What’s break capacity?

Breaking capacity is the maximum number of amperes or volts that a circuit breaker can break. A switch should have a high enough breaking capacity to interrupt the maximum possible current and voltage in a system to prevent damage to electronics or a building. Fuses and circuit breakers work on the same principle, but a circuit breaker is designed to trip a switch that cuts off the electrical current. The breaking capacity of a switch is less than the value of its making capacity. Each piece of equipment is given a rating based on the maximum current and maximum voltage it can interrupt.

Breaking capacity, sometimes referred to as breaking capacity, is the maximum number of amperes or volts that a circuit breaker can break. Each device designed to interrupt the electric current can have more than one breaking capacity because the voltage to which it is exposed affects the number of amperes it can interrupt. It is important to use a switch that has a high enough breaking capacity to interrupt the maximum possible current and voltage in a system because an uncontrolled surge of electrical energy can damage electronics or a building.

When a fuse, which is a simple device used to protect an electrical circuit, reaches its breaking capacity, it blows. Under normal circumstances, electric current flows freely through a fuse, but if the current or voltage becomes too high, the fuse heats up until the wire inside disintegrates. Once a fuse has reached its breaking capacity, it will no longer function and will need to be replaced.

A circuit breaker works on the same principle as a fuse, but is designed to trip a switch that cuts off the electrical current once the device’s breaking capacity is reached. Resetting the circuit after this has happened is simply a matter of flipping the switch back the other way. While most circuit breakers are designed to protect electronics from damage, some are also designed to protect people from electric shock.

The breaking capacity of a switch is less than the value of its making capacity, which is the maximum voltage or current that the machine can carry. As voltage and current increase, it becomes more difficult for a switch to interrupt the flow of electricity, so the capacity is reached before the creation capacity. At high levels, electric current is capable of arcing, which allows energy to bridge the gap between two conductors that are not in physical contact with each other. Current could, potentially, continue to flow through an open circuit, even though the physical line has been broken.

A fuse or circuit breaker is assigned a breaking capacity value which indicates the maximum level that the apparatus is capable of breaking. Each piece of equipment is given a rating based on the maximum current and maximum voltage it can interrupt. For safety reasons, a switch should be rated high enough to handle the maximum possible voltage and current in a given system. A surge of electricity can destroy electronics or cause fires within a building’s electrical system.
