A bad capacitor can cause a breaker to trip. When a capacitor fails, it can disrupt the flow of power to the machine, causing it not to receive the necessary amount of power to operate. This can result in the breaker tripping. Although it's not a major issue in the short term, neglecting this problem can lead to more significant complications over time.
And it depends on the type of capacitor, but factors that can cause open failures include vibration and shock during mounting on the board and transportation, as well as placement of the device on the board. When a capacitor fails a short circuit (Figure 3), DC current flows through the capacitor and the shorted capacitor behaves like a resistor.
A bad capacitor in a device can cause the breaker to trip because the device may not receive enough power to operate due to the issue with the capacitor. There are various types of capacitors in an appliance or device that can get worse and cause a breaker to trip.
For installations where DC supply is not available or where it is uneconomical to provide battery / battery charger for DC supply or where the stations are unattended and battery maintenance cannot be guaranteed, a circuit using capacitor banks is employed to provide tripping energy to the breaker trip coil.
This characteristic is assumed to be due to the deterioration of the dielectric oxide layer at high temperatures, which reduces the insulation of the capacitor, and applying a DC voltage to a capacitor in this state causes the leakage current to increase. How to do, what to do?
The pressure-relief vent *9 of an aluminum electrolytic capacitor used for smoothing the power circuit was ruptured and a capacitor started smoking. When the internal pressure of the capacitor rises, the pressure valve opens and electrolyte (gas) is released.

What Causes Circuit Breakers To Trip?
Circuit breakers are protection devices for electrical circuits. When too much current passes, the breaker trips, stopping the flow of electricity and preventing damage. This can be caused by faulty wiring, too many appliances on one circuit, or a ground fault. Overloading can cause tripping. This happens when too many devices are connected to a single circuit. Heat …
