Circuit breakers are widely used in local power grids to protect electrical appliances from overloads or short circuits. One of the widely used circuit breakers is the CB255-10 circuit breaker. Let us take a closer look at its application field and working principle.

The CB255-10 is designed for single-phase AC low voltage power distribution system. It can withstand a maximum level of 10A when placed in 220V AC power systems. It can protect circuit systems from overloads, short circuits and other abnormal conditions. The CB255-10 can be used as a main switch in household and industrial power supply systems, or an auxiliary switch that protects electrical appliances from overuse.

The CB255-10 circuit breaker is made up of three main components: a contact, an arc suppressing device, and a circuit breaker mechanism. The contact is the part that directly connects the circuit. It is made up of a pair of contacts which are connected when the breaker is closed. When the breaker is opened, the contacts separate and the circuit is “broken”. The arc suppression device helps to extinguish the arc that is produced when the contacts are separated. The breaker mechanism is responsible for opening and closing the contacts. It is usually a spring-powered mechanism that can quickly open and close the contacts.

When the circuit breaker is opened and closed, the contact is released or pressed against a stationary contact. For the CB255-10, this is done by an arc suppression device. The arc suppression device uses an arc extinguisher to quickly stop the current flowing between the contacts when the switch is opened. When the switch is closed, the gap between the contacts is reduced and the contact pressure is increased. This ensures that there is a direct and reliable connection between the contacts.

The CB255-10 circuit breaker is also equipped with a current limiting device. This device is responsible for regulating the current that flows through the circuit by limiting it to the rated current level. When the current exceeds the rated value, the current limiting device will open and the circuit breaker will shut off to protect the circuit.

The CB255-10 circuit breaker is a reliable and effective device that can be used in a wide variety of applications. It is designed to be durable and reliable, and has a long lifespan. Its current limiting device ensures that the circuit is protected from overloads and short circuits. The arc suppressing device helps to quickly extinguish the arc between the contacts for safe and reliable operation.
