Circuit Breakers are used to protect both electrical circuits and the people and equipment that use them from damage caused by overloads, short circuits, and current surges. The SU3D20UC is an advanced circuit breaker designed to provide protection against those conditions. This article will discuss the application fields of the SU3D20UC and its working principle.

The SU3D20UC is designed to provide protection for electrical circuits in residential and commercial environments. This circuit breaker is designed to provide protection against overcurrents and short circuits, as well as surges. This advanced circuit breaker is designed to protect low-voltage installations, as well as motors, transformers, and other electrical appliances. It is also designed to offer additional protection against power supply interruptions, allowing the circuit to be reset without waiting for the power to be restored.

The SU3D20UC is a compact and lightweight circuit breaker that is easy to install and maintain. It is equipped with a trip release mechanism that is sensitive enough to be triggered even at low fault current levels. This ensures that the circuit breaker will trip quickly to prevent damage to the connected equipment. The unit is also designed to provide protection against voltage transients, which can be caused by switching operations, line disturbances, and voltage sags. This helps to prevent damage to the control circuitry of connected equipment.

The working principle of the SU3D20UC is based on Magnetic Energy Release (MER). When the breaker is closed, a magnetic flux is created that increases with the current flowing through the breaker. When the current exceeds the pre-set value, the internal trip coil is released, producing a rapid release of magnetic energy. This energy is used to actuate the trip mechanism and open the circuit breaker, stopping the flow of current and protecting the equipment from damage.

The SU3D20UC is an advanced circuit breaker that offers a range of features for protection against damage caused by overloads, short circuits, and surges. It is designed to provide protection in residential and commercial environments, and can be used to protect low-voltage installations, as well as motors, transformers, and other equipment. Its functioning is based on Magnetic Energy Release (MER), which enables it to trip quickly to protect connected equipment in case of overcurrent or short circuit.
