Circuit Breakers

Introduction

Circuit breakers are the most important elements of electrical and electronic circuits as they protect electrical wiring by tripping and disconnecting the circuit during a fault condition. The IELHK111-31931-9-V circuit breaker is a compact, low-maintenance device that is a reliable safety device in a wide range of electrical and electronic applications.

IELHK111-31931-9-V Application Field

The IELHK111-31931-9-V circuit breaker is a compact, low-maintenance device ideally suited for protecting domestic households or other enclosed electronics or electrical systems. In household installation the IELHK111-31931-9-V is capable of protecting up to 10 Amps. The device has a touch-safe function which ensures that fingers do not come in contact with the live parts of the circuit when the cover is removed.

Working Principle

The IELHK111-31931-9-V circuit breaker works by automatically opening the circuit and stopping the flow of current if the electrical current running through the circuit exceeds a predetermined level. This is usually caused by several factors such as overload, electrical arc, short-circuits and excessive temperatures.When the trigger conditions have been reached, a bimetallic strip bends then breaks and supplies the electrical power to an external switch. This switch operates a mechanism that slowly turns off the circuit breaker, thus releasing the electrical power from the system and preventing the electrical circuit from further damage.The device also operates on the basis of a thermal overload trip mechanism whereby, due to high current, the resistance created by the bimetallic strip causes heat generation, resulting in the strip working as an overload sensor. This then activates the external switch to open the circuit and reduce the risk of damage to the circuit.

Conclusion

The IELHK111-31931-9-V circuit breaker is a reliable safety device designed to protect domestic households or other enclosed electronics or electrical systems. The device is a compact and low-maintenance product that is designed to protect against overloads, electrical arcs, short-circuits, and excessive temperatures. The device\'s bimetallic strip and external switch work together to detect the trigger conditions and quickly open the circuit to prevent further damage.
