Introduction

Circuit breakers are important safety devices that protect your home, office, or factory against electrical malfunction, overloads and excess currents. The CB255-15 is a type of Circuit Breaker which is designed for medium-voltage applications. It is designed for use in both indoor and outdoor environments with a working voltage of 3.3kV. This Circuit Breaker has a high performance and long life.

Application Field

The CB255-15 Circuit Breaker is primarily used in medium-voltage applications such as factories, schools, hospitals, public buildings, and other installations such as HVAC systems. It is designed for use in both indoor and outdoor environments and is constructed using an epoxy-filled aluminum body with rubber seals. This Circuit Breaker is also suitable for applications that require water and dust protection, such as in ships and marine applications.The CB255-15 Circuit Breaker is also suitable for use in applications that require protecting protective cables against short-circuit damage. It has a higher interrupting capacity than a regular breaker and is capable of interrupting currents up to 20KA. This provides extra protection against damaging short-circuits.

Working Principle

The CB255-15 Circuit Breaker is a thermal-magnetic circuit breaker, which means it is a combination of a thermal overload protector and a magnetic short-circuit tripping mechanism. The thermal overload protector works by sensing increases in electrical temperature within the breaker during overloads. As it starts to detect an overload, the thermal overload protector will trip the breaker and disconnect power from the circuit. The magnetic short-circuit tripping mechanism works by sensing increases in current flow and disconnecting the circuit when a predetermined level is reached. This helps protect cables from short-circuit damage. When the breaker trips, it will remain in the locked-out position until power is restored and the circuit is manually reset.

Conclusion

The CB255-15 Circuit Breaker is an important electronic protection device that is suitable for medium-voltage applications and both indoor and outdoor environments. It is a combination of a thermal overload protector and a magnetic short-circuit tripping mechanism, which provides greater protection against overloads and short-circuits. The high interrupting capacity of this breaker provides additional protection for cables and wires against damaging short circuits.
