Circuit Breakers
Circuit breakers are safety devices used in electrical distribution systems for protection against overload and short circuit conditions. When an overload or short circuit occurs, a circuit breaker trips its contacts open to isolate the electrical circuit and protect it from damage. The specific type of circuit breaker used in an electrical system will depend on the system\'s voltage, load current, and environmental conditions.
219-1-4427-8 Application Field and Working Principle
The 219-1-4427-8 circuit breaker is a heavy-duty two-pole breaker designed for use in industrial and commercial applications. This type of circuit breaker is typically used in high-voltage, high-amperage, three-phase systems where protection from high overcurrents is necessary. It can operate to provide protection against short circuits and overloads, and can be manually reset to restore service.
This circuit breaker is able to provide overcurrent protection for a wide range of loads, from large motors and transformers to smaller devices such as computers and data communication systems. With an interrupting rating of 65,000 Amps, the breaker is suitable for most application requirements.
The working principle of the circuit breaker is based on an electromagnetically-operated mechanism. The breaker is equipped with a thermal-magnetic trip unit that senses overloads and short circuit conditions and trips the contacts. Inside the trip unit is a thermal trip coil paired with a magnetic trip coil. The thermal trip coil senses overloads and allows the breaker to trip and open the circuit as soon as the overload current reaches the trip level. The magnetic coil senses and trips the circuit in the event of a high-level, short-circuit current. Both coils are connected to an electromagnetically-operated operating mechanism that opens the circuit breaker contacts.
When an overload or short circuit is detected, the thermal trip coil is activated, and a current passes through the electromagnetic device. The device then causes the contacts of the circuit breaker to open, isolating the circuit and protecting it from further damage. In order to reset the breaker, the circuit must first be de-energized and then the breaker must be manually reset.
The 219-1-4427-8 circuit breaker provides an excellent combination of protection and reliability. Its heavy-duty construction ensures a greater degree of current-handling capability and its compact size makes it suitable for a variety of applications. Its trip unit offers complete and reliable overcurrent protection, and its easy resetting makes the breaker a great choice for industrial and commercial applications.
