A circuit breaker is a device that helps to protect against electrical failure by providing an electrical power system with an automatic switching function. PR21-62-5.00A-38587-4-V is a type of circuit breaker used in applications where tight accuracy and high precision are critical. It automatically detects any excessive current or voltage levels and then responds by connecting or disconnecting the affected circuit.

Working principles

PR21-62-5.00A-38587-4-V circuit breaker works on the principle of magnetic force. The unit contains two sets of magnets: one set is connected to the trip bar, and the other set is attached to the contactor which is located behind the door. When an excessive current or voltage level is detected, the trip bar moves and applies a force to the second set of magnets, which causes the contactor to move and disconnect the circuit. At the same time the contactor closes, a thermal circuit breaker is opened, allowing any excess current or voltage to safely dissipate.

Applications

PR21-62-5.00A-38587-4-V circuit breaker can be used in all types of electrical systems, including industrial, commercial and residential applications. It is typically used in applications that require precision timing and stability, such as:

• Power quality monitoring for commercial and industrial applications
• Circuits with high ambient temperatures
• Control circuits in high-speed data networks and telecommunication systems
• Circuits powered by single or multiple phase power sources
• Medical and laboratory equipment
• Circuit control applications with multiple current circuits

The PR21-62-5.00A-38587-4-V circuit breaker can also be used in applications where it is necessary to monitor and control a high amount of current and/or voltage in a single circuit, such as in the following:

• Large power generators
• High-power switching and inverters
• Switchgear systems and switchyards
• Industrial motors and controllers
• High voltage direct current (HDVC) systems
• DC power supplies
• Large scale electrical transformers

PR21-62-5.00A-38587-4-V circuit breaker helps to ensure that the power supply to all critical systems is reliable and safe. It is also easy to install, maintain and configure, making it an ideal choice for any application that requires a very small and precision circuit breaker for controlling and monitoring power.
