Introduction

Circuit breakers are widely used in electricity systems and are quite common in everyday life. IEGHF662-35049-50-V is a type of circuit breaker, and its application field and working principle are important topics for one to understand in order to safely use this electrical appliance.

Application Field

IEGHF662-35049-50-V is designed to be used on low voltage networks (<1000 V). It is a dual-pole circuit breaker with a rated current of 50 Amps and a rated ultimate short circuit capacity (Icu) of 10 kA (10 thousand amps). The circuit breaker can be used in residential, commercial, or industrial applications.

IEGHF662-35049-50-V is particularly suitable for use in low voltage networks that require high overload or short circuit protection.

This circuit breaker is also compatible with numerous protection devices and accessories, such as current transformers, residual current devices, and more. This type of circuit breaker is designed to be highly reliable and efficient, with a rating that allows for a much higher interruption capacity than other circuit breakers. Furthermore, due to its design, the circuit breaker is more flexible in terms of installation and wiring than other types of circuit breakers.

Working Principle

The IEGHF662-35049-50-V is essentially an automatic electrical switch which is designed to open or close an electric circuit in response to an overload or short circuit. The operation of the circuit breaker is based on the damping and mechanical tripping principle.When an overload or short circuit happens, the circuit breaker senses the current increase due to the fault and, due to its inclusion of a current-limiting resistor, the flow of current passing through the circuit breaker is limited. This resistor limits the energy delivered to the circuit breaker and thereby reduces the stress of the components and ensures that the breaker performs optimally in the case of a fault occurring.The damping principle is then applied to ensure the fast and correct tripping of the contacts. The contact arm carrying the moving contact is held in equilibrium between two tension springs. When the electrical current increases, the breaker arm moves and compresses one of the tension springs, resulting in a differential force generated by the two springs. The extra force causes the contact arm to rotate and thus open the contacts. Once opened, the circuit breaker must be manually reset before it can be used again. The resetting is done by pushing the reset button; when this button is pushed, two springs are pressure set, providing a counter-acting force which resets the contact arm back into its original position. Ultimately, this ensures the safe operation of the circuit breaker in case of an overload or short circuit.

Conclusion

In conclusion, this article has presented the application field and working principle of the IEGHF662-35049-50-V circuit breaker. This circuit breaker is particularly suitable for low voltage networks due to its high-rated interruption capacity and flexible installation and wiring capabilities. Its working principle combines the damping and mechanical tripping principles to ensure active and reliable protection in the case of a fault.
