Introduction to 1G3.5UM Circuit Breakers

Circuit breakers are a critical aspect of electrical engineering. They are an important part of electrical systems as they provide a means for isolating and protecting circuits from current overloads. They are used to protect both equipment and personnel from potential damage from an excess of current. The 1G3.5UM is a specific type of circuit breaker that offers specific features and capabilities. In this article, we\'ll look at the application field and working principle of the 1G3.5UM.

Application Field of 1G3.5UM Circuit Breakers

The 1G3.5UM circuit breaker is one of the most common and widely used circuit breakers in the industry. It is a medium voltage circuit breaker that is used in a wide variety of applications. It is commonly used in both commercial and industrial settings.The 1G3.5UM circuit breaker is designed to handle up to a maximum short circuit current of 3.5 kA rms (3,500 amps). It is suitable for LV and MV applications and is available in a wide range of frame sizes. It can be used for both single and three-phase applications.The 1G3.5UM circuit breaker is typically used for industrial applications such as electric motor control, starter motors, and pumps. It can also be used in commercial applications such as lighting, air conditioning, and heating systems.

Working Principle of 1G3.5UM Circuit Breakers

The 1G3.5UM circuit breaker utilizes a thermal magnetic protection system. This system uses a thermal element to detect when the current is too high and then a magnetic element that trips the circuit breaker and interrupts the current.When the current increases beyond a certain level, the thermal element of the circuit breaker detects the rise in current and begins to heat up. This heating allows a bimetallic strip, which is located inside the breaker, to bend. The bimetallic strip is connected to a mechanical linkage, which in turn activates the magnetic element.The magnetic element operates by using an electromagnet which is activated when the current reaches a level where there is a risk of an overload. The electromagnet then trips the circuit breaker, cutting off the electricity supply to the circuit.

Conclusion

The 1G3.5UM circuit breaker is an important device in electrical engineering. It is a medium voltage circuit breaker that is used in a wide variety of applications and provides important safety features to ensure protection against electrical overloads. It utilizes both a thermal element and a magnetic element to detect and interrupt current when necessary, keeping both people and equipment safe.
