A Circuit Breaker is a type of mechanical switchgear that automatically disconnects the circuit to protect the elements of a power system from the damaging effects of overcurrent. In simple words, a circuit breaker disconnects a circuit under faulty conditions by interrupting the overcurrent flow ...
A circuit breaker is a hardware device that activates when the current drawn from the power exceeds a set level. Its purpose is to prevent damage to electrically powered equipment during a power surge or electrical malfunction. If the breaker is tripped, a switch is turned off to prevent any...
A circuit breaker is a type of overcurrent protective device, or OCPD. Current is another name for amperage, or the rate of flow of electrons in an electrical circuit. (Voltage is the amount of pressure in a circuit). All the wiring and devices on a circuit are rated for a maximum le...
The lever, also known as a switch, is connected to the trip unit. The switch allows the circuit breaker to get off or on. When there is a short circuit or overloaded, the circuit trips at that point and the lever gets positioned in the middle and identifies which components need troubles...
A residual current circuit breaker (RCCB) is an electrical safety device that detects and interrupts an electrical circuit when there is a leakage current to the ground. It protects people and equipment from electric shocks, fires, and other hazards caus

1. Circuit Breaker Function.Thefunctionof an electrical circuit breaker is to “break” (that is, to discontinue) a circuit of electricity. It does this automatically when it detects: *an electrical overload-- The power demand on one of the circuits is beyond its capacity, usually because yo...
hold invaluable data, electronic devices are integral to every aspect of our lives today. Understanding how to protect these valuable assets is more important than ever. One of the most common but often overlooked threats to our electronics is a power surge. But what is a power surge exactly?
