Working Principle

The 219-3-4540-4 circuit breaker works on the principle of thermal overload protection. The device contains an electrically operated thermal element, which responds to the current flowing through the circuit. When the current exceeds the limit set by the operating pressure, the thermal element triggers the circuit breaker, causing it to trip and open the circuit. This prevents the excess current from flowing and damaging the appliance or the circuit.

The circuit breaker is designed to automatically reset when the underlying fault has been cleared. This means that the device can be used to provide protection over a long period of time, without the need for manual resetting. This makes it a reliable and effective choice for industrial applications.

Conclusion

The 219-3-4540-4 circuit breaker is an ideal choice for a variety of high current applications. It offers protection against short circuits, overloads, under voltages, and phase unbalances, and is capable of handling up to 400 Amps of current. Its adjustable operating pressure allows for more precise control of the circuit, and the spring-loaded mechanism ensures reliable resetting. The 219-3-4540-4 circuit breaker is a reliable and effective choice for many industrial applications.
