CPP11-52-4.00A-OB-V

Circuit Breakers

Circuit breakers are crucial components of the electrical system. They have been developed to provide safety and protection to circuits, homes, businesses and other important facilities. While most circuit breakers trip frequently throughout their lifetime, they are often overlooked until their use is needed. The CPB11-52-4.00A-OB-V is one such circuit breaker, designed with a specific application field and working principle.

Application Field

The CPB11-52-4.00A-OB-V is used for the overload and short circuit protection of small low voltage motors, AC household appliances, small power tools and digital devices. The circuit breaker is suitable for infrequent operations and is designed for the momentary switching of loads up to a rated current of 4.00A. It is suitable for the mounting in enclosures with a degree of protection four (IP55) in accordance with IEC 60529.

Working Principle

The CPB11-52-4.00A-OB-V operates based on a thermal-magnetic principle. This type of circuit breaker ensures protection against both overload and short circuit currents, without interfering with the normal operation of the system. The thermal element reacts to the buildup of current over time, while the magnetic element reacts almost instantaneously to the inrush of current when machines and equipment are started up. As the current passes through the circuit breaker, it generates heat, which is monitored and regulated by the thermal trip unit.

Trip Settings

The CPB11-52-4.00A-OB-V can be adjusted to suit the current requirement of the installation. It is designed with adjustable magnetic and thermal trip units which can be adjusted according to the current limit of the system. The circuit breaker can be adjusted manually with a simple turn of the knob, or remotely by means of an external control.

Operation

The CPB11-52-4.00A-OB-V has two different operating modes: Mode 1 is the manual reset, requiring users to manually reset the circuit breaker after it trips, while Mode 2 is the automatic reset. In this mode, when the circuit breaker trips due to either an overload or a short circuit, it will reset itself automatically after the cause is eliminated. Depending on the installation, the user can choose between the two modes, making the circuit breaker apt for any type of system.

Safety

The CPB11-52-4.00A-OB-V is designed for safety in mind. It is certified by the UL and CCC, ensuring that the highest quality and safety standards are observed. Its IP55 rating further adds to the circuit breaker\'s durability and performance, allowing it to withstand harsh environmental conditions. Ultimately, it ensures that the system is protected from potential dangers and that the users remain secure.

Conclusion

The CPB11-52-4.00A-OB-V circuit breaker is a versatile and reliable safety device. With its adjustable trip settings and two operating modes, it is suitable for any application, from residential to commercial and industrial. Its protection against overloads and short circuits is perfect for small-scale installations, and its high IP rating adds to its durability. Therefore, the CPB11-52-4.00A-OB-V is a great choice for the protection of circuits and loads.
