CPP11-52-20.0A-OC-V

Circuit Breakers

A circuit breaker is an electrical switch used to protect an electrical circuit from an overload or short circuit. In normal operation, the switch is open, meaning it allows electricity to flow through the circuit. If the circuit becomes overloaded or if a short circuit occurs however, the switch will automatically close, cutting off the electrical flow and protecting the circuit.

CPP11-52-20.0A-OC-V is a type of circuit breaker used in applications that require a high current rating and a reliable, robust design. It is designed for a wide range of industrial, commercial and residential applications. The device has a current rating of up to 20.0A and is suitable for AC 45/75 Vac service.

Applications

CPP11-52-20.0A-OC-V circuit breakers are commonly used in applications where a circuit breaker needs to be installed in a restricted space. They are also used in applications where the current rating is required to be greater than 20A, such as commercial and industrial electrical circuits. The device is also suitable for marine environments due to its robust design. Common applications include motor control centers, switchboards, and solar panel installations.

Working Principle

The CPP11-52-20.0A-OC-V circuit breaker is a thermal-magnetic type device. It consists of two parts; a thermal element and a magnetic element. The thermal element consists of a bimetallic strip which will heat up when the current flowing through the circuit exceeds its rating. Once the bimetallic strip reaches a certain temperature, it will trip, interrupting the circuit. The magnetic element also trips in the event of a short circuit, immediately cutting off the power. The thermal element will reset when the temperature reduces, while the magnetic element will only reset when the short-circuit condition is removed.

Conclusion

CPP11-52-20.0A-OC-V circuit breakers are a reliable and robust device used in a variety of applications that require a high current rating. The device works on a thermal-magnetic principle, with both a thermal and magnetic element tripping the circuit in overload or short circuit condition. This makes the device suitable for harsh environments, such as marine applications.
