4230-T130-K0BU-30A

Circuit breakers are electrical devices designed to protect an electrical circuit from damage by interrupting the current when an overload or short circuit is detected. The 4230-T130-K0BU-30A circuit breaker is a two-pole ground-fault circuit interrupter (GFCI) designed for use in 120/240VAC applications in residential and commercial buildings. It is used to detect and interrupt leakage current in a circuit, protecting personnel from contact with hazardous current. It is commonly used in bathrooms, kitchens, basements, and other areas believed to contain shock hazards due to potential water contact.

The 4230-T130-K0BU-30A features an LCD display that indicates whether it is in a normal state ("ON") or a tripped state ("OFF"). The breakers also feature an adjustable trip time that allows the user to set the amount of time it takes for the breaker to switch off when the current exceeds the preset trip level, typically between .5 and 2 seconds. This feature can be used to reduce nuisance trips caused by momentary surges in current.

The breaker also has a test mode that allows the user to test the responsiveness of the trip mechanism. This mode functions by manually tripping the breaker, generating a test signal, and resetting the breaker. During testing, it is important to ensure that all wiring is in accordance with local codes and that the breaker is properly grounded.

The 4230-T130-K0BU-30A works by monitoring the amount of current flowing through its line and load terminals. When a fault is detected, the breaker trips, interrupting the flow of current and preventing any potential damage that could be caused by current overloads or short-circuiting.

The breaker also features a built-in ground-fault protection that helps protect personnel from electric shock if the protective earth to the load is connected. This feature helps to protect personnel from contact with hazardous current. When a ground-fault is detected, the breaker interrupts the current and can be reset after the fault is cleared.

In summary, the 4230-T130-K0BU-30A circuit breaker is designed for residential and commercial 120/240VAC applications. It is a two-pole ground-fault circuit interrupter (GFCI) designed to detect and interrupt leakage current in a circuit, protecting personnel from contact with hazardous current. The breaker also features an adjustable trip time, test mode, and ground-fault protection.
