Circuit Breakers

CR15-52-3.00A-R07CV-V Application Field and Working Principle

Circuit breakers are common electrical safety devices that protect electrical circuits from damage caused by overloading or shorting of the circuit. They are used in homes, offices, factories, and other places where electricity is essential to operate machinery or electronic equipment. The CR15-52-3.00A-R07CV-V circuit breaker is specifically designed for medium voltage applications and is a three-phase circuit breaker with a rating of 3.00A.

Objective and Benefits

The purpose of the CR15-52-3.00A-R07CV-V circuit breaker is to protect electrical circuits from being overloaded or shorted out. The three-phase breaker provides a higher level of protection than regular single-phase breakers by providing more efficient disconnection of the circuit and more effective control of the circuit current. In addition, the three-phase breaker can prevent equipment from being damaged by power surges, voltage fluctuations, and short-circuits.

Design and Features

The CR15-52-3.00A-R07CV-V circuit breaker is designed with a variety of features to provide superior protection for medium voltage applications. It has a high dielectric strength of 15 kV and a low rated current of 3.00A. The circuit breaker also includes a spring-loaded latch mechanism, which prevents the breaker from unintentionally tripping, as well as a manual reset button to restore the breaker and reset the circuit after a fault. Furthermore, the breaker features a superior current limiting capability to reduce arcing faults and other incidents of over-current.

Working Principle

The CR15-52-3.00A-R07CV-V circuit breaker relies on a thermal-magnetic mechanism to detect when an over-current is present in the circuit. When a current higher than the rated value is detected, the circuit breaker trips, cutting off the power to the circuit and preventing further damage. The thermal-magnetic mechanism uses both heat and magnetic forces to detect and trip circuit breakers. The thermal element is located in the circuit breaker and is made of a bimetallic strip which bends when exposed to heat and changes the position of a triggering arm. The magnetic element uses magnetic flux generated by the over-current to create a magnet which pulls the triggering arm, and thereby trips the circuit. Aside from the thermal-magnetic mechanism, the CR15-52-3.00A-R07CV-V circuit breaker also includes an overload protection feature. This feature prevents the circuit breaker from tripping prematurely due to an overload. The overload protection is activated when the current in the circuit exceeds a predetermined limit and trips the circuit breaker, cutting power to the circuit and preventing further damage.

Applications

The CR15-52-3.00A-R07CV-V circuit breaker is designed for use in medium voltage applications. It is often used in industrial and commercial settings, such as manufacturing plants, warehouses, power plants, and other places where medium voltage power is used. The breaker is designed to protect circuits from damage caused by over-current, short-circuits, and power surges.In conclusion, the CR15-52-3.00A-R07CV-V circuit breaker is an essential part of any medium voltage system. It provides reliable protection against over-currents, short-circuits, and power surges, and helps prevent equipment damage and downtime. Its thermal-magnetic mechanism, overload protection feature, and other features make it an ideal circuit breaker for medium voltage applications.
