Circuit breakers are an important part of electricity and electrical systems. They are used to protect electrical equipment from overcurrents, short circuits, and other risks. 3D10UM is a circuit breaker designed to protect medium to heavy equipment and systems from electrical faults and overcurrents. It also provides protection against earth fault and overvoltages.

3D10UM uses an electro-mechanical design. It has two to three sets of contacts. One of which is an operating contact that is used to open or close the circuit when the breaker is tripped. The other contacts are used to sense and sense earth and overvoltage. When an overload or fault occurs, the breaker will trip, disconnecting the protected equipment from the power supply.

The 3D10UM is primarily used to protect medium to heavy equipment from overcurrents and short circuits. It is also suitable for use in hazardous areas as it can be configured for use with a variety of different protective devices. It is also certified for use in applications where ground and neutral are connected, such as AC electrical systems.

The working principle of the 3D10UM is based on the principle of thermodynamics. It uses an electro-thermal relay which is connected to the operating contact. When the overload or short circuit occurs, the electro-thermal relay will expand and trip the breaker. The electro-thermal relay ensures that the breaker will trip even if there is a low-level current so it can protect medium to heavy equipment.

The 3D10UM also has overvoltage protection. It is designed to disconnect the protected equipment from the power supply when there is an overvoltage. This ensures that the equipment is not damaged by high voltage surges. The circuit breaker is also designed to react within 10 milliseconds, meaning that it can effectively protect against lightning strikes.

The 3D10UM is used in a variety of different applications. It is suitable for industrial, commercial, and domestic use. It is often used in manufacturing plants, airports, and power plants. It is also used in medical facilities, churches, and schools.

Overall, the 3D10UM is an important piece of safety equipment used to protect medium to heavy electrical equipment and systems from overcurrents and faults. It is designed to provide efficient, reliable protection against dangerous overcurrents, short circuits, and overvoltages. It is suitable for a variety of applications and is certified for use in hazardous areas. It has a fast response time, making it an ideal choice for any kind of electrical installation.
