Circuit Breakers are devices that are used to protect electric circuits from being overloaded and possibly burned out. The 219-4-6388-084 is a circuit breaker with a specific application field and working principle.

The 219-4-6388-084 circuit breaker is suitable for use in installations with a nominal voltage of 690 volts. It can also be used in installations where the maximum voltage does not exceed 601.5 volts. This circuit breaker also has the ability to be used in three-phase power systems with a maximum breaking capacity of 10,000 amperes. This makes the 219-4-6388-084 circuit breaker perfect for large industrial and commercial applications.

The working principle of the 219-4-6388-084 circuit breaker relies on a thermal-magnetic tripping system. When the breaker is first turned on, the current flowing through it is monitored closely. If the current reaches a predetermined value, the control unit within the breaker will trip the circuit breaker. The current measured is compared to a trip setting which is adjustable according to the specific application. The trip setting helps to protect the circuit breaker from being overloaded which can cause damage to the circuit, and ultimately, the installation.

Once the trip setting has been reached the tripping system works in two stages. First, the system will detect and quantify the amount of heat that has been created by the excessive current, and then trigger a relay that will switch the circuit breaker off. This prevents any further damage or harm occurring from the excessive current.

The second stage of the system is the magnetic element, which is set at the same trip setting as the thermal element. The magnetic element will monitor the current flowing through the circuit until the amount of current falls below the trip setting. Once the current has dropped below the trip setting, the magnetic element will switch on the breaker again, allowing the current to flow.

The 219-4-6388-084 circuit breaker is perfect for use in industrial and commercial applications due to its ability to monitor current levels and switch on and off accordingly. Its thermal-magnetic tripping system also provides extra safety to protect the circuit and the installation.
