Circuit breakers are specialized switching devices with the primary function of protecting an electrical circuit from damage caused by overload or short circuit. This is accomplished by interrupting the electrical current when the predetermined trip settings are exceeded. The CELHK11-71165-8-V is specifically designed to provide a high breaking capacity up to 5kA at 415V. In addition, the trip-free feature means that a fuse cannot be added during the ON condition to restart the system.

Overview of CELHK11-71165-8-V

The CELHK11-71165-8-V is a type of circuit breaker that is specifically designed to provide short circuit and overload protection in electrical circuits. It is designed to be an economical and reliable solution to protect vulnerable equipment from the damaging effects of high power electrical faults. It is manufactured with high quality components for long-term reliability and performance. This circuit breaker is available in several sizes ranging from 6A to 80A with a voltage rating of up to 415V. It is also available in different trip characteristics such as Type B, C, D, K, and T.

Application Fields

The CELHK11-71165-8-V circuit breaker is suitable for many types of industrial and commercial applications. It is commonly used as upstream protection for smaller control circuits. It is also commonly used in residential and commercial buildings to provide protection for air conditioning systems, lighting, office equipment, elevators, and fire alarm systems. It is also suitable for machine tool control panels, electric motors, heating and air conditioning systems, heating furnaces, pumps, and utility services. In addition, it can be used as a main branch circuit breaker on single phase or three phase systems in small commercial and residential applications.

Working Principle

The CELHK11-71165-8-V circuit breaker is a thermal-magnetic type breaker. It contains both a thermal trip unit and a magnetic trip unit. The thermal trip unit is a self-contained electric switch that responds to an increase in temperature caused by an overload or a short circuit. The magnetic trip unit is located inside the main breaker body and it responds to a rapid increase in current flow in the circuit. When the current exceeds the manufacturer’s trip settings, the electromagnetic field created by the current causes the magnetic trip unit to trip the breaker. The trip mechanism is designed to provide fast and accurate interruption of the electrical circuit in the event of an overload or short circuit.

Conclusion

The CELHK11-71165-8-V circuit breaker is designed to provide reliable protection against short circuit and/or overload conditions in electrical circuits. It is suitable for many types of industrial and commercial applications and is available in several sizes ranging from 6A to 80A with a voltage rating of up to 415V. The breaker contains both a thermal trip unit and a magnetic trip unit, which work in tandem to interrupt current flow should the trip settings be exceeded. It is a reliable, economical, and effective solution for circuit protection and peace of mind.
