Circuit Breakers

Circuit breakers are electrical devices that interrupt current in an overloaded or short-circuited circuit. They are designed to protect the circuits and equipment from damage due to overloading, short-circuiting, or other faults. Circuit breakers are available in a wide range of sizes and types, and each has specific characteristics and capabilities to provide protection for an electrical circuit.

The R21-4-7.50A-9191-3-V circuit breaker is designed to provide reliable overload and short-circuit protection. It uses an innovative design incorporating a patented arc deflector system, which quenches the arc faster than traditional circuit breakers. This allows the circuit breaker to interrupt higher current levels and provide better protection to the circuit.

Application Field and Working Principle

The R21-4-7.50A-9191-3-V circuit breaker can be used in a variety of industrial, commercial, and residential applications. It can be used to protect circuits from overload or short-circuits, and it can also be used to protect specialized equipment or sensitive electronic devices from surges and transient voltages. The circuit breaker can also be used in motor control systems to provide protection against overcurrent and locked rotor conditions.

The R21-4-7.50A-9191-3-V circuit breaker works in conjunction with a thermal trip element. The element senses the current flowing through the circuit, and when the current reaches a certain threshold, the element activates, triggering the circuit breaker to open and break the circuit. This is done to protect the circuits, connected equipment, and electrical system from damage due to excessive current. This type of circuit breaker also incorporates an arc deflector system, which quickly quenches the arc produced when the breaker opens.

The circuit breaker\'s arc deflector system consists of two plates, each mounted at 45° angles to each other. When the breaker opens, an arc is produced at the contact points. The arc deflectors redirect the arc away from the contact points, allowing the arc to be quickly extinguished, thus protecting the contacts and preventing further damage. The patented arc deflector system allows the R21-4-7.50A-9191-3-V circuit breaker to interrupt much higher current levels than traditional circuit breakers.

The R21-4-7.50A-9191-3-V circuit breaker is an innovative and reliable protection device, providing superior overload and short-circuit protection for residential, commercial, and industrial applications. The patented arc deflector system allows it to quickly and safely interrupt current, protecting connected equipment and the overall electrical system from damage due to excessive current.
