards, switchgear, motor control centers, and other industrial control systems.

The purpose of this device is to protect circuits from overload or current surges. It can act as a component of any over-current protection system. It is not only a protective device, but also can provide an indication of circuit status. An indicator in the circuit breaker gives an indication of the current passing through it and the voltage drop across the contacts. In addition to this, the circuit breaker also has built-in automatic reset and over-voltage protection.

The working principle of the circuit breaker is straightforward. When a current passing through the circuit breaker reaches a predetermined level, the contacts in the device are opened, which breaks the circuit and stops the electrical current. This prevents the device from further damage due to the overload or high voltage. Usually, the current passing through the circuit breaker is monitored by an external device, such as an ammeter, and once the current reaches the predetermined level, an alarm is activated, allowing the user to take appropriate action.

The PR21-62-3.00A-38587-1-V circuit breaker can be used in a variety of applications, including motors, computers, televisions, air conditioners, refrigerators, electric heating systems, and lighting systems. It is particularly suited for use in circuit boards and other electric control systems that are subject to high levels of current or voltage. The device is also commonly used in industrial control systems, where the circuit breaks must be set for the proper protection of the equipment.

In conclusion, the PR21-62-3.00A-38587-1-V circuit breaker is a reliable and lightweight device that is specifically designed for protecting circuits from over-currents and short circuits. Its size, weight and performance make it suitable for many applications, and its built-in features provide indication of circuit status and automatic reset and over-voltage protection. The device is useful in a variety of applications, including motors, computers, televisions, air conditioners, refrigerators, electric heating systems, and lighting systems.
