Circuit Breakers are a form of electrical switch, which are designed to protect the electrical system from damage due to over-currents, short-circuits or other excessive electrical stresses. The IDGN1-33669-1 is a multifunctional circuit breaker with a range of application fields, which is commonly used in private homes and commercial installations.

The IDGN1-33669-1 is a UL489B listed branch circuit breakers. It is suitable for protection of lighting circuits and motors in industry, commerce and residential use, in accordance with the local codes and regulations. It features both short-circuit protection and overload protection, offering reliable protection for lighting and motors against excessive currents.

Working Principle

The IDGN1-33669-1 is composed of a thermomagnetic element, a molded case and sensitive actuators. When the current through the circuit exceeds the specified threshold, the thermomagnetic element activates and trips the circuit breaker. This activates the actuators, which then manually reset or trip the breaker.

The thermomagnetic element has two key components, namely the bimetallic strip and a magnetically operated armature. When the current through the circuit exceeds the specified threshold, thermal energy will be generated in the bimetallic strip due to the Joule effect. This increases the temperature of the strip and will cause it to bend. This bending will then actuate the armature, thus engaging the circuit breaker and trip the power supply.

The IDGN1-33669-1 is designed to be reset manually, meaning that after the overload has been removed, the actuators must be manually reset in order to turn the circuit breaker back on. To reset the breaker, the actuators must be fully in the off position by pressing the actuator handle with the tip of your finger until it stays in place.

Conclusion

The IDGN1-33669-1 is a versatile and reliable branch circuit breaker, designed to offer protection against short-circuits or overloads. Its thermomagnetic element is designed to activate under excessive current, therefore tripping the supply, which is then manually reset after the overload has been removed. With its range of application fields, the IDGN1-33669-1 is a perfect choice for private homes and commercial installations.
